Level sensor control for conductive media

August 2007 Level Measurement & Control

Level control of extremely conductive media can be a problem as products that may appear to be non-adhesive can often leave an almost invisible but highly conductive film on the sensor body. The result can be a 'full' signal from the level transmitter, even when the container is empty. Rechner Sensors' Triple-G series capacitive sensors have been purpose designed for such applications. These sensors have PTFE bodies and are available in body sizes M32 x 1.5 and G1. Outputs are antivalent and there are both PNP and NPN versions.
