2.Product overview
CWDZ15 series temperature transmitter products use PT100 as signal
measuring element, and through computer automatic testing, the temperature
compensation of zero point and sensitivity in wide temperature range is
carried out by laser resistance adjustment technology. The amplification
circuit is located in the stainless steel case, which converts the sensor
signal into standard output signal, giving full play to the technical
advantages of the sensor, so that the CWDZ15 series temperature transmitter
has excellent performance. It has anti-interference, overload, small
temperature drift, high stability, high measurement accuracy, and is an
ideal temperature measurement instrument in the field of industrial
automation.
3.Working principle
Temperature transmitter is the resistance effect produced by PT100
sensor under the influence of temperature. It generates a differential
voltage signal by special processing unit conversion. This signal is
transformed into standard analog or digital signal by special amplifier.
