Product Line Overview
The One Series electronic pressure switches and electronic temperature switch set the standard for solid-state digital process monitoring. With a fully adjustable set point & deadband and 0.1% repeatability, the One Series is suitable for a wide variety of harsh and hazardous applications. Available in Type 4X enclosures for explosion-proof and non-incendive area classifications, these electronic switches are designed to provide protection for plants, capital equipment and people.
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.
Consider a highly repeatable and fully adjustable deadband switch for applications where high cycle rate is present. With no moving parts, the One Series digital solid-sate design is uniquely suited for controlling pump and compressor stop/start cycles. And 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 only one connection to the process
For plant upgrades, the One Series is the most cost-effective choice. 2-Wire models utilize 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 amperes or 2 fully-independent set points and deadbands and the 4-20 mA output.
Adjustability, accuracy, versatility, intelligence – see what the One Series can do in your critical application.
