薄膜铂热电阻WZPK-304U 厂家
产品概述
WZPK-304U铠装薄膜铂热电阻是一种高精度温度传感器,专为复杂安装环境设计。其直径小巧且具备优异的弯曲性能,适用于传统装配式铂热电阻无法安装的狭窄或特殊场合。该产品采用不锈钢保护管结构,内部填充高密度氧化物绝缘材料,兼具抗机械冲击与耐腐蚀特性,可在恶劣工业环境中稳定工作。薄膜铂电阻元件通过先进的激光喷溅工艺制成,响应速度快,长期稳定性突出,能够为温度监测系统提供可靠数据支持。测温范围为-200℃至+800℃,适用于液体、气体及固体表面温度的精确测量。
Technical Features
The WZPK-304U armored thin-film platinum RTD is engineered for high-precision temperature measurement with compact dimensions (typical outer diameter of 4mm) and flexible installation. Its stainless-steel sheath integrates a dense oxide insulation layer, ensuring resistance to vibration and chemical corrosion in demanding industrial applications. The thin-film sensing element, fabricated via laser sputtering technology, delivers rapid thermal response (T0.5≤5s) and minimal self-heating effect (<0.3℃ at 5mA). The sensor supports multiple installation options including movable threaded connections, adapting to diverse pipeline or equipment configurations. With a standard Pt100 output, it seamlessly interfaces with displays, recorders, and control systems for real-time temperature monitoring across -200℃ to +800℃.
应用场景
该产品广泛应用于石油化工、电力能源、冶金等行业的流程控制领域。在管道密集区域或需要快速温度反馈的场合(如反应釜、换热设备),其铠装结构可有效抵御高压和介质侵蚀。同时,在环保监测与实验室研究中,凭借低误差特性(±(0.15+0.02|t|)℃),可为数据采集提供高重复性测量结果。
Application Scenarios
Ideal for process control in chemical plants, power stations, and metallurgical facilities, the WZPK-304U excels in confined spaces requiring robust performance. Its design addresses challenges such as high-pressure piping systems and corrosive media handling. The sensor also serves critical roles in environmental monitoring and R&D laboratories, where consistent accuracy (±0.3+0.005|t|℃ for B-grade) ensures reliable experimental data acquisition under dynamic thermal conditions.
设计优势
产品采用模块化接线盒设计,提供防水、防溅等不同防护等级选项,适配户外或潮湿工况。镍镀金引线结构优化了信号传输稳定性,而陶瓷基薄膜技术则显著提升耐温极限与抗震性能,满足长期免维护需求。
Design Advantages
Modular junction box configurations accommodate diverse environmental requirements, from splash-proof to submersible applications. Gold-plated nickel leads enhance signal integrity, while the ceramic-backed thin-film technology extends operational lifespan under thermal cycling and mechanical stress, reducing maintenance intervals.
