| Abstract: | Thermocouple is an important sensor of thermal measurement. Thermocouple temperature measurement modules are widely used in many control systems. In this paper, the theory of thermocouple temperature measurement is introduced. Combining the theory analysis and key points of EMC design, the Hite PLC thermocouple modules are designed with high precision, high anti-interference ability. And the performance specification of the module is listed. |
