SENSORS: The U003 from Innovative Solutions is a compact and low-cost liquid level switch that uses ultrasonic technology to detect the presence of fluid between two piezoelectric crystals sealed within the sensor gap.
The all 316 stainless steel, all solid-state U003 has no moving parts, may be mounted vertically or horizontally, and provides a simple and reliable alternative to float type level controls. It mounts with a standard ¾-inch NPT fitting (optional threaded connections or flanges also available) never needs calibration, can be provided with actuation lengths up to 100 inches from the mount and is available with an NPT male conduit connection, NEMA enclosure or other connector options.
The U003 is offered with a standard current shift output, (8mA “dry”, 16mA “wet”) or a SPDT relay, 0.5A output. The 1-inch diameter stainless probe is easy to clean, fits easily into confined spaces in any orientation and can operate in system pressures up to 800psig.
