Pressure transmitter with integrated encapsulation type sensor

The invention relates to a site pressure measuring instrument and aims to provide a pressure transmitter with an integrated encapsulation type sensor. The pressure transmitter comprises an integrated encapsulation type sensor which comprises a flange with a hollow flange surface, wherein the middle part at the front side of the flange surface is provided with an annular pillar-shaped interface port protruding out of the flange surface; the rear side of the flange is provided with a hollow flange body, a sensor is arranged at the front end in the flange body, and a lead-out signal wire of the sensor is connected to a signal processing unit; a main circuit connecting lead is led out from the rear end of the signal processing unit and connected to a modularized main circuit board; and epoxy resin used for encapsulating is used for sealing and fixing the signal processing unit at the rear end in the flange body. The invention has the advantages of small volume and more convenient mounting, reduces site mounting a
