LSA04 RF Capacitance Level Switch

Brand: Intempco Controls, Inc.

INTEMPCO LSA04 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, or a concentric probe needs to be installed.

The LSA04 includes a transmitter housed in a rugged enclosure, a mounting fitting and a rigid probe up to 20 feet (6.09 meters) long.

Probe material is SS316, supplied bare or Teflon jacketed. Additional standard features include and adjustable time delay, DPDT relay rated at 5 A, LED relay status indication, and a simple push button calibration.

Optional, DIN Rail Module is available, which can be installed up to 3,000 feet (914.4 meters) away from the process where calibration can be performed.
