Description
The winding platinum thermistor temperature sensor is used for temperature measurement of motor and transformer windings. It is installed in the end windings of the motor and transformer and can be installed separately according to the three-phase winding. This sensor has the characteristics of earthquake resistance, voltage resistance, high accuracy, good linearity, rapid thermal response, vacuum immersion resistance, small size, high sensitivity, and easy installation. The sensor probe shell can be customized to different materials such as metal, ceramic, PTFE, etc. according to the usage environment requirements

Note
1. During installation, protect the sensor lead out cable and strictly prohibit forceful pulling;
2. During the AC voltage withstand test of the motor, the sensor wire should be short circuited to ground, and the shielding wire should be grounded;
3.After the installation and connection of the sensor are completed, it is necessary to verify whether the wiring is correct and confirm before proceeding.It can avoid damage caused by strong electricity mistakenly connecting to sensors;
4. When the storage period of the sensor exceeds 1 year, the temperature resistance value and insulation resistance value of the sensor should be tested before installation to ensure good sensor performance;
