Introduction

Pressure sensors, or pressure transducers, are devices used to measure and transmit pressure in various application fields. In this article, we will focus on the PPT0020ARN5VB, a pressure transducer made by the German company Electronic Measurement GmbH (EMG).

Application Field

The PPT0020ARN5VB pressure transducer offers excellent precision and accuracy in static pressure application fields. It features an LCD display for reading measured values, and is perfect for pressures up to 30 MPa (300 bar). The transducer is also suitable for vacuum measurements down to -1 mbar. It is especially suitable for applications in the hydraulics or pneumatic fields, water pressure measurement, chemistry processes, sintering, and research laboratories.

Working Principle

The PPT0020ARN5VB pressure transducer operates by sensing and measuring the electrical resistance (or strain) of a special diaphragm made of ceramic or solid metal. When the pressure being measured is applied to the diaphragm, it deforms and changes its electrical resistance. This change in electrical resistance is measured and converted into a voltage signal that is then outputted as an indication of the pressure being measured. The output voltage is proportional to the pressure being measured and is calculated by the following formula:

Output Voltage = Pressure x Sensitivity

The PPT0020ARN5VB is a high-precision device with an excellent linearity, requiring only minimal maintenance. It features a wide dynamic range and is capable of measuring both positive and negative (vacuum) pressures. The transducer also features a high-level of electrical noise rejection, which ensures consistently accurate results, even in applications with varying temperature.

Conclusion

In conclusion, the PPT0020ARN5VB pressure transducer is a highly accurate and reliable device suitable for a wide range of static pressure measurements. With its excellent linearity, wide dynamic range, and high-level of electrical noise rejection, it can be used in a variety of application fields, including hydraulics, pneumatics, water pressure measurement, chemistry processes, sintering, and research laboratories.
