【English Product Introduction】
The WZP-221B industrial thermal resistor is a precision temperature measurement solution engineered for power plant applications and demanding industrial environments. Featuring a stainless steel sheath combined with alumina insulation, this device delivers reliable performance across an operational range of -50℃ to +450℃, making it ideal for monitoring critical thermal parameters in boiler systems, steam lines, and heat exchange equipment.
Constructed with platinum resistance elements, the sensor achieves ±0.5% measurement accuracy through advanced electrode encapsulation technology. The reinforced mechanical structure incorporates vibration dampening and electromagnetic shielding, specifically addressing the challenges of high-vibration turbine halls and electromagnetic interference zones in power generation facilities. IP65-rated housing provides robust protection against airborne particulates and pressurized water jets, ensuring durability in humid substation environments and dusty equipment rooms.
Standardized electrical interfaces enable direct compatibility with industrial control systems, while the dual-orientation mounting bracket accommodates both axial and radial installation configurations. Field-serviceable components allow for rapid maintenance without full system shutdown. Customizable probe lengths (50mm-1500mm) and cable specifications are available to match specific application requirements, with production lead times maintained at 7-15 business days for most standard configurations.
