SIEMENS防霜恒溫開關(guān)QAF81系列介紹
霜凍裝置 QAF81... 用于通風(fēng)和空調(diào)系統(tǒng)中 LTHW 加熱盤管溫度的空氣側(cè)監(jiān)控，用于防止霜凍損壞。 它具有開關(guān)差小、重復(fù)性好等特點(diǎn)。 復(fù)位自動(dòng)發(fā)生（QAF81.6M 需要手動(dòng)復(fù)位）。
? 堅(jiān)固的鋁壓鑄外殼
? 對(duì)任何 30 - 100 厘米長(zhǎng)度的毛細(xì)管上感測(cè)到的溫度變化做出響應(yīng)
? 切換差異小
? 良好的重復(fù)性
? 設(shè)定值調(diào)整 (-5...+15 °C)
? 防護(hù)標(biāo)準(zhǔn)IP54 (65)
The frost unit QAF81... for air-side monitoring of the temperature of LTHW heating coils in ventilation and air conditioning systems is used to prevent frost damage. It has a small switching differential and good repeatability. The reset occurs automatically (manual reset required with QAF81.6M).
? Robust aluminium die-cast housing
? Responds to temperature change sensed over any 30 - 100 cm length of capillary
? Small switching differential
? Good repeatability
? Setpoint adjustment (-5...+15 °C)
? Protection standard IP54 (65)
