Abstract
A diaphragm seal includes a first diaphragm that faces a measurement medium, a sealed-liquid housing, and a second diaphragm. The first diaphragm receives pressure from the measurement medium. The sealed-liquid housing houses a sealed liquid for transferring the pressure to a transmitter. The second diaphragm causes hydrogen intruded into the sealed liquid to permeate through the second diaphragm and be discharged from the sealed liquid.
