【Product Introduction in English】
The WZPM-201 Specialized Thermistor for Power Plants is engineered for temperature monitoring in complex operational environments of thermal, hydroelectric and renewable energy facilities. Featuring modular construction with high-stability platinum resistance elements, this device delivers precise temperature detection across a broad operational range from -50℃ to +500℃, maintaining basic accuracy within ±(0.15+0.002|t|)℃ to ensure reliable monitoring of critical power generation equipment.
The sensor core adopts dual-sealing technology, integrating the sensing element with 316L stainless steel protective tube through vacuum sintering process. This robust construction effectively resists moisture ingress and chemical penetration. Surface passivation treatment enhances durability in challenging environments containing sulfurous flue gas and weak acidic condensate. With IP67 protection rating and vibration resistance compliant with EN 60068-2-6 specifications, the device maintains stable performance under intense turbine vibration conditions.
The flame-retardant engineering plastic junction box contains dual-channel terminals supporting 3-wire compensation connection, effectively eliminating measurement deviations caused by lead resistance. Multiple installation options including flange mounting, threaded connection and weldable fittings are available, compatible with DN15-DN50 piping systems. Built-in electromagnetic interference shielding ensures stable signal transmission in high-voltage equipment clusters.
Proven in practical applications, this model has been successfully deployed in boiler superheater monitoring, turbine bearing temperature protection, and transformer oil temperature detection. Optimized thermocouple configuration and signal processing algorithms reduce response time to 70% of conventional products. Maintenance teams can utilize the integrated diagnostic system to monitor sensor health status in real time, significantly reducing unplanned downtime risks. The product s adaptable design accommodates both new plant installations and legacy system upgrades, providing cost-effective temperature monitoring solutions for global power infrastructure.
