摘要： PROBLEM TO BE SOLVED: To solve the problem that hydrogen having invaded into a pressure and differential pressure transmitter from outside or internally generated hydrogen and hydrocarbons turn into foams in a pressure guiding path to invite drifting of indicated values and failure to output accurate values.SOLUTION: In a pressure and differential pressure transmitter in which a pressure guiding path encloses sealing liquid for transmitting pressure, a space is to be formed between a diaphragm and a body side wall face. The pressure guiding path is connected to the body side wall face, and a pressure received by the diaphragm is transmitted to a sensor via the sealing liquid enclosed in the space and the pressure guiding path. The configuration is such that a hydrogen adsorbing material for adsorbing hydrogen atoms in the sealing liquid is disposed at least in the sealing fluid, the body side wall face or part of the area extending from the body side wall face to the sensor.

The first and second differential images are input into an analyzer 207. The refractive index of the water, in the route of the reflected light 102b, is further uniformized by the stream 107a, so that the existence of cracks can be detected accurately by underwater nondestructive inspection that uses the laser beam.
