RPMC系列穩(wěn)定臨界室內(nèi)壓力監(jiān)測器適用于要求嚴(yán)格的壓力監(jiān)測和報警的臨界低壓差應(yīng)用場合。該系列RPMC可配置用于監(jiān)控保護(hù)環(huán)境和清潔制造區(qū)域的正或負(fù)壓力。RPMC是一個完整的系統(tǒng)，它可以實現(xiàn)壓力、安全、校準(zhǔn)和報警設(shè)置。具有拉絲不銹鋼邊框，便于清洗。
內(nèi)置狀態(tài)指示led，在用戶定義的壓力設(shè)置范圍內(nèi)顯示為綠色，在壓力設(shè)置范圍外顯示為橙色。2 SPDT獨立控制繼電器可調(diào)死區(qū)也提供了一個4-20毫安的過程輸出。
