SBWR, SBWZ series temperature transmitter module is a 24V power supply, two-wire integrated transmitter. The product uses imported integrated circuits to amplify the signals of thermal resistors or thermocouples and convert them into 4-20 mA or 0-10 mA output current or 0-5 V output voltage. The armoured transmitter can directly measure the temperature of gas or liquid, especially in the low temperature range, which overcomes the influence of condensate on temperature measurement.


SBWR and SBWZ series temperature transmitter modules have the following characteristics: they can be directly installed in the sensor junction box, accurate signal, remote transmission (* 1000M), high accuracy, anti-interference, long-term stability, maintenance-free. This series of products have been widely used in various fields of industrial control.
