For electrodeless conductivity applications requiring a two-wire, loop powered transmitter, the Invensys Foxboro brand Model 876EC with Foxboro sensors provides the most flexible solution for wide ranging application conditions. Unlike other electrodeless conductivity measurement solutions, the Foxboro offering provides the widest choice of sensing and configuration selections, resulting in the best possible match for your application. The result is long service life, quick and easy application set changes, and savings in both material and labor costs.

The Foxboro 876EC is a 2-wire loop powered intelligent transmitter that, when used with appropriate electrochemical sensors, provides measurement, local display and transmission of electrodeless conductivity or concentration. The transmitter outputs a HART digital signal and a 4 to 20 mA analog output.
