Level Switch - Conductivity Type

Conductivity type level switches are very commonly used for liquid level sensing and control applications. It is suitable only for conducting liquids.
Salient features:
• no moving part, free from maintenance.
• no special cable required for signal transmission, economical to install.
• long cable connection permissible between probe and evaluation unit.
• ac on probes for prevention of electrolytic deterioration of electrodes.
• low voltage on probe for operational safety.
• variety of control functions and installation system available, beside single point switching.
A] two point action for automatic pump control.
B] two point independent switching.
C] three point switching, two points with pump control logic and one independent point
d] four point switching having two-pump control logic.
° variety of probes available for various process conditions.
° multi channel -4 point independent switching available for various process conditions.
