LSA01-DT RF Capacitance Dual-Point Level Switch

Brand: Intempco Controls, Inc.

INTEMPCO LSA01-DT is a highly reliable microprocessor based ON/OFF RF Capacitance level switch with up to 2 independently adjustable non-interacting set points.

It may be used in liquids and dry bulk solids in metal tanks. In non-metallic tanks, a grounding rod needs to be installed.

The LSA01-DT system consists of signal transmitter mounted in an enclosure, a mounting fitting and a rigid probe of up to 20 feet (6,096 mm) long.

Probe material is SS316, supplied bare or PFA Teflon jacketed.

DIN Rail Remote Module features an adjustable time delay, field selectable Failsafe operation, 2 DPDT output relays, LED status indication, and a simple push button calibration.

It can be installed up to 300 meters (1,000 feet) away from the process where calibration is performed.
