Vibrating Rod Point Level Switches, Vibrating Rod Level Sensors, India

We are Manufacturer, Supplier and Exporter of Vibrating Rod point Level Switches and our setup is situated in Pune, Maharshtra, India.

VIBROSENSE is a single element vibrating rod specially designed for detecting maximum and minimum level in vessels filled with free flowing fine-grained or powdery material. VIBROSENSE being a single element device, it overcomes the limitation of material getting stuck in-between the tines of a vibrating fork wherein both the tines are exposed to the service material. VIBROSENSE can be used for detecting the level of service material having grain size less than 10mm. Variation of electrical parameters of the service material such as conductivity and dielectric constant do not affect its operation. It can be used successfully for level detection of powders and granules of plastic, silica, sand, cement, chalk, pulverized coal, PET, Food grains, minerals, animal feed, Sugar & wood chips etc.

Salient Features :
Compact size with integral electronics
No calibration required so plug and play
No moving parts so no wear and tear
Single element exposed to media for reliable sensing
Open collector PNP output for external relay operation or for input to PLC
IP 68 ingress protection
Selectable fail safe mode
LED indicators for status, alarm and normal operation

Operating principle :

The sense rod is kept vibrating at its mechanical resonant frequency by Piezo electric elements. When the service material covers the rod it resists its movement and so the vibrations are damped. The stoppage of vibrations is sensed electrically and processed to signal an alarm and or control a relay. The relay contacts in turn can be used to control the feed motor or evacuation valve of the vessel.
