Nt-93420 temperature transmitter is an instrument that converts temperature variables into transmittable standardized output signals. It is mainly used for the measurement and control of industrial process temperature parameters.

The transmitter with sensor usually consists of two parts: sensor and signal converter. Sensors are mainly thermocouples or thermal resistors; The signal converter is mainly composed of measurement unit, signal processing unit and conversion unit (since the industrial thermal resistance and thermocouple graduation table are standardized, the signal converter is also called transmitter as an independent product). Some transmitters have added display unit, and some have field bus function.
