Description
The embedded temperature sensor is installed in the stator core winding of large and medium-sized motors and wind turbines. As it is installed in the stator core slot, it can directly measure the operating temperature of the core winding. The product uses high-strength glass fiber resin material with high insulation strength, and is used for temperature measurement of high-voltage motors and generator windings. The product has F-class/H-class temperature resistance and insulation performance, which can timely reflect the operating load status of the motor and ensure the safe operation of the motor. This sensor has the characteristics of high accuracy, stable operation, and long operating life.
This sensor has two materials: insulation and metal temperature measuring end, and its performance meets the JB/T10500 embedded thermal resistance standard for motors. Customizable high-voltage and explosion-proof products.

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;
