Pressure sensors and transducers are used within the field of industrial automation and control systems, and provide the means to detect dynamic pressure operating in certain conditions. The PPT0500DXX5VA is one such sensor, and is designed to measure medium to high pressure levels. This article looks in detail at the PPT0500DXX5VA application field and working principle.

The main applications of the PPT0500DXX5VA include regulating airflow within a fluid, measuring static pressure in a fuel system, monitoring a vehicle’s fuel tank or measuring pressure levels in a hydraulic system. The PPT0500DXX5VA can measure pressure levels of up to 20 bar (200 kPa).

Based on the piezoelectric technology, the PPT0500DXX5VA is a piezoresistive transducer that utilizes a piezoresistive silicon membrane as its active sensing component. This membrane is supported by a stainless steel housing and the sensing membrane is tightly wound with an electrical coil. A thin film of metal is sandwiched between the membrane and coil, and it acts as a variable resistor when the pressure on the membrane changes.

The working principle of the PPT0500DXX5VA is relatively straightforward. Whenever a pressure is applied to the membrane, a force is generated along the lead lines connected to the active sensing electrode, which causes the resistance value of the film to change. This in turn causes an output voltage signal from the transducer that is proportional to the pressure applied. This output voltage signal can then be read and interpreted by an appropriate controller or measurement instrument.

The PPT0500DXX5VA is designed to provide an accurate and reliable measurement of pressure levels, and provides a low power consumption and an excellent linearity/accuracy of ±0.byxx5 %FS. It is also designed to be robust and reliable, with a wide operating temperature range of -40 °C to +105 °C, and ZVT(Zero Void Technology) for long-term stability against temperature changes, vibration and shock.

Furthermore, the PPT0500DXX5VA is suitable for both industrial and automotive applications, with a wide voltage range of 5-35V DC and an operating current of 5 mA (max). It has a wide dynamic range of 0.5-20 bar (5-200 kPa), and an increased isolation of up to 1,500 VDC.

The PPT0500DXX5VA can be used in both analogue and digital applications and is RoHS compliant. It is a robust and reliable pressure sensor, which has been designed to provide accurate and reliable pressure readings over a range of medium to high pressure levels.
