pH and conductivity transmitter

The CDTX-300 two-wire transmitter from Omega is suitable for process control where electrical interference is an important factor. By galvanically isolating the signals, any interference created is prevented from reaching the transmitter.

The transmitter uses 4-Ring Potentiometric probes that eliminate the polarization effect by splitting the four rings into 2 current electrodes and 2 voltage electrodes. When placed in a conductive liquid, the 2 current electrodes take the alternating voltage and create a current. This alternating current produces a Buffer Field from which polarization is absent. The voltage is then measured in this field, assuring no altered readings.
