STT850

The core principle of a temperature transmitter is to convert the non-electrical quantity sensed by the temperature sensor (Temperature ) converted to a standard electrical signal 。Connect thermocouple (TC) or RTD (RTD) and other sensors, For thermocouple signals: Performs cold junction compensation (Corrects the effect of cold junction temperature changes ), amplifies the weak thermoelectric voltage, and perform linearization (Because thermoelectric voltage and temperature are nonlinear ) 。For RTD signals: Usually powered by a constant current source, converting its resistance change into a voltage change, Also performs linearization (Because resistance - temperature relationship is nonlinear ) 。The circuit also filters the signal to suppress interference 。The conditioned voltage signal is fed into the voltage /Current conversion circuit (V/I Converter ), accurately converted to industrial standard 4-20mA DC current signal (or other standard signals ) 。The current signal is linearly proportional to the measured temperature range, Strong interference immunity, Suitable for long-distance transmission to the control system 。
