LLS12 Conductivity Level Switch

Brand: Intempco Controls, Inc

The LLS12 is a high quality conductance level switch which can be used for liquid level limit detection in metallic or non-metallic tanks containing electrically conductive liquids.

The probe is stainless 316, the insulator is Teflon. Standard fitting is 1/4" NPT offered in Stainless 316 or Brass.

The LLS12 features built-in protection against reverse polarity, LED indication of state, overvoltage and electrical shielding to deliver long-term reliability. The output is transistor NPN or PNP.
