,调理器和显现仪表等配套操纵,构成进程节制体系,用以间接丈量或节制各类出产进程中-200℃-500℃规模内的液体,蒸汽和蔼体介质和固体外表的温度。
概况先容：
WZP-121香港王中王资料 ，产业用香港王中王资料 分铂香港王中王资料 和铜香港王中王资料 两大类。香港王中王资料 是操纵物资在温度变更时本身电阻也跟着产生变更的特征来丈量温度的。香港王中王资料 的受热局部（感温元件）是用细金属丝均匀地双绕在绝缘资料制成的骨架上。当被测介质中有温度梯度存在时，所测得的温度是感温元件地址规模内介质层中的均匀温度。拆卸式香港王中王资料 首要由接线盒、掩护管、接线端子、绝缘套管和感温元件构成，并配以各类装配牢固装配。WZP型铂电阻的感温元件是一个铂丝绕组，双支铂电阻首要用于须要用二次显现、记实或调理仪同时检测统一地址温度的场所。WZC型铜电阻的感温元件是一个铜丝绕组。

受热后的金属丝电阻跟着温度的变更而变更，其香港王中王资料
值R(t)与其所处温度t的干系可表现为： R(t)=Ro(1+At+Bt2+------)按测得的电阻值查响应分度号表便可得出被测温度值t。或由显现仪表间接读出。
Industrial thermal resistance contains two categories, Pt thermal reistance and Copper thermal ressistance.
Thermal resistance is used to measure temperature on the basis of the property that substances’own resistance varies with the temperature. The part of the thermal resistance that is heated (temperataure-sensing element) is made by dual winding of fine wires around the frame made of insulation materials. When there is temperature gradient in the mediums to be measured, the measured temperature is the average temperature in the dielectric layer within the range where the temperature-sensing element is placed.Packaged thermal resistance consists of connection box, protectin tube, connection terminal, insulating sleeve and various fixed devices.WZP Pt resistance’s temperature-sensing element is a Pt wire winding. Double platinum resistance mainly is used fou such situation where it is required to use secondary display instrument, recorder and accommodometer to simultaneously detect the temperature of the same place. WZC copper resistance’s temperature-snesing element is a copper wire winding.
Temperature measurement principle of thermal resistance
The resistance of the metal wire that has been heated varies with the termperature, and the relation between the thermal resistance value and the temperature it is at can be expressed as R(t)=Ro((1+At+Bt2+------)According to the resistance value that is measured to refer to corresponding graduation mark, the temperature t that is measured can be come out, or read it directly from the indicating instrument.
