差圧伝送器。 A pressure-sensitive element that receives pressure on opposing surfaces and generates an electrical signal according to the pressure difference; a main body casing that forms a pressure chamber that encloses a medium that transmits the pressure to the pressure-sensitive element; In the pressure differential transmitter, the pressure differential pressure transmitter includes a diaphragm part attached to a casing and forming a part of the pressure chamber, and a pressure receiving flange sealed to the outer peripheral part of the diaphragm of the main body casing so as to surround the diaphragm part. A pressure differential pressure transmitter characterized in that a ring-shaped groove is provided in at least one of the parts where the outer circumference of the diaphragm and the pressure receiving flange are sealed, and a corrosion-resistant metal body is formed in this groove by melting and melting. .
