LLS100 Miniature Conductivity Level Switch

Brand: Intempco Controls, Inc.

The LLS100 is truly a high quality level switch, which can be used in harsh environments, for liquid level limit detection in metallic and non-metallic tanks containing electrically conductive liquids.

The probe, fitting and housing are constructed of stainless steel 316; the isolator is Teflon.

The LLS100 sensor features built-in protection against reverse polarity, overvoltage and electrical shielding to deliver long-term reliability.

The output is relay SPDT which can be configured as either NO or NC (4-wire) or both NO and NC (5-wire).
