室內(nèi)用雙支鉑熱電阻WRN2-740 供應(yīng)
產(chǎn)品概述
室內(nèi)用雙支鉑熱電阻WRN2-740是一款專為工業(yè)溫度測量設(shè)計(jì)的精密傳感器，采用優(yōu)質(zhì)鉑絲作為感溫元件，通過雙支獨(dú)立繞組結(jié)構(gòu)實(shí)現(xiàn)兩組同步溫度信號(hào)輸出。該產(chǎn)品適用于需要多點(diǎn)監(jiān)測或冗余備份的室內(nèi)環(huán)境，如實(shí)驗(yàn)室恒溫系統(tǒng)、暖通空調(diào)設(shè)備、制藥車間等場景，能夠穩(wěn)定測量-200℃至500℃范圍內(nèi)的介質(zhì)溫度，確保數(shù)據(jù)可靠性與系統(tǒng)安全性。815
核心技術(shù)特點(diǎn)
WRN2-740采用全密封不銹鋼保護(hù)管設(shè)計(jì)（材質(zhì)1Cr18Ni9Ti），具備優(yōu)異的防潮、防腐蝕性能，特別適合長期在潮濕或含輕微腐蝕性氣體的室內(nèi)環(huán)境中使用。雙支獨(dú)立Pt100元件通過先進(jìn)繞制工藝實(shí)現(xiàn)±0.3℃的高精度，熱響應(yīng)時(shí)間≤3秒，能快速捕捉溫度變化。獨(dú)特的抗電磁干擾屏蔽層設(shè)計(jì)，有效避免信號(hào)傳輸過程中的噪聲干擾，配合三線制接線方式可消除導(dǎo)線電阻誤差。產(chǎn)品機(jī)械強(qiáng)度達(dá)10MPa耐壓，使用壽命超過常規(guī)單支熱電阻30%以上。5610
應(yīng)用場景與優(yōu)勢
在發(fā)電機(jī)組軸承監(jiān)測、食品加工生產(chǎn)線、精密儀器溫控系統(tǒng)等領(lǐng)域，WRN2-740可同時(shí)連接兩套顯示或控制儀表，實(shí)現(xiàn)溫度數(shù)據(jù)的交叉驗(yàn)證與系統(tǒng)冗余。其緊湊型結(jié)構(gòu)（總長可按需定制5000mm/7000mm）配合φ5.4mm柔性引線，便于在狹窄空間安裝布線。與同類產(chǎn)品相比，該型號(hào)采用進(jìn)口微型鉑絲元件和聚四氟乙烯護(hù)套電纜，在30-50℃油浸或高濕環(huán)境下仍能保持穩(wěn)定性能，解決傳統(tǒng)熱電阻引線易老化開裂的問題。91417
定制化服務(wù)說明
客戶可根據(jù)實(shí)際需求選擇不同插入深度（35mm標(biāo)準(zhǔn)探頭長度）、接線盒防護(hù)等級(jí)（防水/防濺式）及電纜長度規(guī)格。產(chǎn)品交付前均經(jīng)過72小時(shí)老化測試和-50℃~300℃循環(huán)沖擊驗(yàn)證，確保各批次性能一致性。我們提供技術(shù)咨詢、安裝指導(dǎo)等配套服務(wù)，幫助用戶優(yōu)化測溫點(diǎn)布置方案，提升系統(tǒng)整體測溫效率。11120

Product Overview
The WRN2-740 indoor dual-element platinum RTD is a precision temperature sensor designed for industrial applications. Featuring high-purity platinum wire sensing elements in dual independent windings, it provides two synchronous temperature outputs for redundant monitoring. Ideal for laboratories, HVAC systems, and pharmaceutical facilities, this device delivers stable measurements from -200℃ to 500℃ with enhanced data reliability. 815
Technical Highlights
Constructed with hermetic 1Cr18Ni9Ti stainless steel sheath, the WRN2-740 exhibits exceptional moisture and corrosion resistance for indoor harsh environments. Its dual Pt100 elements achieve ±0.3℃ accuracy via advanced winding technology, with ≤3s thermal response time. The anti-interference shielding layer and 3-wire configuration eliminate signal noise and lead resistance errors. With 10MPa pressure tolerance and 30% longer lifespan than single-element models, it ensures durable performance. 5610
Applications & Benefits
In power plant bearing monitoring, food processing lines, and precision instrument temperature control, the WRN2-740 enables cross-validation by connecting to dual displays/controllers simultaneously. The compact design (customizable 5000mm/7000mm length) with flexible φ5.4mm cables facilitates installation in confined spaces. Compared to conventional RTDs, its imported micro platinum elements and PTFE-jacketed cables maintain stability in 30-50℃ oil-immersion or high-humidity conditions, preventing cable degradation. 91417
Customization Options
Customers can select probe lengths (35mm standard), junction box protection ratings (waterproof/splash-proof), and cable lengths. Each unit undergoes 72-hour aging tests and -50℃~300℃ thermal cycling for performance consistency. We provide technical consultation and installation guidance to optimize temperature measurement layouts. 11120
