発信器。 A metal holder formed into an inverted bottomed cylindrical shape,
A long glass tube is suspended from the upper end of the metal holder with one end concentrically held, and a semiconductor pressure-sensitive sensor is fixed to the other end so as to close the opening. A cylindrical ceramic spacer is fitted into the metal holder so as to loosely surround the glass tube and has a lead pin insertion hole formed in the axial direction, and the ceramic spacer is inserted through the lead pin insertion hole. A lead pin is implanted in the upper end of the metal holder in this manner,
The differential pressure/pressure transmitter is characterized in that the ceramic spacer has at least an outer circumferential portion on the lower end side tightly fitted to the inner wall portion of the metal holder.
