WMT180A intelligent temperature transmitter module is a smart transmitter module with high precision and high stability. It can be installed in the case of a thermal resistor or thermocouple and functions as a converter to transmit the temperature signal to remote device. It inherits standard current or voltage output signal and can output HART protocol commands and some custom commands as well. It is compatible with more than ten types of thermocouple and thermal resistance signal transducers. This product USES 24 Σ - delta sampling chip, ensures high precision measurement. Anti-surge and anti-reverse connection design avoid mis-installation and mis-operation in engineering installation and enhanced software safety design is adopted to ensure long service life and stability.
