Socket type thermal resistance, also called socket type platinum thermal resistance. Socket type thermal resistance temperature measurement is based on the resistance value of the metal conductor to increase with the increase of temperature and the temperature measurement. Most of the thermal resistance of pure metal material, is currently the most widely used platinum and copper connector with form, convenient installation. Socket type Pt thermal resistance element is used miniature ceramic tube and is arranged inside the holes around the platinum thermal resistance wire bodiless coil made sense of temperature sensor, temperature sensor made fairly small (minimum diameter can do with a diameter of 1.6 ~ diameter 1.2mm) it to make all kinds of micro temperature sensor probe. The connector form, convenient installation. Suitable for measuring temperature of liquid, gas and solid surface in the range of -200-+450.
Detail description of socket type thermal resistance
WZP-270 WZP-280 WZP-260 series socket type thermal resistance according to the new standard of our country JB/T8622-1997 for production. The working principle is that the resistance value of Pt resistance wire is changed with the change of temperature under the action of temperature. The relationship between temperature and resistance is close to the linear relationship, the deviation is very small, and the deviation is ignored with the increase of time, and the electrical performance is stable. The series of products has small structure, use a wide range, good reliability, thermal response time is short, and other advantages, formed many varieties, specifications of series of products for petroleum, chemical industry, power plant, metallurgy, light industry, food, textile, medical and health, scientific research, the agricultural and Mechanical industry to provide a new generation of high-quality products.

Outlet thermal resistance is sheathed thermal resistance, an extension of the product, it is more suitable for occasions of armoured thermal resistance and installation is inconvenient, suitable for temperature measurement in -50~400 DEG C for.
