力センサー。[Claims for Utility Model Registration] A pressure chamber consisting of an outer wall of a bellows and a pressure vessel covering the outer wall of the bellows is provided at one end of the piping filled with a substance to be measured, and a bias spring is provided inside the bellows. A shaft penetrating the bias spring is attached, and the bellows expands and contracts in response to an increase or decrease in the pressure in the pressure chamber, and in combination with the bias spring, the shaft is moved linearly in response to the pressure in the pressure chamber. On the other hand, a magnetic core is provided at the tip of the shaft, a coil constituted by a wound bobbin is attached to the pressure vessel adjacent to the magnetic core, and the coil and the magnetic core are connected to each other. Due to relative movement,
A pressure sensor comprising a differential transformer to continuously convert the pressure within the pressure chamber into an electrical signal.
