RHP-W系列墻裝式溫度/濕度/露點(diǎn)變送器是一款多用型的室內(nèi)用變送器。 外殼上美觀排列的通風(fēng)孔可以改善空氣流經(jīng)傳感器而提高測量精度??蛇x 嵌入式LCD顯示,也可選擇遠(yuǎn)傳式LCD顯示,這些功能能夠幫助取得綠色 建筑LEED證書。LED同時(shí)顯示溫度和濕度或露點(diǎn)。變送器內(nèi)帶的撥動(dòng)開 關(guān)可選擇溫度單位,輸出為濕度或露點(diǎn)??涩F(xiàn)場替換的溫濕度傳感器能夠
幫助節(jié)約維護(hù)維修成本,減少倉儲(chǔ)量。采用電容高分子聚合物濕度傳感 器,它能夠在經(jīng)過99%的高濕后恢復(fù)測量特性。濕度和露點(diǎn)輸出可選擇 電流或電壓輸出,溫度可任意選擇電流,電壓,熱電阻或熱敏電阻。當(dāng)溫
度輸出為電流或電壓輸出時(shí),溫度量程是可以現(xiàn)場選擇的。
可選/&'顯示,可顯示輸出露點(diǎn),傳感器可現(xiàn)場替換
