Beschreibung
Zusammenfassung:	Provided is a pressure transmitter. A cavity is disposed on an upper part of a base. A bottom end of the base is provided with a blind hole. The bottom surface of the blind hole and the bottom surface of the cavity form a strain wall. An amplifier circuit board and a strain gauge connected with the amplifier circuit board are disposed in the base. The strain gauge is attached on the strain wall. A cable connected with an output end of the amplifier circuit board extends out of the base. An end cap is embedded in the blind hole, and an upper end face of the end cap is provided with a groove connecting through an edge of the end cap. A lower part of the base is provided with two holes. Two ports of the groove on the end cap are respectively abutted with the holes. The groove is abutted with the two holes, and a fluid passageway is formed in the base. When the fluid pressure transmitter is used, the two holes on the base are connected with a pipe tested fluid flows through. When the tested fluid flows through th
