English Introduction
The MWFT-2 thin-film platinum resistance thermometer is an advanced temperature measurement sensor widely used for temperature monitoring and control in industrial production processes. This product utilizes a thin-film platinum resistor as the temperature-sensing element, which is based on a silicon substrate and manufactured through advanced sputtering, photolithography, and laser trimming processes. This design endows the MWFT-2 with characteristics such as full solid-state structure, ultra-compact size, fast response, and high reliability.
The measurement range of the MWFT-2 is from -79°C to 500°C, with a nominal resistance of 100Ω at 0°C and a precision grade of B. The relationship between its resistance and temperature conforms to the general formula of platinum resistance thermometers, ensuring high-precision temperature measurement. The protection tube of the MWFT-2 is made from different materials according to the conditions of the measured medium and the measurement temperature, featuring good temperature resistance, corrosion resistance, and airtightness. The junction box is made of aluminum alloy, offering certain mechanical strength and sealing performance.
The MWFT-2 thin-film platinum resistance thermometer is suitable for measuring the temperature of liquids, vapors, gases, and fixed surfaces. It is widely used in various fields such as chemical industry, pharmaceuticals, food processing, and scientific research equipment. Its compact size and flexible installation options make it ideal for use in environments with limited space.

熱電阻是中低溫區(qū)常用的一種溫度檢測器。它的主要特點是測量精度高，性能穩(wěn)定。其中鉑熱電阻的測量精確度是高的，它不僅廣泛應(yīng)用于工業(yè)測溫，而且被制成標(biāo)準(zhǔn)的基準(zhǔn)儀。
主要特點
簧式感溫元件，抗振性能好；
•測溫精度高；
•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通過引線傳遞到計算機(jī)控制裝置或者其它二次儀表上。
