Kaidi KD-CWDZ15 High Precision Temperature Transmitter -50℃~300℃ For Liquid

CWDZ15 series temperature transmitter products use PT100 as the signal measuring element, and after automatic testing by computer, the zero point and sensitivity temperature compensation in a wide temperature range is carried out by the laser resistance trimming process. The amplifying circuit is located in the aluminum alloy shell, which converts the sensor signal into a standard output signal, which gives full play to the technical advantages of the sensor and makes the CWDZ15 series temperature transmitter have excellent performance. It is anti-interference, overload, small temperature drift, high stability, and has high measurement accuracy. It is an ideal temperature measurement instrument in the field of industrial automation.
