Outlet thermal resistance of Temperature Transmitter is also called socket platinum thermal resistance. Socket type thermal resistance temperature measurement is based on the property that metal conductor resistance value increased with temperature ,Thermal resistance is mostly made of pure metal material, currently the most widely used are platinum and copper ,which are connector with form and convenient installation. Socket platinum thermal resistance element is used in miniature ceramic pipe, hole arranged around the platinum thermal resistance wire coil made from prepared temperature sensing element, a temperature sensing element made fairly small (diameter can be done with 1.6 ~ 1.2mm) it is made of a variety of micro temperature sensor probe. The connector form, convenient installation. Suitable for liquid, gas and solid surface temperature range of -200-+450 ℃ measurement.

260, 270, 280 series of socket type thermal resistance accord to the new standard of JB/T8622-1997 in china. Its working principle is under the action of temperature, the resistance value of the platinum resistance wire changes with temperature. The relationship between temperature and resistance is close to a linear relationship ,the deviation is minimum, and with the increase of time, deviation can be neglected and electrical performance is stable. The series products are provided with small structure, wide range of use, good reliability, short thermal response time etc., also can be formed to many varieties, specifications for petroleum, chemical, power, metallurgy, light industry, food, textile, medical, scientific research, agricultural and mechanical industry to provide a new generation of high-quality products.
