Pressure Transducer

The China pressure transducers usually composed of pressure sensitive elements and signal processing units. It is the most commonly used sensor in industrial practice and widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electricity, ships, machine tools , pipeline and many other industries.

The working principle of the diffused Ningdian® silicon pressure transducer  is also based on the piezoresistive effect. Using the piezoresistive effect principle, the pressure of the measured medium directly acts on the diaphragm (stainless steel or ceramics) of the Ningdian®  pressure transducer , so that the diaphragm produces a micro-displacement proportional to the medium pressure. 

The resistance value of the sensor is changed, the electronic circuit is used to detect the change, and a standard measurement signal corresponding to the pressure is converted and output.ND19 industrial pressure transducer adopt high performance chips, and deal with the special amplified chip, integrative configuration, and smart profile.
