Product Introduction
The MWFT-1 thin-film platinum RTD is a precision temperature sensor utilizing advanced thin-film deposition technology. Designed for industrial applications, it delivers accurate measurements (-79°C to 600°C) for liquids, vapors, and gases with rapid response and robust durability. Its compact construction integrates seamlessly with display instruments, serving energy, chemical processing, and manufacturing sectors. 19
Key Features
A silicon-substrate platinum film sensing element, fabricated via sputtering and laser trimming, ensures miniaturization and stability. With Pt100 classification (100Ω at 0°C, Class B accuracy), it maintains consistent temperature-resistance linearity. Customizable sheath materials (e.g., stainless steel) and junction boxes (explosion-proof/waterproof variants) adapt to harsh environments. 38
Technical Highlights
The thin-film design reduces thermal mass, achieving 50% faster response (T0.5) than wire-wound counterparts. Low insertion depth requirements and 100MΩ insulation resistance (at 10-100V) enhance installation flexibility and signal integrity. The 2mA excitation current minimizes self-heating errors for reliable data acquisition. 710
Applications
Ideal for dynamic temperature monitoring in pipelines, reactor vessels, power plant equipment, and HVAC systems. Modular components facilitate maintenance, while OEM customization (e.g., sheath length adaptation) addresses specialized needs. 615

熱電阻是中低溫區(qū)常用的一種溫度檢測(cè)器。它的主要特點(diǎn)是測(cè)量精度高,性能穩(wěn)定。其中鉑熱電阻的測(cè)量精確度是高的,它不僅廣泛應(yīng)用于工業(yè)測(cè)溫,而且被制成標(biāo)準(zhǔn)的基準(zhǔn)儀。
主要特點(diǎn)
簧式感溫元件,抗振性能好;
•測(cè)溫精度高;
•機(jī)械強(qiáng)度高,耐高溫耐壓性能好;
•進(jìn)口薄膜電阻元件,性能可靠穩(wěn)定。
工作原理
熱電阻的測(cè)溫原理是基于導(dǎo)體或半導(dǎo)體的電阻值隨著溫度的變化而變化的特性。熱電阻大都由純金屬材料制成,目前應(yīng)用多的是鉑和銅,現(xiàn)在已開始采用鎳、錳和銠等材料制造熱電阻。熱電阻通常需要把電阻信號(hào)通過引線傳遞到計(jì)算機(jī)控制裝置或者其它二次儀表上。
