One Series Hybrid Transmitter-Switches
The One Series electronic pressure and temperature transmitter-switches set the standard for smart digital process monitoring. With a fully adjustable set point and deadband and 0.1% repeatability, the One Series performs in a wide variety of applications. Available in Type 4X enclosures approved for intrinsic safety, flameproof and non-incendive area classifications, these hybrid transmitter-switches are designed to provide transmitter, switch and gauge functions all-in-one rugged enclosure that can withstand the rigors of harsh and hazardous environments.
Overview
NEW! One Series Pressure and Temperature Transmitter-Switches Include HART® 7 Communication
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.

Benefits
- Liquid crystal display provides the process variable, self diagnostics information and alarm status
- IAW® (I Am Working) self-diagnostics constantly monitor the health status of the control to eliminate the “blind switch” issue
- 2-Wire models drop in place of existing mechanical switches and use the same wiring and control schemes providing a cost-effective upgrade path
- Loop-powered models provide a HART 4-20 mA transmitter output and include programmable solid-state relay (SSR) switches effectively replacing a transmitter, switch and a gauge
- All transmitter and switch functions are programmable using a HART communicator or the keypad on the display
- Two independent SSRs combine with a 4-20 mA output for stop/start, window mode and starting permissive applications
- Solid-state design allows for switching in high cycle rate applications without degredation
- Option M041 provides certified dual seal pressure sensor
