Pressure Sensors, Transducers

Pressure sensors and transducers are invaluable tools in a variety of applications, ranging from automotive and aviation to industrial process control and environmental monitoring. The PG-30-102R-N is a typical example of a pressure sensor used in many of these applications for measuring, monitoring, and controlling pressure. In this article, we will discuss the PG-30-102R-N’s application fields and working principle.

Application Fields

The PG-30-102R-N is ideal for a variety of industrial pressure measurement applications. It is most commonly used for measuring air and gas pressure, including refrigeration pressure,differential pressure, and absolute pressure. It is also useful for measuring liquid pressures, such as for fuel injection pressure control, water levels, and flow rates. It can also be used to measure vacuum. Its wide range of applications makes it a necessary tool for many industrial and commercial establishments.

Working Principle

The PG-30-102R-N is a piezoresistive pressure sensor, meaning that it works on the principle that the resistance of the material it is made of changes when pressure is applied. It is made of a thin film strain gauge made of metal foil, which is attached to a silicon diaphragm. When pressure is applied to the diaphragm, the strain gauge’s resistance changes. This resistance is then converted into a suitable voltage output which can be read by a suitable instrument or used in a control system.

The PG-30-102R-N is highly accurate and comes with several features that make it a top choice for many applications. The pressure range of the sensor is 0-120 psi, with an accuracy of 0.25%. The sensor is designed to maintain its accuracy even under extreme temperatures, ranging from -40 to 125 degrees Celsius. The sensor is also designed to be highly resistant to interference from electrical and electromagnetic fields. This makes it suitable for use in areas with high levels of electromagnetic radiation.

The PG-30-102R-N is a reliable and dependable pressure sensor for a variety of applications in different industries. Its accuracy and features make it a popular choice for many industrial and commercial establishments. With its wide range of applications, it is an invaluable tool for measuring, monitoring, and controlling pressure.
