Level-Trac LT-120/LT-140 Electronic Control Unit

Level-Trac LT-120 and LT-140 Control units are designed to be used with any conductivity probes used for the discrimination of water and vapor (steam).

The Control Unit delivers a low voltage common signal to a water column, which completes a circuit when a probe installed on the water column makes contact with water. 

The Control Unit provides the user with a set of contacts for each probe, and the facility for an optional indicator.
