A pH loop comprises a pH electrode selectable from a variety of configurations, a cable, and a TruTrans™ transmitter.
The pH electrode includes the reference and sensing electrodes, an optional temperature sensor, and the electrical connector that is connected to the transmitter using a cable (6 ft [1.83 m] or 10 ft long [3.05 m]). For a given transmitter, the pH electrode can be replaced. The pH electrode can be separated from the cable and transmitter for sterilization. The transmitter integrates the signal processing, power conversion, 4-20 mA output signal generation, and user interface functions in one package.
