体クロマトグラフ用圧力センサ。 A pressure sensor is installed between a liquid feeding pump and an injector in the piping system of a liquid chromatograph and detects the pressure within the piping system. The main channel communicates with the injector line connection port at the other end through the hydraulic pressure chamber in which a line filter can be set, and the needle valve provided therein allows for opening and closing. A pressure sensor for a liquid chromatograph, characterized in that a tube can be connected thereto and a drain flow path communicating with the liquid pressure chamber is provided.
