How to choose a pipeline pressure sensor?

Pipeline pressure sensor is the most commonly used pressure sensor in industrial practice. It is widely used in various industrial self-control environments, involving oil pipelines, water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, Power, ships, machine tools, hydraulic machinery and many other industries.
The working principle of the pipeline pressure sensor is that the pressure of the medium acts directly on the diaphragm of the sensor, causing the diaphragm to generate a micro-displacement proportional to the pressure of the medium, causing the resistance of the sensor to change, and detecting the change by the electronic circuit and converting A standard signal corresponding to this pressure is output.
The pipeline pressure sensor is a meter that accepts a pressure variable and converts the pressure change amount into a standard output signal after being converted by the sensor. The output signal of the differential pressure transmitter is transmitted to the central control room for pressure indication, recording or control. When the pressure acts directly on the surface of the measuring diaphragm to cause a slight deformation of the diaphragm, the high-precision circuit on the measuring diaphragm transforms this tiny deformation into a highly linear voltage proportional to the pressure and proportional to the excitation voltage. The signal is then converted to an industry standard 4-2OmA current signal or a 1-5V voltage signal using a dedicated chip.
 
How to install a pressure sensor on a pipe?
Installation method:
Threaded pipe pressure sensor is usually equipped with a welding base, the base is welded on the pipe, the external thread of the sensor is screwed on the internal thread of the base; or the straight pipe is welded to the pipe to make the internal thread; Internal thread, specific analysis;
Flanged pipe pressure sensor, welding a flange on the pipe, docking installation.
