Resistivity Analyzer and Control System

The RealTech Controls Model ETX Resistivity Analyzer utilizes an ECD S80 Resistivity sensor that converts the analog signals from the electrode cartridge into a digital protocol that allows two-way communications with the transmitter. The identity of the sensor, measurement type, and serial number, are stored in the sensor’s memory along with three calibration registers. The large, back-lit display shows the measurement (or both measurements if dual channel), temperature, relay statuses, and mA % output. When connected to the ETX digital analyzer, the sensor’s information is uploaded to the analyzer configuring the display and outputs of the transmitter to the values appropriate to the sensor’s measured parameter.
