英文介绍(Product Overview)
The WZPK-205S armored platinum resistance thermometer is a robust temperature sensor designed for industrial applications. Its stainless steel sheath and compact diameter (as small as φ3mm) allow flexible installation in confined spaces, while the high-density oxide insulation ensures resistance to contamination and mechanical stress. The sensor operates within a wide range of -200°C to 500°C, delivering fast thermal response and stable signals to connected devices like displays or data loggers. The fixed threaded mounting (indicated by "2" in the model number) enhances stability in vibrating environments.916
Key Features
The WZPK-205S features a durable construction with optional single or dual-element designs (dual-element uses 3-wire configuration). Its accuracy meets practical demands, with Class A deviation at ±(0.15+0.002|t|)°C. The sensor s insulation resistance exceeds 100MΩ under standard conditions, and its pressure resistance withstands 1.5 times the rated pressure. Suitable for harsh conditions, it is widely used in pipelines, reactors, and other equipment requiring reliable temperature monitoring. The bend-resistant design ensures longevity, with a recommended minimum bending radius of 100mm at the sensing end.131722
应用场景(Applications)
WZPK-205S广泛应用于化工、石油、电力及食品加工等行业,适用于反应釜、蒸汽管道、换热器等设备的温度监测。其抗震动特性使其成为旋转机械或高流速介质的理想选择。此外,防水式接线盒型号(如WZPK-235S)可应对潮湿或户外环境。客户可根据实际需求选择不同外径、长度或安装方式(如法兰固定)。11520
注意事项(Notes)
安装时需避免在测量端150mm范围内弯曲,以防损坏内部元件。连接导线建议采用屏蔽铜线,截面积不小于1.5mm²,以减少信号干扰。对于动态温度场测量,需选择合适的热响应时间型号以确保数据准确性。长期使用后建议定期检查绝缘性能。272830
