Application of flush diaphragm pressure sensor 

      The working principle of the flush diaphragm pressure sensor is based on the effect of medium pressure on the sensor diaphragm. When the measured medium (gas or liquid) exerts pressure on the diaphragm of the sensor, the diaphragm will produce a micro displacement proportional to the pressure of the medium. This micro-displacement causes a change in the resistance of the sensor, which in turn produces an electrical signal corresponding to the pressure. After the electrical signal is detected and converted by the electronic circuit, the final output is a standard signal corresponding to the measured pressure. 

       In the wave of industrial automation and intelligent manufacturing, pressure sensors, as a core component, provide key support for the safety, efficiency and precision of the production process. GRAEFF flush diaphragm pressure sensors are widely used in the chemical and petroleum industries, the automotive industry, medical equipment, meteorological and environmental monitoring, aerospace and other fields.
