薄膜铂热电阻WZPK-134U 供应
产品概述
薄膜铂热电阻WZPK-134U是一种高精度温度传感器,采用先进的铠装薄膜技术设计,适用于工业自动化、环保监测、医疗设备等领域。其核心测温元件由陶瓷基片和铂薄膜组成,通过激光喷溅工艺实现高稳定性与快速响应,可精确测量-200℃至+800℃范围内的温度。产品具有直径小、弯曲灵活的特点,能够适应装配式热电阻无法安装的复杂场景,尤其适合管道狭窄或高振动环境。
技术特点
WZPK-134U采用不锈钢保护管与高密度氧化镁绝缘材料,兼具抗污染和机械强度高的优势。铂薄膜元件通过激光调阻工艺确保电阻值一致性,温度系数偏差极小(α=0.003851±0.000006),热响应时间短(T0.5≤0.3秒)。引线材料可选镍镀金或纯钯,保证信号传输稳定性。产品在15-35℃环境下绝缘电阻≥100MΩ,自热影响低(≤0.3℃),长期使用性能稳定。
应用场景
广泛应用于石油化工、电力能源、食品加工等行业的温度监控系统,也可集成至显示仪表、记录仪或自动化控制设备。其紧凑结构和抗震设计特别适合汽车工业(如发动机油温监测)、医疗设备温控及环保工程中的气体排放监测。
核心优势
- 精确测温:铂薄膜元件提供高线性输出,减少动态误差。
- 耐用设计:不锈钢护套与陶瓷涂层增强抗压与绝缘性能。
- 灵活安装:支持无固定装置、卡套螺纹或法兰等多种安装方式。
Product Introduction
The WZPK-134U Thin-Film Platinum RTD is a precision temperature sensor designed for industrial automation, environmental monitoring, and medical equipment. Its core sensing element combines ceramic substrate with platinum film via advanced laser sputtering technology, enabling stable performance and fast response within a range of -200°C to +800°C. The compact and flexible design allows installation in confined or high-vibration spaces where traditional RTDs are unsuitable.
Key Features
Stainless steel sheath and magnesium oxide insulation ensure resistance to contamination and mechanical stress. The laser-trimmed platinum film achieves minimal deviation in temperature coefficient (α=0.003851±0.000006) and rapid thermal response (T0.5≤0.3s). Options for gold-plated nickel or pure palladium leads enhance signal reliability. Insulation resistance exceeds 100MΩ at 15-35°C, with low self-heating effect (≤0.3°C).
Applications
Ideal for temperature monitoring in petrochemicals, power plants, and food processing. Its robust construction suits automotive systems (e.g., engine oil temperature) and medical device controls, while the anti-vibration design benefits environmental gas emission analysis.
Advantages
- Accuracy: Linear output minimizes dynamic errors.
- Durability: Stainless steel and ceramic layers improve pressure resistance.
- Adaptability: Supports flange, threaded, or non-fixed installations.
