    UE pressure switches, pressure transducers and pressure transmitters, and temperature switches and temperature sensors are designed for rugged, industrial environments. 

    Mechanical 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.

    Explosion-proof pressure transmitters provide continuous pressure monitoring in various hazardous area applications, specifically within the oil and gas industry. 

    Most products carry third party approvals such as UL, cUL, CSA, FM, and ATEX, and comply with CE. United Electric Products meet the "Produced in America" Requirements of the American Recovery and Reinvestment Act.

    Temperature sensors employ a variety of technologies including Thermocouple, RTD, Thermistor and Temperature Sensitive IC. A wide array of standard packages are available. Custom packages are routinely developed to suit specific applications.
