Application of LABOM temperature transmission module

Application of LABOM temperature transmission module

After zeroing, the signal is input for signal amplification during operation. The amplified signal is then processed by a converter and output as a 4-20mA DC current; The other path is processed by an A/D converter and displayed in the header. There are two types of linearization circuits for transmitters, both of which use feedback methods. The LABOM temperature transmission module is calibrated using positive feedback method, and the thermocouple sensor is calibrated using multi segment line approximation method. There are two display modes for integrated digital temperature display.
