Compact Vibrating Fork Level Switch

The system is available in two versions - Integral (Standalone) &Two Part

.

In the integral system, the controller is integral with the sensing probe.

In two part system, the controller is separate from the probe and can be mounted remotely

.

The sensing probe is of rugged construction & available in two designs-standard & high temperature

The sensing probe is fitted with an enclosure at its top end, which holds the control electronics and its lower end holds a SS tuning fork, which vibrates at its mechanical resonance frequency of 120 Hz, created through a piezo crystal when in air.

However, when the tuning fork is covered with liquid / slurry, its vibrations get damped.

This is sensed by the control electronics, which changes the status of output relay contacts.
