Temperature sensor of generator
Temperature measurement of stator winding

It is embedded in the part of winding that cannot be touched after the motor is made, and it cannot be replaced easily. Long term stability and longevity are particularly critical.
Element: Wire winding elements ensure a small rise of self-heating temperature. There are two types of single and double elements. The width and thickness of double-element platinum resistor are larger than that of single-element platinum resistor.
Insulation shell: Class F and Class H insulation materials can be provided.
Lead wire: Use high-temperature resistant and corrosion-resistant fluoroplastic insulated and sheathed control cables.
Customization features
The high-temperature heat-shrinking film package is placed outside the insulation shell of platinum resistor, which improves the insulation performance of the platinum resistor and protects the probe root to avoid wire breakage.
To facilitate installation, the outgoing direction of platinum resistor can be customized. It can be either the top outgoing line or the side outgoing line.
The lead wire of platinum resistor can be round wire, flat wire and loose wire.
The wire system is generally three-wire system, and it can be made into two-wire system and four-wire system according to the needs of users.
