LSA01 RF Capacitance Level Switch

Brand: Intempco Controls, Inc.

INTEMPCO LSA01 series RF level switches are highly reliable microprocessor based sensors designed to alarm on the high or low condition of liquids and certain dry bulk media in metal tanks.

In non-metallic tanks, a grounding rod needs to be installed. The LSA01 includes a transmitter housed in a rugged enclosure, a rigid probe up to 20 feet (6.09 meters) long and a fitting.

Probe material is SS316, supplied bare or PFA jacketed. Additional standard features include and adjustable time delay, SPDT relay, LED relay status indication, and a simple push button calibration.

Optional, DIN Rail Module is available, which can be installed up to 3000 feet away from the process where calibration can be performed.
Features
