Key Features
The WZP2-221B thermocouple features a threaded installation design (M27×2) and a stainless steel junction box for robust performance in harsh environments. Its dual-wire platinum sensing element (Pt100) delivers high repeatability across a broad range of -200°C to 420°C, suitable for pipelines, reactors, and other industrial equipment. The splash-proof construction enhances durability, while the modular assembly allows easy maintenance. Compatible with most temperature controllers, it provides reliable data for process automation without requiring complex calibration. The standardized interface ensures seamless integration with existing systems.118
應(yīng)用場(chǎng)景
該熱電阻廣泛用于測(cè)量蒸汽管道、鍋爐設(shè)備及化工反應(yīng)釜中的介質(zhì)溫度。其固定螺紋設(shè)計(jì)可承受10MPa公稱壓力，適合高壓環(huán)境；感溫元件采用進(jìn)口薄膜電阻技術(shù)，確保長(zhǎng)期使用后仍保持穩(wěn)定輸出。用戶可根據(jù)需求選擇不同插入深度（如150mm或300mm），適配多樣化安裝條件。典型應(yīng)用包括食品加工設(shè)備的溫控監(jiān)測(cè)、冶金行業(yè)熔爐溫度追蹤，以及環(huán)保領(lǐng)域的氣體排放監(jiān)控。產(chǎn)品無(wú)活動(dòng)部件，減少磨損風(fēng)險(xiǎn)，適合連續(xù)運(yùn)行的工業(yè)場(chǎng)景。3616
Technical Specifications
With a thermal response time (T0.5) under 90 seconds, the WZP2-221B minimizes lag in dynamic temperature measurement. The hermetically sealed sensing element prevents moisture ingress, and the 316L stainless steel sheath resists corrosion from acids or alkalis. Standard models include two-wire configuration for basic setups, while custom options support three-wire compensation to reduce lead resistance errors. Its compact dimensions (e.g., total length 550mm) facilitate installation in space-constrained areas. Operating humidity ranges up to 80% non-condensing.91521

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(kāi)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(guò)引線傳遞到計(jì)算機(jī)控制裝置或者其它二次儀表上。
