Level Sensor

Polygon offers Point Level Sensor which detects Liquid presence based on Conductivity Principle. The sensor can be placed at any desired height in a tank for descret level measurement.
 It comes with a DIN Rail mount evaluation unit & sensor probes. it provides a potential free digital output to a PLC, indicator or alarm device. You can have a number of such point level sensors in the tank at different levels to detect the Liquid Level in the Tank. It can be used as a static sensor to simply detect the presence or absence of the Liquid.
It works on extremely low current (a few micro-amperes) so can be used for liquids with extremely low conductivity. It cannot be used for non-conductive liquids, hydro-carbons & also inflammable liquids.
The sensor probe is made of SS304 material and is suitable for use with corrosive liquids compatible to SS304. 
SS316 & SS316L versions are also available for use in Pharma applications.
