ンサ。 Piping is installed on one side of a frame-shaped frame, and a bellows is installed that causes displacement according to the pressure of the substance to be measured, and a magnetic core is installed at the tip of the bellows. In a pressure sensor, a coil is attached to the holder to form an actuating transformer in combination with the magnetic core, and the displacement of the bellows is continuously converted into an electric signal by the actuating transformer. A pressure sensor characterized in that a holder contact portion is provided in the portion to come into contact with the protrusion.
