When you are responsible for keeping tanks safe, pumps protected, and production flowing, you need a level switch you can trust. The VEGASWING 63 vibrating level switch is designed exactly for that role: a robust, universal point-level switch for liquids that delivers reliable switching even in harsh, high-pressure, and high-temperature environments. In this blog, we will explore how the VEGASWING 63 vibrating level switch works, what makes it different, and how you can apply it confidently in real-world systems.
From chemical tanks to food and beverage vessels, the VEGASWING 63 vibrating level switch gives engineers a simple, precise way to detect high and low levels without relying on conductivity, capacitance, or moving parts. Its tuning-fork principle means that as long as the fork is in contact with liquid, it will switch accurately—regardless of mounting position or liquid conductivity—making the VEGASWING 63 vibrating level switch a smart choice for many industries.
What Is the VEGASWING 63 Vibrating Level Switch?
The VEGASWING 63 vibrating level switch is a point-level sensor for liquids that uses a piezo-driven tuning fork to detect when a liquid reaches a specific level. Instead of measuring a continuous level like a radar transmitter or differential pressure device, the VEGASWING 63 vibrating level switch provides a clean on/off signal at a defined point—ideal for high-level alarms, low-level cut-out, and pump dry-run protection.
At its core, the VEGASWING 63 vibrating level switch consists of a short, robust fork that vibrates at around 1200 Hz. In air, the fork oscillates at its natural frequency. When the fork is covered by liquid, that frequency changes, and the electronics recognize this shift and change the output state. This simple, direct principle is what makes the VEGASWING 63 vibrating level switch so universal: it does not care whether the liquid is conductive or non-conductive, clear or colored, or has changing dielectric properties.
The VEGASWING 63 vibrating level switch is designed for liquids with densities from approximately 0.5 to 2.5 g/cm³. By default, the sensor is calibrated to water (1.0 g/cm³), but the internal density adjustment makes it easy to adapt the VEGASWING 63 vibrating level switch to lighter liquids such as solvents or hydrocarbons. As long as the density is within range, the fork will detect the interface reliably.
Another important characteristic of the VEGASWING 63 vibrating level switch is that it is independent of mounting orientation. You can mount it vertically from the top, horizontally through the side, or even at an angle, and the switching still occurs with millimetre accuracy at the tuned fork level. This mounting flexibility means a single VEGASWING 63 vibrating level switch can solve multiple application types across a plant.
How the VEGASWING 63 Vibrating Level Switch Works
To understand why the VEGASWING 63 vibrating level switch is so reliable, it helps to look at how the tuning-fork technology operates. The fork in the VEGASWING 63 vibrating level switch is excited by a piezoelectric drive, which causes it to vibrate at a defined resonance frequency. The electronics constantly monitor this frequency and detect when the fork is damped by contact with a liquid.
In air or gas, the tuning fork of the VEGASWING 63 vibrating level switch vibrates freely. When the process liquid covers the fork, the added mass and damping change the oscillation frequency. The electronics detect this frequency shift within a fraction of a second and convert it into a switching signal on the relay or transistor output. This quick reaction makes the VEGASWING 63 vibrating level switch very effective for critical alarms, like overfill prevention or pump protection.
The VEGASWING 63 vibrating level switch has a fork length of around 38 mm and a hysteresis of roughly 2 mm when mounted vertically. That means the difference between switch-on and switch-off levels is very small, giving you a sharp, repeatable switching point. For many engineers, this is one of the main advantages of using a VEGASWING 63 vibrating level switch rather than a float switch or other mechanical device.
Another reason the VEGASWING 63 vibrating level switch is trusted is its insensitivity to buildup and coating. Because the fork vibrates at a high frequency (~1200 Hz), light deposits are often shaken off. The sensor does not rely on a clean electrode surface like some capacitive or conductive probes. This makes the VEGASWING 63 vibrating level switch a good option in applications with some fouling or crystallization, as long as coating does not completely immobilize the fork.
Response time is also critical in safety systems. The electronics of the VEGASWING 63 vibrating level switch provide a switching delay of roughly 500 ms, fast enough for most tank applications. Combined with its mechanical robustness and approvals, this makes the VEGASWING 63 vibrating level switch a solid choice for demanding industrial environments.
Key Technical Specifications of the VEGASWING 63 Vibrating Level Switch
When selecting the VEGASWING 63 vibrating level switch for your plant, it helps to understand its technical envelope. These specifications ensure that the VEGASWING 63 vibrating level switch can handle tough operating conditions while still providing accurate level detection.
The process pressure range for the VEGASWING 63 vibrating level switch is typically from -1 to +64 bar. Threaded process connections can even be rated up to 100 bar at lower process temperatures (up to about 50 °C), which makes the VEGASWING 63 vibrating level switch suitable for pressurized tanks and pipelines in chemical, petrochemical, or energy applications. This high-pressure tolerance is one of the reasons operators choose the VEGASWING 63 vibrating level switch over lighter-duty switches.
In terms of process temperature, the VEGASWING 63 vibrating level switch can handle media from around -50 °C up to +250 °C. This wide temperature range opens up applications in hot oil, steam-related circuits, or high-temperature chemical processes.

The minimum switching power of the VEGASWING 63 vibrating level switch is around 50 mW, with maximum ratings up to 750 VA for AC loads and 40 W for DC loads. For applications that require different signaling methods, the same mechanical platform of the VEGASWING 63 vibrating level switch is available with contactless solid-state outputs, NPN/PNP transistor outputs, two-wire current signals (like 8/16 mA), or NAMUR versions for intrinsically safe circuits.
Wetted materials are another key part of the specification. The standard VEGASWING 63 vibrating level switch uses 316L stainless steel for all parts in contact with the process, which gives good corrosion resistance for many water-based and mild chemical applications. For more aggressive media, the VEGASWING 63 vibrating level switch can be specified with alternative materials such as Hastelloy C, Alloy 400, or protective coatings like PFA or ECTFE. This flexibility allows the VEGASWING 63 vibrating level switch to be tailored to specific chemical resistance needs.
Approvals and Hygienic Design of the VEGASWING 63 Vibrating Level Switch
One of the strongest reasons to choose the VEGASWING 63 vibrating level switch is its wide set of safety, explosion-protection, and hygienic approvals. These certifications demonstrate that the VEGASWING 63 vibrating level switch has been independently assessed for use in hazardous and sanitary applications across the globe.
For hazardous areas, the VEGASWING 63 vibrating level switch offers approvals such as ATEX, IECEx, FM/UL, and CSA, covering intrinsic safety (Ex i), flameproof (Ex d), and dust ignition protection (Ex t) depending on the configuration.

This means the VEGASWING 63 vibrating level switch can be cleaned in place (CIP) and sterilized in place (SIP) when installed with suitable fittings, helping to maintain product purity and safety.
The VEGASWING 63 vibrating level switch is also available in SIL2-qualified versions for functional safety applications. When integrated correctly, the VEGASWING 63 vibrating level switch can form part of a safety instrumented function (SIF) as a high-level alarm or shutdown in critical vessels. This level of certification is a strong indicator that the VEGASWING 63 vibrating level switch is designed for serious industrial safety duties.
Because the same basic platform of the VEGASWING 63 vibrating level switch can satisfy both hazardous-area and hygienic requirements, it is a powerful choice for global companies that want a single, standardized level-switching technology across multiple plants.
Installation Tips for the VEGASWING 63 Vibrating Level Switch with Tube Extension
The VEGASWING 63 vibrating level switch with tube extension is especially useful when the switching point needs to be located deep inside a tank or vessel. With the right installation practices, you can get the best performance and longest life from your VEGASWING 63 vibrating level switch in these applications.
First, remember that the tuning fork of the VEGASWING 63 vibrating level switch must be placed at the exact height where you want the switch to change state. The fork has notches on it that indicate the switching point, typically around 13 mm above the fork tip for water when the VEGASWING 63 vibrating level switch is mounted vertically. When you position the fork, align these notches with the desired level and account for any process conditions like turbulence or agitation.
The tube extension of the VEGASWING 63 vibrating level switch allows the switching point to be located up to several meters away from the process connection. In tall tanks, you may need a support for the tube to avoid mechanical stress or vibration. Vega offers lock fittings and welded sockets that make it easier to fix the VEGASWING 63 vibrating level switch at the correct depth and maintain sealing integrity.
Orientation also matters for long-term performance. In side-mounted applications, it is generally recommended to orient the fork tines of the VEGASWING 63 vibrating level switch vertically, so that buildup and sediment fall away more easily. This orientation reduces the risk of false switching caused by heavy deposits. For viscous or sticky liquids, correct positioning of the VEGASWING 63 vibrating level switch fork is especially important.
Sealing is another key installation aspect. The process connection of the VEGASWING 63 vibrating level switch often uses gaskets such as Klingersil C-4400 or compatible materials. Proper torque on threaded or flanged connections helps maintain a leak-tight joint. For hygienic applications, ensure the VEGASWING 63 vibrating level switch is installed with the correct hygienic adapter (Tri-Clamp, DIN, Varivent, etc.) and that all surfaces are clean and compatible with CIP/SIP procedures.
Wiring the VEGASWING 63 vibrating level switch is straightforward, but it should follow the specific wiring diagram for the chosen output. The DPDT relay version has two changeover contacts, providing redundant or independent alarming possibilities. A separate grounding terminal on the housing of the VEGASWING 63 vibrating level switch ensures proper earthing in line with electrical codes.
For commissioning and diagnostics, an optional PLICSLED display and adjustment module can be plugged into the housing. This module lets you see the status of the VEGASWING 63 vibrating level switch and fine-tune parameters on site, which simplifies start-up and troubleshooting.

Because of its robust design and broad approvals, the VEGASWING 63 vibrating level switch appears in a wide variety of industries. Any process that needs reliable high or low point detection in a liquid can benefit from the VEGASWING 63 vibrating level switch.
In storage tanks, the VEGASWING 63 vibrating level switch is commonly used as a high-level cutoff to prevent overfilling. It can be mounted at the maximum allowable tank level so that when the liquid reaches the fork, the VEGASWING 63 vibrating level switch closes or opens a circuit to stop filling or trigger an alarm. For low-level protection, another VEGASWING 63 vibrating level switch can be placed near the tank bottom to detect when the liquid falls to a minimum operating level.
In pump systems, the VEGASWING 63 vibrating level switch is often used as dry-run protection. Installed in a suction line, sump, or wet well, the VEGASWING 63 vibrating level switch detects when the liquid level drops below a safe limit. The pump can then be stopped before it runs dry, which protects mechanical seals, bearings, and impellers from damage.
The chemical and petrochemical industries use the VEGASWING 63 vibrating level switch to protect reactors, day tanks, and buffer vessels. Because the VEGASWING 63 vibrating level switch works independently of conductivity or dielectric constant, it can handle many different liquids, from caustics and acids to solvents and fuels, as long as they fall within the density and temperature range.
In water and wastewater treatment plants, the VEGASWING 63 vibrating level switch is suitable for clean water, process water, and certain waste streams. It can monitor boiler feed tanks, condensate receivers, clarifiers, and chemical dosing tanks. The VEGASWING 63 vibrating level switch provides a simple on/off signal that PLCs and control systems can use to start and stop pumps or open and close valves.
Food and beverage plants use the VEGASWING 63 vibrating level switch in mixing vessels, storage tanks, and CIP return lines. With hygienic connections and EHEDG/3-A approvals, the VEGASWING 63 vibrating level switch can be cleaned and sterilized without needing to be removed from the line. This saves time and reduces the risk of contamination.

Choosing Between VEGASWING 63 and Other Vibrating Level Switch Options
Within Vega’s portfolio, the VEGASWING 63 vibrating level switch sits alongside several related tuning-fork models. Understanding where the VEGASWING 63 vibrating level switch fits in the range helps you choose the right sensor for your application.
For compact applications, there are smaller forks designed for space-saving installations. Some of these, such as other VEGASWING family members, are intended for shorter insertion lengths or lower pressures. The VEGASWING 63 vibrating level switch, however, is designed as a robust, all-round solution that supports tube extensions up to several meters and handles high pressures and temperatures.
When you are dealing with bulk solids rather than liquids, the VEGASWING 63 vibrating level switch is not the right choice. Instead, Vega offers alternatives like VEGAVIB or VEGAWAVE for powders and granular materials. These still use the vibrating principle but are optimized for solids. For liquids, though, the VEGASWING 63 vibrating level switch remains a flexible, universal option.
There are also alternative technologies to consider, such as capacitive, conductive, or ultrasonic level switches. These can be useful in specific niches, but each has limitations that the VEGASWING 63 vibrating level switch can overcome. Capacitive switches may be sensitive to coating and changes in dielectric constant. Conductive probes require conductivity and may be affected by scaling. Ultrasonic gap switches may be influenced by gas bubbles. In contrast, the VEGASWING 63 vibrating level switch responds mainly to density at the fork and remains stable in many different conditions.
Continuous level measurement technologies such as radar, guided wave radar, or differential pressure transmitters are the right choice when you need a full analog level signal. However, they are often more complex and costly when you only need a point-level alarm. In such cases, the VEGASWING 63 vibrating level switch offers a simpler and more economical solution.
Ultimately, the decision often comes down to reliability, approvals, and flexibility. If you need one technology that can be used across many vessels, pressure ranges, and industry approvals, the VEGASWING 63 vibrating level switch is a strong candidate. It keeps the principle simple but delivers the robustness and documentation needed for modern plants.
