Claims

[Scope of utility model registration request]

The inside of the case is partitioned by a pressure-receiving member equipped with an elastic membrane to form two pressure-receiving chambers within the case, and a core attached to the pressure-receiving member is inserted into the hollow part of the detection coil supported by the case. In a pressure gauge that is movably inserted in the axial direction of the coil and outputs a pressure detection signal from the detection coil that is proportional to the amount of movement of the core, one pressure receiving chamber has two plates along the radial direction of the detection coil. disposing leaf springs and fixing the proximal ends of these leaf springs to the case;
The core was fixed to the tip, and the bobbin wound with the detection coil was airtightly attached to a mounting hole in the outer wall of the case, and the bobbin was detachably attached to the outer wall of the case using a fastening member. A pressure gauge characterized by:
