Pressure Sensors, Transducers, and the PPT2-0005DXR5VE Application Field and Working Principle

The PPT2-0005DXR5VE is a common type of pressure sensor,transducer, pressure transducer, or pressure transmitter. It is an electrical device used for sensing pressure in applications such as automotive applications, heating and cooling systems, gas pressure measurement, refrigeration systems, hydraulics, and in many industrial processes.

The PPT2-0005DXR5VE can measure pressure ranging from (0.5 bar) to 2.0005 bar (20001062 Pa) with a high accuracy of 3.1% of the full scale range. Pressure is measured via a Wheatstone bridge circuit consisting of a strain gauge consisting of a resistor, a capacitor, a piezo resistor, and an inductor. The bridge is built into the sensor\'s body and is typically filled with silicone oil.

A major function of the transducer is to convert pressure into an electrical signal. This is achieved through a conversion process which is typically referred to as a ‘bridge’. Inside the bridge is the strain gauge which is made up of four components: a resistor, a capacitor, an inductor, and a piezoresistor. This bridge provides the necessary output voltage, which is proportional to the pressure applied to the strain gauge.

In operation, when pressure is applied to the strain gauge, the piezo resistor and capacitor respond differently. The piezo resistor increases its resistance as the pressure is increased, while the capacitor changes the capacitance in response to pressure. This interaction generates an electrical signal, which is then output as a voltage.

The PPT2-0005DXR5VE is an ideal solution for a variety of applications due to its wide range of pressure measurement, its high accuracy, and its robustness. It is commonly used in measuring pressures in hydraulic and pneumatic systems, fuel and oil systems, and in applications such as weather forecasting and environmental monitoring. This pressure transducer is also used in automotive engineering, HVAC systems, and in medical equipment.

Overall, the PPT2-0005DXR5VE pressure transducer is an excellent choice for a wide range of applications. Its wide range of pressure measurement, its high accuracy, and its robustness make it ideal for many industries and applications.
