WRE-240A Indoor Dual-Prong Platinum Thermal Resistor is a high-precision temperature sensor designed for industrial and laboratory environments. Featuring a platinum sensing element with dual-wire configuration, it ensures stable and reliable temperature measurement within a broad range of -200℃ to 500℃. The compact design allows for easy installation, while dual independent outputs enable simultaneous multi-point monitoring or redundant backup, making it ideal for applications demanding data consistency and reliability.
核心特性
WRE-240A的感溫元件采用均勻繞制工藝，確保溫度梯度下的測(cè)量精度，輸出信號(hào)線性度高。產(chǎn)品具備防潮、防震設(shè)計(jì)，適應(yīng)復(fù)雜室內(nèi)環(huán)境；外殼采用耐腐蝕材質(zhì)，延長(zhǎng)使用壽命。與顯示儀表配套使用時(shí)，需連接補(bǔ)償導(dǎo)線，兼容主流工業(yè)控制系統(tǒng)，便于集成。
The WRE-240A utilizes precision-wound platinum elements to deliver high linearity and accuracy even under temperature gradients. Its robust construction includes moisture-proof and shock-resistant features, suitable for challenging indoor conditions. The corrosion-resistant housing enhances durability. When paired with display instruments via compensation leads, it seamlessly integrates with industrial control systems.
應(yīng)用場(chǎng)景
廣泛應(yīng)用于暖通空調(diào)、電力設(shè)備、化工反應(yīng)器等需要實(shí)時(shí)溫度監(jiān)控的領(lǐng)域。雙支設(shè)計(jì)可分別接入不同儀表，實(shí)現(xiàn)數(shù)據(jù)比對(duì)或故障冗余，提升系統(tǒng)可靠性。
Common applications include HVAC systems, power equipment, and chemical reactors where real-time temperature monitoring is critical. The dual-prong design supports data validation through separate instrument connections, enhancing system fault tolerance.
技術(shù)參數(shù)
基本誤差控制在合理范圍內(nèi)，環(huán)境適應(yīng)性符合常規(guī)工業(yè)要求。負(fù)載電阻支持三線制或二線制接線方式，工作電壓兼容標(biāo)準(zhǔn)工業(yè)電源。
The product maintains minimal baseline error and adapts to standard industrial environments. It supports both 3-wire and 2-wire connections, with voltage compatibility across common industrial power supplies.
服務(wù)支持
提供定制化選項(xiàng)，如保護(hù)管材質(zhì)與長(zhǎng)度調(diào)整，滿(mǎn)足不同安裝需求。
Customization options include protective tube materials and lengths to accommodate diverse installation requirements.
