The Compact Vibrating Fork Level Switch is a versatile and reliable device designed for detecting both solid and liquid materials in industrial applications. Featuring a fork-shaped sensor that vibrates at a specific frequency, the switch detects changes in vibration when it comes into contact with materials, signaling the presence or absence of the substance.
This switch is constructed to endure harsh conditions, making it suitable for a wide range of industries, including food processing, pharmaceuticals, chemicals, and wastewater management. Its compact design allows for easy installation in tight spaces, while its robust construction ensures long-lasting performance. With minimal maintenance needs, it offers fail-safe operation to prevent overflow and enhance process safety, making it an essential tool for maintaining optimal levels in tanks, silos, and hoppers for both solids and liquids.
All liquids from free-flowing to viscosity up-to 10,000cP.
Suitable for side as well as top mounting.
Flow/No-Flow detection in pipe-lines.
Minimum and maximum fail safe field selectable.
Process temperature max 150 ºC.
Process pressure max. 15 bar.
Compact size.
Universal industrial power supply (15 to 80 VDC & 15 to 260 VAC).
Low power consumption.
No calibration required.
Various customized process connections like Threaded/Flanged/TC etc starting form 1/2″.
External test option using magnet test key.
Electronics of LFV11 excites the piezo-electric-crystals inside the tuning fork, which makes the fork tines vibrate at their natural resonance frequency in free air.
When the fork tines are immersed in liquid, the frequency of fork vibration falls due to the density of liquid.
This change in frequency is detected by the electronic circuit. Liquid presence is thus detected.
