The UE ONE Series Electronic Switch and Transmitter combines the functionality of a pressure or temperature switch, transmitter, and local display into a single compact device. Designed for industrial process applications requiring high reliability and operational flexibility, the ONE Series helps simplify installation, reduce leak paths, minimize maintenance requirements, and improve overall system performance.
Traditional installations often require separate switches, transmitters, gauges, and associated wiring. The ONE Series consolidates these functions into one intelligent instrument, helping reduce installation complexity, lower lifecycle costs, and improve process visibility.
Available in pressure, differential pressure, and temperature configurations, the ONE Series provides programmable switching, local indication, HART® communication capability, and advanced diagnostics in a rugged explosion-proof enclosure suitable for hazardous locations.
One of the key differentiators of the ONE Series is its patented IAW® (I Am Working) self-diagnostics technology, which continuously monitors device health and helps identify faults before they become process issues. The device can also detect plugged impulse lines and blocked pressure ports that could otherwise create inaccurate “live zero” readings during operation or maintenance.
The ONE Series is well-suited for facilities looking to modernize aging mechanical instrumentation while improving safety, reliability, and digital integration capabilities.
Westech Industrial provides product support, application guidance, commissioning assistance, and servicing for UE products across Canada. Our team can also assist with custom-fabricated instrumentation assemblies, control panels, and integrated process solutions where pressure and temperature monitoring devices are required.
