Claims (1)

[Claims for Utility Model Registration] (1) A connection between a main body portion which is closed by a pressure receiving diaphragm and has a pressure transmitting medium and a pressure sensitive element inside the main body portion, and an outer surface of the pressure receiving diaphragm which is airtightly attached to the main body portion. and a pressure introducing flange that introduces fluid pressure into the recessed part of the flange, the introduced fluid pressure is received by the pressure receiving diaphragm, and the pressure transmitted via the pressure transmission medium is converted into an electrical signal by the pressure sensitive element. 1. A pressure transmitter for transmitting data through a pressure transmitter, characterized in that the pressure introducing flange has a restricting means connected in series to a piping connection port thereof. (2) The throttling means is a capillary tube whose one end is connected to the piping connection port inside the pressure introduction flange, the required length is housed inside the pressure introduction flange, and the other end is opened inside the flange. A pressure transmitter according to claim 1, characterized in that the pressure transmitter is formed as follows. (3) The throttling means has a narrow groove carved in an appropriate pattern on the bottom surface of the recess in the flange of the pressure introduction flange, one end of which is connected to the communication hole that communicates with the piping connection port, and extends for the required length. , a plate-like body fitted into the flange-internal recess is engraved corresponding to at least a part of the pattern on a surface that abuts with the bottom surface of the flange-internal recess, and an end portion far from the communication hole is formed on the plate-like body; 2. The pressure transmitter according to claim 1, wherein the pressure transmitter is formed of a thin groove connected to a through hole passing through the pressure transmitter. (4) The throttling means is attached to the outer surface of the pressure introduction flange where the piping connection port is provided through packing concentrically with the piping connection port, and the piping connection screw is installed on the surface opposite to the contact surface. The adapter is characterized in that the adapter has a hole concentrically with the piping connection port and a throttle hole that communicates the bottom surface of the piping connection threaded hole with the abutment surface and is provided concentrically with the piping connection threaded hole. A pressure transmitter according to claim 1 of the utility model registration claim.
