What is the difference between embedded thermal resistors and armored thermal resistors for motors?

The embedded thermal resistor for motor (referred to as thermal resistor) is suitable for measuring the temperature of motor windings and motor cores. Platinum thermal resistors are used as temperature sensors and display instruments to measure the temperature of motor windings or stator cores. They are also suitable for other mechanical devices with similar temperature measurement requirements. The installation is particularly simple and directly displays the actual working temperature of the coil.

Embedded thermal resistor for motors implements standard JB/T10500.1-2005 Graduation number: Pt100
Although armored thermal resistors are widely used in industry, their application is limited by their temperature measurement range. The temperature measurement principle of thermal resistors is based on the characteristic that the resistance value of conductors or semiconductors changes with temperature. It has many advantages. It can also transmit electrical signals remotely, has high sensitivity, strong stability, good interchangeability and accuracy, but requires power excitation and cannot measure temperature changes instantaneously. Industrial thermal resistors generally use Pt100, Pt10, Cu50, Cu100. The temperature measurement range of platinum thermal resistors is generally minus 200-800℃, and that of copper thermal resistors is minus 40 to 140℃. Thermal resistors are classified into the same types as thermocouples, but they do not require compensation wires and are cheaper than thermocouples.
