AVPT系列筆形風(fēng)速變送器采用熱風(fēng)速計(jì)技術(shù)，以英制和公制單位提供高精度和穩(wěn)定的風(fēng)速測(cè)量。 該系列AVPT可配置電壓輸出或BACnet MS/TP通信，為各種監(jiān)測(cè)設(shè)備提供通用輸入。 型號(hào)可提供固定電纜長(zhǎng)度為20或78英寸的飛行導(dǎo)線或5針M12連接器的24英寸電纜。 探頭長(zhǎng)度可達(dá)6英寸或12英寸。 該產(chǎn)品包括一個(gè)安裝法蘭，能夠改變插入深度。
精度可達(dá)3%或5%，以適應(yīng)各種應(yīng)用程序，而可選的BACnet MS/TP通信協(xié)議允許對(duì)單元進(jìn)行連接，以提供對(duì)所有速度和溫度測(cè)量
傳感元件已涂上了工程保形涂層，以確保耐久性和壽命
不同探頭長(zhǎng)度 便于安裝
