Pressure sensors, transducers, and transmitters are all important devices used in the field of fluid flow and pressure. The particular device discussed here is the PS20-302R-NM, which is used to measure and monitor the pressure of liquids and gases in a variety of different environments and processes. In this article, we will discuss the application field and working principle of the PS20-302R-NM.

The PS20-302R-NM is a precision pressure transducer which is capable of monitoring and measuring the pressure of liquid and gaseous media in a variety of environments and processes. It is designed to provide a stable and reliable measurement of pressure over a wide range of temperatures and pressure range levels. The PS20-302R-NM is ideal for use in a variety of applications, including but not limited to industrial process control, process monitoring, research and development, chemical and petrochemical processes, environmental testing, and hazardous area applications.

The PS20-302R-NM is constructed of an all-welded stainless steel pressure vessel which houses a piezoresistive sensor element. This element is capable of providing a precise and accurate measurement of pressure in both liquid and gaseous media. The sensor element is regulated and temperature compensated using a built-in temperature sensor, which helps to ensure that the output is reliable and accurate at all temperatures.

The operating principle of the PS20-302R-NM is based on the Wheatstone bridge principle. The sensor element is located inside the pressure vessel and consists of a small ceramic diaphragm and four strain gauges. When pressure is applied to the diaphragm, it bends slightly and causes a change in the electrical resistance of the strain gauges. This change in resistance creates an electrical signal which is proportional to the pressure being measured.

This electrical signal is sent to a processing unit which converts it into a linear output signal and transmits it to a display device, such as a computer monitor or a data logger. The output signal is then used to create a graph or chart of the pressure being measured.

The PS20-302R-NM is a highly accurate and reliable pressure transducer which offers a wide range of features and capabilities. It is ideal for many applications in a variety of industries, from industrial process control and monitoring, to research and development, to environmental testing and hazardous area applications. The device is especially suited to applications which require a high degree of accuracy and stability, as it is temperature compensated and regulated to ensure reliable results. Moreover, it is capable of providing a high degree of accuracy even in high temperatures and pressures. In conclusion, the PS20-302R-NM is a versatile and reliable pressure sensor which can meet the needs of a variety of professionals and industries.
