俄羅斯comeco 溫濕度傳感器 - RH/T-e
產品介紹
一、俄羅斯comeco 溫濕度傳感器 RH/T-e描述:
利用電容隨介質相對濕度成比例變化的薄膜傳感器，RHT測量空氣和非腐蝕性氣體的RH，并將其轉換為標準的4-20mA 2線信號。內置溫度漂移補償系統(tǒng)，保證了測量的良好穩(wěn)定性，并可內置額外的溫度傳感器或第二線發(fā)射機，用于測量介質相對濕度和溫度。RH變送器出廠校準，無需自定義調整，溫度變送器可現場額外校準。該設備有三種不同的安裝和溫度范圍的變體。所有這些，加上高保護等級、小尺寸和低價格，使RHT成為許多RH測量應用的一個方便的解決方案。
二、俄羅斯comeco 溫濕度傳感器 RH/T-e特點：
2線RH/T發(fā)射機RHT
低成本溫度補償系統(tǒng)
兩個用于RH和溫度的2線變送器
可選內置Pt溫度傳感器
可選配不銹鋼燒結過濾器
IP65保護
