Solitune, Point Level Switches, Manufacturer, Supplier, Pune, India

We are Manufacturer, Supplier and Exporter of Solitune and our setup is situated in Pune, Maharshtra, India.

Compact Tuning Fork Point Level Switch For Solids

SOLITUNE is specially designed for detecting maximum and minimum level in vessels filled with free flowing fine-grained or powdery material. SOLITUNE 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
Universal Power supply for AC / DC operation
Relay or open collector PNP outputs available
Short fork design (100mm) for minimum insertion in small vessels
Available in 1 inch and above screwed mounting standards
IP 68 ingress protection
Selectable fail safe mode
LED indicators for status, alarm and normal operation
Density setting and switching delay selectable

Operating principle :

The Tuning Fork is kept vibrating at its mechanical resonant frequency by Piezo elements. When the service material covers the tines it resists its movement and so the vibrations are damped. The stoppage of vibrations is sensed electrically and the signal is 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.
