P51-2000-S-N-D-20MA

Pressure Sensors and Transducers

P51-2000-S-N-D-20MA is a product of pressure sensors and transducers. Regardless of the application field, the working principle of a pressure sensor is the same. It senses physical pressure such as gas, liquid, steam or air pressure, and then converts it into an electrical signal that can be detected by the instrument or computer. Pressure sensors and transducers are useful tools used in a flux of industries such as process automation, transportation, HVAC, water and wastewater, and instrument engineering.

Application Field

In the broadest sense, pressure sensors and transducers can be used in all applications that require pressure monitoring or control. Common applications include process control, power plants, pressure switches, leak testing, and medical diagnostics. They can also be used to measure and regulate the pressure of liquid and gas flow, as well as monitoring temperatures, building automation, and safety systems.

P51-2000-S-N-D-20MA is an industrial-grade pressure sensor, which is most commonly used in instrument and process control. It is designed and manufactured for high performance in harsh industrial environments. Its robust construction and high accuracy make it ideal for pressure monitoring and control applications that require reliable performance and repeatability in extreme conditions.

Working Principle

The working principle of a pressure sensor is basically the same regardless of the application field. It consists of two pressure-sensitive elements, each one connected to a diaphragm. The diaphragm absorbs the physical pressure and converts it into a deflection. This deflection is then detected by the first element, which sends an electrical signal to the second element. The second element further amplifies the signal, and converts it into an output voltage signal that is readable by the instrument or computer.

P51-2000-S-N-D-20MA pressure sensor is based on the Wheatstone bridge principle, which has four resistances arranged in a triangular shape. The bridge is powered with an excitation voltage and the output is a voltage with information on the measured pressure. The output voltage is transmitted to the receiving device where it is processed and measured. The Wheatstone bridge principle is sensitive to small changes in pressure, making it ideal for precision measurement and control applications.
