Gems Sensors Introduces New Ultrasonic Level Switches for Challenging Fluid Monitoring



Plainville, CT, October 2001. Gems Sensors introduces at Chem Show 2001 two new series of liquid level switches that feature solid-state, ultrasonic technology. The single point ULS-50 Series incorporate submersible IP68 housings of either polypropylene or PFA Teflon®. The multi-point ULS-60 units are general-purpose non- contact level controllers; two versions are available to measure from 3.6 inches to 12 feet. Gems ultrasonic liquid level switches are designed for acids, ultrapure and wastewater, inks and paints, slurries, food and beverage, semiconductor process chemicals, oils, petroleum distillates and other coating or aggressive liquids.

Gems Non-contact ULS-60 Series mount in the top of a tank and provide two integral relays for user specified level switching setpoints. Relays are latching SPDT types for N.O. or N.C. operation and are rated to 250 VAC, 1 OA, 0.5 hp. Users use a potentiometer for field calibration of high and low liquid level points; the latching relays control pumps, valves and alarms. Resolution for this series is 0.125" with accuracy of ±0.25 of span. ULS-60 switches incorporate automatic temperature compensation over entire range. Power requirement is 120 VAC. Operating Temperature ranges from -40°F to +140°F; pressure is rated at 30 psi, max.

ULS-50 Series switches feature wetted materials of either all-polypropylene or all-PFA Teflon' for excellent compatibility with a broad range of liquids, including those with light coating or scaling characteristics. FET or relay output provides a reliable switch interface with remote devices such as a PLC, SCADA or alarm. This series mounts via 3/4" NPT boss in tank top. side or bottom, and also provide a 3/4" NPT conduit connection. Sensors are available in two lengths: 0.7 inch or 2.1 inch, each providing accuracy to ±1 mm. Power requirement is 12 to 36 VDC. Operating Temperature ranges from -40°F to +194°F; pressure is rated at 150 psi, max. N.O. or N.C. switch operation is selectable. ULS-50 Series switches carries CSA approval and CE compliance.

Smarter Products, Better Solutions is how Gems Sensors is shaping the future of fluid sensing. Gems offers engineers the industry's largest selection of liquid level, flow and pressure sensors and controls.
