The LVU-230 and LVU-260 liquid level switches are the ideal solution to a host of liquid-level sensing and control applications. Their small size and standard ¾NPT fittings make them suitable for new or existing applications. The LVU-230 models have a relay output along with a 316 SS or PVDF® sensor and an integral miniaturized, encapsulated electronic control unit mounted in a cast aluminum, explosion-proof, watertight enclosure. The LVU-260 is a 2-wire, 4 or 20 mA output system.

Both use an ultrasonic wave propagation sensor mounted in the liquid medium. The electronics generates a continuous wave ultrasonic signal that completely illuminates the liquid-sensing area. The absence of liquid in the sensing area causes the ultrasonic signal to dissipate, which the electronics senses as a "dry" condition (and provides a 4 mA output signal in the LVU-260). When liquid is present, the amplitude of the ultrasonic signal increases, indicating a "wet" condition. This signal is converted by the electronics and energizes the 10 A relay (LVU-230) or a 20 mA output signal (LVU-260). The LVU-230 electronics may be set to provide the control output to an alarm, pump, or other device on either a dry or wet condition.
