Introduction to GWD60 Temperature Sensor
The GWD60 temperature sensor is suitable for places underground in coal mines with gas, coal dust, and explosive gases. According to different environments and locations in the coal mine, when the temperature around the sensor exceeds the set value, the sensor outputs an effective switch signal.
Characteristics of GWD60 temperature sensor
The GWD60 temperature sensor is a specialized temperature microcontroller probe 18B20. It is a high-precision, calibration free linear temperature/voltage converter and an intelligent microcontroller with V/A conversion. The temperature data output is sent to the main board of the sensor; The main board is processed by single chip microcomputer AT89C2051. It is equipped with upper and lower limit control. The Nixie tube on the sensor displays directly; It is adjusted by the microswitch, and the Nixie tube displays the ambient temperature at ordinary times. When the ambient temperature exceeds the set value, the sensor outputs a switch level signal. Has high sensitivity. High accuracy, calibration free, stable and reliable operation, etc.
