WZPK-274S Platinum Resistance Temperature Detector Product Introduction
The WZPK-274S Platinum Resistance Temperature Detector is a precision temperature measurement component specifically designed for industrial applications. Utilizing high-purity platinum wire as the core sensing element and optimized structural design, it is widely applicable for temperature monitoring in HVAC systems, food processing equipment, pharmaceutical manufacturing facilities, and chemical reaction vessels. Through scientifically optimized thermal response characteristics, the product ensures stable and reliable data transmission in complex working conditions, providing accurate temperature feedback for process control.
Featuring a 316L stainless steel protective sheath, this sensor demonstrates exceptional mechanical strength and corrosion resistance, capable of withstanding prolonged exposure to high-temperature and high-pressure environments. The internal high-purity magnesium oxide insulation effectively enhances vibration resistance and thermal conductivity. The fully welded hermetic sealing process achieves IP65 protection rating, effectively preventing moisture and dust ingress. Multiple installation interfaces are available, including standard threaded specifications such as M12×1.5 and M16×1.5, with optional flange mounting configurations for flexible integration with various equipment structures.
Technical specifications include a temperature measurement range from -50℃ to +300℃, suitable for most industrial requirements. The three-wire connection system significantly reduces the impact of lead resistance on measurement accuracy. Standard high-temperature fluoropolymer insulated cables can withstand continuous operation in 200℃ environments. Rigorous aging screening tests ensure long-term stability with annual drift less than 0.1℃ in operating temperatures between -20℃ and +150℃. The specially designed tapered probe structure improves medium contact efficiency, achieving typical thermal response time τ0.5≤8 seconds in liquid media.
For specialized applications, explosion-proof configurations are available. Customization options include probe lengths ranging from 50mm to 1000mm and extension cables up to 20 meters. Each unit undergoes multi-point temperature calibration prior to delivery to ensure compliance with specified accuracy requirements, supported by comprehensive quality management protocols throughout the manufacturing process.
