Product Introduction (英文部分)
The WZP2-130B industrial RTD is a dual-element platinum resistance thermometer designed for reliable temperature measurement in harsh environments. With a standard Pt100 sensing element, it delivers accurate readings across -200°C to +420°C range. The modular assembly structure features replaceable components including stainless steel junction boxes (splash-proof or waterproof) and oxidation-resistant protection tubes, ensuring long-term stability in petrochemical, power generation and metallurgical applications. Its twin independent channels allow simultaneous data transmission to multiple control systems.122
Key Features
This RTD utilizes thin-film platinum technology with class B accuracy (±0.3°C or ±0.005|t|). The hermetically sealed sensing assembly exhibits >100MΩ insulation resistance at 100VDC. Standard 16mm OD protection tubes withstand 1.5x rated pressure, while the 3-wire configuration eliminates lead resistance errors. Customizable insertion lengths (L=XXmm) and process connections (NPT/G螺紋) adapt to various installation requirements. The 5mA current limit ensures minimal self-heating effect during continuous operation.121924
Typical Applications
Ideal for dual-redundancy temperature monitoring in turbines, reactors and pipelines. Compatible with most PLC/DCS systems through direct resistance output or via temperature transmitters. Recommended for steam lines (-30~420°C), hydraulic oil tanks (-50~150°C) and solid surface measurements. Installation notes: For pipe mounting, insert length should reach centerline; avoid excessive vibration locations.41527

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(diǎn)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(diǎn)
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(jì)算機(jī)控制裝置或者其它二次儀表上。
