453 Conductivity Transmitter

Two-Wire Conductivity Transmitter

IC CONTROLS has incorporated microprocessor technology into the two-wire transmitters. Conductivity measurement can be critical to your process and must be strictly monitored and maintained. Analyzer intelligence goes beyond measurement and control, providing the user with calibration data including sensor cell constant, range and diagnostics. Information can be communicated for trending or advanced control, even to remote locations. Ultimately, the user has superior control with a competitive advantage.


The analyzer stores the last calibration record Settings can be viewed, functions tested, and calibration updated using the front panel keypad without opening the enclosure.

These analyzers / transmitters are 2-wire 24 VDC operated. Installation costs are less because no 115/240 VAC is needed at the transmitter field location. They require a separate 24 VDC supply and typically a 4-20 mA receiver.

The industrial two-wire conductivity transmitter from IC CONTROLS, the Model 453, gives you maximum flexibility, reliability, and ease of use. The transmitter is easily applied and panel mounts in a standard ½ DIN size RFI/EMI-resistant case, with options available for pipe or wall mount. When needed, a very rugged explosion proof case, option -9, is also available.

The model 453 is not just a transmitter, it is a full conductivity analyzer! You get full sensor functions, standardize (cell constant calibration) and auto range adjustment, plus independent, program-adjustable 4-20 mA zero and span. Even with old deteriorated sensors, you enjoy higher accuracy over broad conductivity ranges. This analyzer corrects for sensor condition to give corrected precision readings.

Easy Program Does What You Expect
