United Electric Controls One Series electronic pressure switches and electronic temperature switch

The United Electric Controls One Series electronic pressure switches and electronic temperature switch have a fully adjustable set point and deadband and 0.1% repeatability, and area available in Type 4X enclosures for explosion-proof and non-incendive area classifications.

Each One Series model incorporates intelligent self-diagnostics and can report detected faults before they become major safety issues. Plug port detection protects against sensor clogging. Nuisance trip filtering reduces false and spurious signals. The ability to capture pressure spikes and valleys provides process information to aid in the commissioning and debugging process.

These switches are designed to be highly repeatable and fully adjustable deadband switches for applications with a high cycle rate. With no moving parts, the One Series digital solid-state design is suitable for controlling pump and compressor stop/start cycles. With its digital process display and available 4-20 mA output, the One Series can provide the functions of a switch, gauge and a transmitter with one connection to the process.

For plant upgrades, 2-wire models use existing plant wiring. Loop-powered models provide high-capacity switching and a 4-20 mA output. External power supply models can handle currents up to 10 A or two fully independent set points and deadbands and the 4-20 mA output.

Multiple sensor types and ranges are available - gauge pressure up to 6000 psi, differential pressure up to 200 psid, and RTD temperature from -184 to 538°C.
