CWB Series Temperature Transmitter
Inroduction
CWB series temperature transmitters use semiconductor temperature sensors, platinum resistances, etc. as temperature sensitive components, and output standard industrial signals after temperature compensation, digital circuit correction and signal conditioning.
Each type of product has undergone careful design, component screening, process verification and curing, cyclic loading and aging, environmental simulation testing and other processes to ensure that each product is stable and reliable.

Railway locomotives
Coal mines
Oil field
Chemical industry
Civil explosion
