SWI U00X Series | Low-Cost Ultrasonic Gap Level Switch

Description

The U00X Solid-State Level Switch is a reliable, low-cost liquid level control for use in installations where mechanical float-type switches are impractical. The U00X is compatible with many liquids, regardless of the fluid's density or conductivity. The unit requires no calibration, withstands pressures up to 2,000 PSIG, and its compact, 7/8" diameter probe installs in any orientation. The U00X is constructed from durable and easy-to-clean 316 stainless steel with probe lengths available up to 100". Optional materials include CPVC, PVDF and Hastelloy C.

Principles of Operation

An ultrasonic transmitter and receiver detect the presence of fluid between two piezoelectric crystals sealed within the sensing gap. As the gap fills with liquid, an ultrasonic wave signal passes between the crystals and depending on the model, results in an output shift or activates a relay.
