Introduction to GWD40 Temperature Sensor
The GWD40 temperature sensor is an instrument used to measure the environmental temperature underground in coal mines, in order to monitor the occurrence of fires, and can also be used for temperature measurement in other places. The measurement range of GWD40 temperature sensor is 0 ℃ -40 ℃, which is the conventional temperature range underground.
The output mode of GWD40 temperature sensor is 200-1000Hz, which is convenient for use with various coal mine environmental monitoring systems and monitoring substations.
The GWD40 temperature sensor has achieved a fully digital design. The temperature probe uses precision semiconductor temperature sensing components, and the output is a current type signal, without any adjustment of the entire circuit. The microcontroller integrates program memory, data memory, microprocessor, and input/output interface, with good performance and high reliability.
