Pressure transmitter

Technical Field

The utility model relates to an electronic equipment field relates to a pressure transmitter particularly.

Background

A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. The pressure transmitter can convert physical pressure parameters of gas, liquid and the like sensed by the load cell sensor into standard electric signals to be supplied to secondary instruments such as an indication alarm instrument, a recorder, a regulator and the like for measurement, indication and process regulation. The connection of the existing pressure transmitter and the pipeline to be measured is designed more traditionally, and the pressure resistance is poor due to simple threaded connection when the pressure transmitter is tightly connected, so that the connection is poor in sealing performance and easy to crack or leak, and pressure measurement is not accurate enough.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a pressure transmitter, can effectively improve pressure transmitter and the compressive resistance and the leakproofness of the junction of being surveyed the pipeline, prevents junction fracture or gas leakage, guarantee pressure measurement's precision.

In order to achieve the above object, the present invention provides the following technical solutions:

this pressure transmitter is including the changer body that is equipped with signal input line and power supply and signal output line, and changer body intercommunication has the survey buret, surveys buret intercommunication and has the two tubular clamp pipes of semicircle, and two clamp pipe both sides all are equipped with flat splint, and two pairs of splint run through have a plurality of bolts, and every bolt all is furnished with mutual screw-thread fit's nut, and two intraductal clamp holds the support intubate of semicircle.

As a further optimization of the technical scheme, the shell and the measuring pipe of the transmitter body are both made of stainless steel, and the shell and the measuring pipe of the transmitter body are of an integral structure.

As a further optimization of the technical scheme, the clamping pipe and the clamping plate are both made of stainless steel, and the clamping pipe and the clamping plate which are connected with each other are both of an integral structure.

As a further optimization of the technical scheme, the bolt and the nut are both made of stainless steel.

As a further optimization of the technical scheme, the supporting insertion tube is made of stainless steel, and the outer diameter of the supporting insertion tube is smaller than the inner diameter of the clamping tube.

The beneficial effect of adopting above technical scheme is: when the pressure transmitter is used, the support insertion pipe can be inserted into two sections of pipelines to be measured, then the two clamping pipes are clamped on the two pipelines to be measured, the clamping plates penetrate through the bolts, the nuts are screwed, and the two pipelines to be measured and the measuring pipe are fixedly connected through the clamping pipes. The transmitter body measures the pressure of gas or liquid in a measured pipeline and sends the pressure to the measuring terminal through a power supply and signal output line. This pressure transmitter can effectively improve pressure transmitter and the compressive resistance and the leakproofness of the junction of being surveyed the pipeline, prevents that junction fracture or gas leakage, ensures pressure measurement's precision.
