Pressure Sensors, Transducers

Pressure sensors and transducers are essential components in many industrial processes, from laboratory research to factory automation. These components allow engineers and scientists to measure, observe, and analyze physical phenomena as well as control processes. There are a variety of pressure sensors and transducers available on the market, such as the RDP-61-500-A-A-I24-20MA-A.

Application Field

The RDP-61-500-A-A-I24-20MA-A pressure sensor is designed for use in air pressure measurement applications. It is specifically designed for measuring relative pressure, which is the difference in pressure measured in two places. The sensor is able to measure both positive and negative relative pressures, ranging from -500kpa (-50bar) to 500kpa (50bar). The pressure range is adjustable, allowing the user to change the value depending on the required measurement. This sensor also features an accuracy of ±0.5% FS, offering reliable readings in a wide range of applications.

Working Principle

The RDP-61-500-A-A-I24-20MA-A pressure transducer works on the principle of a strain gauge. A strain gauge is a sensor that measures very small changes in physical dimensions, such as force or pressure. When connected to a bridge circuit such as a Wheatstone bridge, the strain gauge can measure changes in an electrical signal in response to a mechanical force applied to it. In the case of the RDP-61-500-A-A-I24-20MA-A, a thin foil strain gauge is used to detect changes in the pressure applied to the diaphragm. The diaphragm is the key component of the sensor, and it is positioned in the center of the threaded housing.

The Wheatstone bridge circuit is completed by connecting the strain gauge to four resistors. When the pressure changes, the strain gauge changes its value, impacting the bridge circuit and generating a corresponding output voltage. This output voltage is then processed by the circuits embedded in the sensor, providing a direct reading. The RDP-61-500-A-A-I24-20MA-A pressure transducer provides a 4-20mA signal for easy interfacing with other systems.

Conclusion

The RDP-61-500-A-A-I24-20MA-A pressure transducer is a reliable pressure measurement device for industrial and laboratory applications. It employs rugged construction and a strain gauge-based design, allowing it to accurately measure relative pressures ranging from -500kpa to 500kpa. The device also has a fairly low power dissipation, making it ideal for applications that require a low-power solution. Beyond that, the integrated Wheatstone bridge circuit and 4-20mA signal output provide an easy way to integrate the sensor in other systems.
