とする圧力センサー。 A pressure chamber is provided at one end of the piping filled with the gas to be measured, a bellows is placed inside the pressure chamber, and the displacement of the bellows due to pressure changes is measured via a shaft using a so-called differential transformer consisting of a magnetic core and a coil. In particular, in a pressure sensor that detects pressure by forming a male thread (or female thread) at the tip of the shaft, and a female thread (
or a male thread) is formed at the end of the magnetic core,
A pressure sensor characterized in that the position of the magnetic core relative to the shaft can be slightly moved by rotation of the magnetic core.
