傳感元件由特殊合金材料復合制成，在-20℃至500℃量程范圍內(nèi)保持穩(wěn)定的線性響應(yīng)特性。產(chǎn)品內(nèi)置可調(diào)節(jié)式電接點系統(tǒng)，用戶可通過旋鈕精確設(shè)定上下限報警值，接觸部件采用銀鎳合金材質(zhì)，確保在頻繁通斷工況下的接觸可靠性。指針軸系采用寶石軸承設(shè)計，配合精密游絲結(jié)構(gòu)，使儀器在機械振動環(huán)境下仍能保持測量精度。
產(chǎn)品適用于石油化工、電力設(shè)備、食品加工等行業(yè)的管道及反應(yīng)容器溫度監(jiān)控。直型軸向安裝結(jié)構(gòu)適配DN20及以上法蘭接口，產(chǎn)品整體尺寸經(jīng)過優(yōu)化設(shè)計，便于在有限空間內(nèi)完成安裝調(diào)試。用戶可根據(jù)需求選擇徑向或軸向表頭朝向，溫度刻度支持攝氏度與華氏度雙制式標注。
產(chǎn)品英文介紹：
The WZPK2-205SA Bimetal Thermometer with Electrical Contact is an industrial-grade temperature monitoring solution combining mechanical indication and electrical control functions. Its operation principle relies on the differential expansion characteristics of bonded metallic strips, providing reliable temperature measurement without requiring external power supply.
Crafted with 304 stainless steel casing, the instrument features a sandblasted finish for enhanced corrosion resistance. The 100mm diameter dial incorporates luminous markings and a red pointer for improved visibility in low-light environments. The hermetically sealed construction meets IP65 protection standards, safeguarding internal components from dust ingress and water splashes.
The bimetal sensing element delivers accurate readings across a -20℃ to 500℃ range (±1.5% full scale accuracy). Adjustable SPDT electrical contacts allow users to set customized alarm thresholds via front-mounted knobs. Silver-nickel alloy contacts ensure stable switching performance under continuous operation. The jeweled movement mechanism minimizes friction loss, maintaining long-term measurement stability even in high-vibration environments.
This thermometer excels in pipeline temperature monitoring for petrochemical plants, thermal power stations, and industrial boilers. Its straight axial mounting configuration fits standard process connections from DN20 upwards. The modular design allows field adjustment of pointer orientation while maintaining measurement integrity. Optional dual-scale dials (℃/℉) accommodate international engineering specifications.
