Thermal resistance module suitable for oil-way temperature acquisition of hydraulic station

The utility model discloses a thermal resistance module suitable for oil-way temperature acquisition of a hydraulic station. The module comprises a microprocessor with an analog front end conditioning circuit. The signal input end of the microprocessor is electrically connected with a plurality of thermal resistors. The RS485 bus communication interface of the microprocessor is connected with a PLC control cabinet on a far-end in a communication manner. The module is advantaged in that through connecting the RS485 bus communication interface of the microprocessor with the PLC control cabinet on the far-end, and installing the thermal resistance module close to a sampling point position, routing distance of a thermal resistance sampling signal line is greatly shortened, anti-interference capability is improved, and a matched transmitter is not needed. Since the temperature acquisition points of a hydraulic station system is in large quantity, the thermal resistance module has effect of gathering sampling signals. Only one shielding cable is needed from the hydraulic station to the PLC control cabinet.
