LTX22 Capacitance Level Transmitter

Brand: Intempco Controls, Inc

The Intempco LTX22 is a capacitance level sensor designed for modulating level control of liquids in metallic tanks. 

The probe is normally installed in a steam boiler, or metal tank, where it is grounded through the process fitting, the boiler tank forming the ground return path. 

It can be used in a non-conductive tank if an grounding reference rod is provided. The probe measures level by measuring the change in capacitance as level changes in the tank. 

The micro-processor based electronics converts this capacitance change into a linear, highly accurate output signal. 

This signal may be used with one or more electronic modules to provide level control, level alarms, and/or outputs to a building management system. 

The LTX22 is available with an enclosure and installed electronics or an enclosure and remotely installed electronics in a NEMA 4 box. 

The connection is made via coax cable. Remote electronics are a preferred choice for higher ambient temperature applications.
