ABB AWT420 Dual-channel Digital Transmitter
The AWT420 four-wire, dual channel transmitter offers true flexibility for measuring a wide variety of parameters in a single device.
Offering swappable communications and sensor modules, options for panel-, pipe- and wall-mountings and general purpose and safety enclosures, the AWT420 is the versatile single box solution for measuring a range of parameters including pH/ORP, conductivity and turbidity.
The AWT420 pH/ORP module is compatible with ABB’s full range of analog pH, redox (ORP) sensors in addition to most competitors’ sensors.
Factory calibrated sensor and communication modules minimize stock holding and maximize operation uptime.
Key features:
- Dual-channel measurement and control
- Mix-and-match analogue and EZLink digital sensors
- Integrated dual channel PID control for direct and reverse acting control or dual acid/base control (pH only)
- Flexible installation
- Full audit trail capability
- Easy and secure access to your data
With the AWT420, you get a single device that can be expanded readily to meet changing demands, both now and into the future.
Available in both corrosion resistant polycarbonate or a durable metal version with optional non-incendive approvals for hazardous area installation, it offers a versatile solution for use in utility- and industrial process-applications.
