Pneumatic and Hydraulic Pressure Sensors and its application.

  Pressure Sensor Technology:- Pneumatic and hydraulic sensors are transducers that generate an electrical signal in proportion to the measured pressure. This allows you to control the pressure with a variety of electronic devices. The most popular technology for pneumatic and hydraulic sensors uses a physical diaphragm made of silicon, which bends under pressure. The diaphragm is a tension meter, whose electrical resistance changes when the force is applied, in which case the electrical resistance varies due to the pressure exerted by the air, gas or hydraulic fluid of the sensor. This resistor is used to modify the sensor output voltage. Some pressure sensors for power steering applications use linear variable differential transformers. This includes a core that moves inside the hollow tube and monitors the movement of the high precision directional control valve, allowing hydraulic oil to flow to other areas of the system. Many pressure sensors are now independent, integrati
