2-wire conductivity, pH/ORP pION transmitter

The intrinsically safe AWT210 two-wire universal transmitter is a single-channel device for the measurement and control of pH, ORP or conductivity in hazardous and non-hazardous area applications.

Operation simplicity is a key feature of the AWT210 with intuitive software, advanced self-diagnostics and its innovative plug-and-play modular design that enables users to achieve increased levels of efficiency through reduced process downtime.

Fieldbus & HART


The AWT210 offers the power of advanced digital communications in a simple, flexible design, enabling you to get up and running quickly.

  • 'Easy Setup' sensor configuration menus provide step-by-step guidance

  • Advanced self-diagnostics conforming to NAMUR NE 107 provide harmonized indication of device status

  • Multi-level security access prevents unauthorized modifications to transmitter configuration and calibration

  • One-Button sensor calibration saves time and money spent on routine maintenance

  • Common universal design for pH, ORP or conductivity measurement

  • Plug-and-play sensor and communication modules minimize stock holding and maximize operation uptime available with PROFIBUS™ PA, FOUNDATION™ Fieldbus™ or HART™ communications
