pH and Conductivity Transmitter - Discontinued

CDTX-300

See All Models Below

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.

Description

The CDTX-300 model has been discontinued. Please see the CDTX-111/CDTX-112 as a possible alternative or contact our Flow Engineering Department.

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.
