English Introduction
The WZP2 - 631B thermoresistance is a high - quality temperature - sensing element specifically designed for temperature measurement in power stations. It utilizes high - purity platinum wire as the temperature - sensing element, which boasts remarkable stability and can maintain precise temperature - measuring performance over the long term in the complex operating environment of power stations. The typical measuring range of this thermoresistance is from - 200℃ to + 850℃, capable of meeting the temperature - monitoring requirements of various equipment under different operating conditions in a power station. It can accurately capture and provide real - time feedback on temperature changes in key parts such as generator windings, transformer oil temperature, and turbine bearings.
In terms of structural design, the protective sheath of the WZP2 - 631B thermoresistance is made of robust stainless steel, which has been finely processed to offer excellent corrosion and wear resistance. It can effectively protect the thermoresistance from potential damage caused by factors such as humidity, oil contamination, and mechanical impact in the power station environment. The lead - out part of the thermoresistance adopts reliable insulation and sealing measures to ensure the stability and accuracy of the electrical signal transmission, avoiding measurement errors due to external interference.
The installation of this thermoresistance is highly flexible. Depending on the specific structure and installation space of the power station equipment, various fixing methods such as threaded connection and flange installation can be chosen to quickly and accurately install it at the temperature - measuring point. Moreover, the thermoresistance has a fast response speed. It can swiftly react to temperature changes and output the corresponding electrical signal, providing timely and accurate temperature data for the automation control system of the power station. This helps to ensure the safe, efficient, and stable operation of the power station. The WZP2 - 631B thermoresistance is an indispensable and reliable partner in the temperature - monitoring process of power stations.
