Conductance probe

SENSW-LWF

Characteristic features

•  Gold plated interdigital structure as sensor surface
•  AC voltage signal evaluation
•  Low AC test current

Areas of application

•  Fill condition monitor
•  Leakage probe
•  Foam monitor
•  Analysis of rain water
•  Industrial applications
•  Laboratory systems

Application areas

The probe senses ion flow in conducting liquids. Electrolysis effects 
are prevented by gold plated surface and AC voltage evaluation, and 
hence, a reliable switching behaviour is also guaranteed in contamina-
ted media. Typical application areas come up as a fill condition monitor 
in rainwater tanks, limit sensor for pumping plants or for monitoring of 
cooling water level in plants.

The conductance probe is suitable for connection to Universal sensor 
switching module SENSW-MOD12V, SENSW-MOD24V and SENSW-
GEH230V, which performs the evaluation and provides a switching 
output through a potential free relay.
