產(chǎn)品英文介紹：
The WZP-430B industrial temperature sensor is a precision measurement device specifically engineered for power plant systems. Utilizing platinum resistance temperature detection technology, it delivers reliable performance in critical applications including steam turbine monitoring and generator temperature tracking within thermal and nuclear power facilities.
Constructed with 316L stainless steel housing through integral welding process, the sensor features a specially polished surface to minimize medium adhesion. The core component integrates high-purity platinum sensing wire with dual-layer magnesium oxide insulation, achieving linearity deviation within ±0.5% across a broad operational range from -200℃ to +650℃. Modular design provides flexible installation options with adjustable threaded connections (M27×2/G1") and reinforced junction boxes. Quad-core shielded cables with high-temperature silicone sheathing ensure 20kV·mm insulation strength for safe operation in high-voltage environments.
Enhanced electromagnetic compatibility is achieved through symmetrical bridge circuit design, effectively suppressing common-mode interference. Explosion-proof terminal chambers and vibration-resistant construction make it particularly suitable for generator bearing temperature monitoring. Multiple configurations including straight, angular and swivel adapters are available to accommodate spatial constraints. Laboratory aging tests demonstrate less than 0.05% resistance drift after 2000-hour continuous operation, ensuring long-term stability for plant equipment condition monitoring.
