Pressure Switches from United Electric Controls

Pressure Switches

United Electric Controls pressure switches are designed for rugged, industrial environments. Our mechanical pressure switch products utilize bellows, diaphragm or piston sensors to detect changes in process variables. These changes cause the sensor to deflect and operate a snap-action electrical switch. Enclosure designs range from cost-effective skeletons to cast aluminum or stainless steel. Our line of electronic pressure switches and electronic temperature switches combines self-diagnostics and digital electronics to provide 2-wire and loop powered instruments ideal for hazardous location plant upgrades. These solid-state switches provide 100% programmability for the set point and deadband while combining the gauge, switch and transmitter functions for extremely high reliability in safety instrumented systems (SIS) applications.

Our pressure switch bulletins are available in English and Spanish as indicated by the PDF icon below.

One Series Pressure Switch One Series
One Series Transmitter-Switch for Hazardous Locations
With an integral solid-state relay, the One Series can do much more than a typical process transmitter! In addition to monitoring the process, the application may call for providing an alarm or shutting down a pump or compressor, even actuating a valve. The One Series can provide the switch signal directly to these field devices, at the point of measure, without the precious time wasted by the control systemБ─≥s logic Б─⌠ in 60 milliseconds or less!
