Detailed introduction
Motor-specific thermal resistors are divided into three categories: motor embedded thermal resistors, bearing end face thermal resistors and armored thermal resistors. The temperature measuring element currently used in the world is Pt100. Motor embedded thermal resistors are temperature sensors specially used for measuring the temperature of motor (motor or generator) windings or stators. They are buried in the windings or stator cores. After connecting to secondary instruments, they can directly display the temperature of the windings or stator cores in operation, and can also be transmitted to the control room for alarm or control. Bearing end face thermal resistors are sensors specially used to measure the temperature of bearings or bushes at both ends of the motor. Armored thermal resistors are sensors used to measure the temperature of large motor bushes or coolant.
● Sensor structures are divided into winding structures and thin film structures.
● Winding structure thermal resistors are suitable for measuring the average temperature of objects (or media), and thin film structures are suitable for measuring single point temperature.
● The rated working current of the winding structure is ≤5mA, and the rated working current of the thin film structure is ≤3mA.
