Pressure Transmitter |
| 摘要 |
A pressure transmitter including tube-like pressure introducing pipes, a sealed-in liquid, the inside of the pressure introducing pipes being filled with the sealed-in liquid, pressure receiving diaphragms for receiving the pressures of measurement fluids, the pressure receiving diaphragms being set up in a state where one-side apertures in the pressure introducing pipes are blocked by the pressure receiving diaphragms, a pressure sensor that is set up in common to the other-side apertures in the pressure introducing pipes in a state where the pressure sensor is exposed to the sealed-in liquid, and hydrogen-permeation prevention layers that are set up on the pressure receiving diaphragms, wherein the pressure transmitter further includes a hydrogen-storage material that is set up inside the pressure introducing pipes. |

1. A pressure transmitter, comprising:
tube-like pressure introducing pipes; a sealed-in liquid, the inside of said pressure introducing pipes being filled with said sealed-in liquid; pressure receiving diaphragms for receiving the pressures of measurement fluids, said pressure receiving diaphragms being set up in a state where one-side apertures in said pressure introducing pipes are blocked by said pressure receiving diaphragms; a pressure sensor that is set up at the other-side apertures in said pressure introducing pipes in a state where said pressure sensor is exposed to said sealed-in liquid; and hydrogen-permeation prevention layers that are set up on said pressure receiving diaphragms, wherein said pressure transmitter further comprises a hydrogen-storage material that is set up inside said pressure introducing pipes. |
