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 HART®– Enabled 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 and control schemes. Loop-powered hybrid transmitter models provide high-capacity switching and a 4-20 mA output. 4-wire models can handle currents up to 10 amperes at 240 VAC.
Adjustability, accuracy, versatility, intelligence – see what the One Series can do in your critical application.
