壓力開關(guān)采用高精度、高穩(wěn)定性能的壓力傳感器和變送電路,再經(jīng)專用 CPU模塊化信號處理技術(shù),實現(xiàn)對介質(zhì)壓力信號的檢測、顯示、報警和控制信號輸出。壓力開關(guān)可以廣泛用于石油、化工、冶金、電力、供水等領(lǐng)域中對各種氣體、液體的表壓、絕壓的測量控制,是工業(yè)現(xiàn)場理想的智能化測控儀表。
DPA model is ideal for the application (such as HVAC) with differential pressure, vacuum pressure, gauge pressure and especially low pressure of non-corrosive gases or air measured. Device for Ultra Low Pressure Gauge / Switch, which is using MICOM, improved Accuracy and Temperature compensation.
韓國Sensys DPA是一款差壓、真空壓力、表壓力和特別是低壓無腐蝕性氣體測量應(yīng)用(例如HVAC應(yīng)用)而設(shè)計的壓力傳感器。作為一款超低壓壓力計/壓力開關(guān),DPA內(nèi)置MICOM,可提高其精度和溫度補償。
