CDTX-300 Series is a pH and Conductivity Transmitter Designed to Accept Signals Directly from a pH Electrode and a Conductivity Probe at the Same Time
Direct Connection of the Probes to the Transmitter Assures a Positive Electrical Connection with No Signal Loss. This Transmitter is Most Useful in Remote Process Control Applications.

The CDTX-300 two-wire transmitter is widely used for process control
in industry today. This instrument is particularly useful in industrial
conditions where electrical interference is an important factor. By
galvanically isolating the signals, any interference created is
prevented from reaching the transmitter. A loop powered isolator may be required when
connecting to data acquisition equipment. The CDTX-300 uses
two wires which reduces costs and eliminates the need for
expensive coaxial cable. Two-wire transmitters are ideal when
used in remote applications that do not have AC power available.
The CDTX-300 series conductivity transmitter uses top of-the-line,
4-Ring Potentiometric probes. As opposed to the more widely used
2-Ring Amperometric method, the 4-Ring Potentiometric method
provides the highest accuracy and repeatability attainable.
When measuring liquids that have a high conductivity, the 2-Ring
system is susceptible to polarization. 4-Ring electrodes 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.
