The ONE Series is a multifunctional smart transmitter and switch designed for pressure and temperature monitoring in hazardous environments, combining HART® communication, programmable switch outputs, and self-diagnostics in a single device. It features a 4X/IP66-rated epoxy-coated aluminum alloy enclosure with a tempered glass display window, two 3/4" NPT conduit entries, and wall or pipe mounting capability. The device supports loop-powered 4-20mA analog output with HART® version 7, and includes two independently programmable SPST solid-state switch outputs with MOSFET switching. Operating temperature ranges from -40 °F to 185 °F (-40 °C to 85 °C) for switch models and -40 °F to 176 °F (-40 °C to 80 °C) for transmitter models, with display visibility from 10 °F to 158 °F. Accuracy is 0.5% of full range span, and it is certified for cULus, IEC, and ATEX hazardous location use.
The ONE Series is a multifunctional device - switch, gage, and transmitter - that installs via a single process connection while utilizing existing wiring, reducing installation cost. Patented IAW® (I Am Working) self-diagnostics continuously communicate its health status, and increases operational and maintenance efficiency. Set point and deadband are fully adjustable and easily programmed through the display keypad or via HART connection. Certified for hazardous location, intrinsically safe and non-incentive area classifications. Typical applications that utilize the One Series include controlling rotating equipment - pumps, compressors, turbines, seal pot monitoring, filter monitoring, BOP and wellhead control, and cryogenic monitoring for LNG storage and transport.
