WSSP-481雙金屬溫度計產(chǎn)品介紹
中文介紹
WSSP-481雙金屬溫度計是一種用于測量中低溫的現(xiàn)場檢測儀表，適用于多種工業(yè)和商業(yè)場景。它可以直接測量生產(chǎn)過程中-80℃至+500℃范圍內(nèi)的液體、蒸汽和氣體等介質(zhì)的溫度。
該溫度計采用全不銹鋼一體化設(shè)計，保護管、節(jié)頭、鎖緊螺栓等均使用1Cr18Ni9Ti材料，表殼經(jīng)過黑色電泳處理，具有良好的防水防腐性能。其測量原理基于雙金屬片的熱膨脹特性，一端受熱膨脹時帶動指針旋轉(zhuǎn)，從而在表盤上顯示溫度。
WSSP-481還具備遠傳功能，可輸出PT100熱電阻信號或4-20mA電流信號，滿足遠距離傳輸需求。其測溫范圍為-40℃至600℃，精度等級為1.5級，響應時間不超過60秒。此外，該溫度計的探頭耐壓可達6MPa，防護等級為IP55，適用于多種惡劣環(huán)境。
英文 Introduction
The WSSP-481 bimetallic thermometer is a field detection instrument used for measuring medium and low temperatures, suitable for various industrial and commercial applications. It can directly measure the temperature of liquids, vapors, and gases in the range of -80℃ to +500℃.
This thermometer features an integrated stainless steel design. The protective tube, joints, and fastening bolts are all made of 1Cr18Ni9Ti material, and the casing is treated with black electrophoretic coating, providing excellent waterproof and corrosion-resistant properties. Based on the thermal expansion principle of bimetallic strips, the temperature is indicated on the dial as one end expands with heat, driving the pointer to rotate.
The WSSP-481 also has remote transmission capabilities, offering PT100 resistance temperature detector (RTD) signals or 4-20mA current output to meet long-distance transmission requirements. With a measurement range of -40℃ to 600℃ and an accuracy class of 1.5, it has a response time of no more than 60 seconds. Additionally, the thermometer s probe can withstand pressure up to 6MPa, and it has an IP55 protection rating, making it suitable for various harsh environments.

工作原理
雙金屬溫度計的工作原理是利用二種不同溫度膨脹系數(shù)的金屬，為提高測溫靈敏度，通常將金屬片制成螺旋卷形狀，當多層金屬片的溫度改變時，各層金屬膨脹或收縮量不等，使得螺旋卷卷起或松開。
由于螺旋卷的一端固定而另一端和一可以自由轉(zhuǎn)動的指針相連，因此，當雙金屬片感受到溫度變化時，指針即可在一圓形分度標尺上指示出溫度來。這種儀表的測溫范圍是200~650℃，允許誤差均為標尺兩程的1%左右。
概述
雙金屬溫度計的英文名稱是bimetal thermometer;bimetallic thermometer，是一種適合測量中低溫的現(xiàn)場檢測儀表，可直接測量各種生產(chǎn)過程中的液體、蒸汽和氣體介質(zhì)溫度。
雙金屬溫度計主要的元件是一個用兩種或多種金屬片疊壓在一起組成的多層金屬片，利用兩種不同金屬在溫度改變時膨脹程度不同的原理工作的。是基于繞制成環(huán)性彎曲狀的雙金屬片組成。一端受熱膨脹時，帶動指針旋轉(zhuǎn)，工作儀表便顯示出熱電勢所應的溫度值。
