WZPM-201 thermal resistance is a precision instrument specially designed for measuring the surface temperature of objects. It is highly praised by power plant users for its outstanding performance under harsh conditions. This article will explore the performance of WZPM-201 thermal resistance in the extreme environment of steam turbines and explain the special protection measures taken to ensure its long-term stable operation.

The end surface thermal resistance WZPM-201 adopts the process of sintering the platinum resistance element in the polytetrafluoroethylene cable outer casing to ensure the reliable isolation of the element from the outside world. Its design makes the resistance element close to the surface of the object to be measured. Compared with the traditional axial thermal resistance, WZPM-201 can more quickly and accurately reflect the actual temperature of the measured end surface, especially suitable for measuring the surface temperature of motor bearings, power plant steam turbines, molds or other objects.

The WZPM-201 thermal resistance was designed with full consideration of the particularity of the turbine operating environment. The materials and structural design used can withstand high temperatures of up to hundreds of degrees Celsius and pressures of several megapascals, and have a certain degree of vibration resistance. At high temperatures, the stability and accuracy of the RTD are optimized to ensure reliable data even under extreme conditions.

However, any device exposed to high temperature and high pressure for a long time will face the risk of performance degradation. In addition, vibration may cause the RTD to have poor contact with the measurement surface, affecting the measurement accuracy. Therefore, the WZPM-201 RTD is designed with additional protection measures to enhance its stability and life in harsh environments.

Special protection measures:

The protection tube and junction box are made of high-quality high-temperature resistant materials and alloys to resist the erosion of high temperature and high pressure.

The use of high-performance sealing materials and processes ensures that the RTD can still maintain good airtightness and waterproofness in high-pressure environments, preventing moisture and impurities from entering and affecting measurement accuracy.

The physical state and electrical performance of the RTD are regularly checked to ensure its accuracy.

Multiple RTDs are installed at key measurement points to achieve redundant measurement, so that the system can still obtain accurate temperature data even if a single RTD fails.

With its unique design and material selection, the WZPM-201 RTD has demonstrated excellent performance in the harsh environment of high temperature, high pressure and vibration of the turbine. By implementing a series of special protection measures, not only its stability and durability are enhanced, but also accurate temperature data can be obtained by the turbine control system, which is essential for the normal operation and safety of the equipment. With the continuous advancement of technology, the performance and protection measures of WZPM-201 thermal resistances will be further optimized, providing stronger support for the sustainable development of the energy industry.
