Claims (1)
ーを、液体流路とは隔膜によつて分離された圧力
感知室と、該圧力感知室に連通連結されていて、
液体流路の圧力変化に伴う圧力感知室の容量変動
に応じて封入液の液面が変位する液柱管と、該液
柱管での液面変位を検知するセンサー部とで構成
すると共に、前記液柱管は、液体流路と略平行で
、しかも液体流路の下方に配したことを特徴とす
る液体の圧力検知センサー構造。 A liquid pressure detection sensor provided in the liquid flow path is connected in communication with a pressure sensing chamber separated from the liquid flow path by a diaphragm,
Consisting of a liquid column tube whose liquid level of the sealed liquid is displaced in response to a change in the capacity of a pressure sensing chamber due to a pressure change in a liquid flow path, and a sensor section which detects the liquid level displacement in the liquid column tube, The liquid pressure detection sensor structure is characterized in that the liquid column tube is arranged substantially parallel to the liquid flow path and further below the liquid flow path.
