Pressure Sensors and Transducers: P51-500-S-A-I12-20MA-000-000

Pressure sensors and transducers are essential components for many industries, providing accurate and reliable pressure measurements. The P51-500-S-A-I12-20MA-000-000 is an example of one such sensor, designed specifically for industrial applications. In this article, we\'ll take a look at its application field and working principle.

Application Field

The P51-500-S-A-I12-20MA-000-000 is suitable for a wide range of applications in the industrial sector. Its stainless-steel construction makes it highly suitable for applications involving chemicals, corrosion and temperatures up to 250 °F (121 °C). The low-cost package offers a very low power consumption and long-term stability.

Furthermore, the P51-500-S-A-I12-20MA-000-000 has excellent pressure accuracy at a measurement range of 0 to 500 PSI and a 3-digit resolution. It has an adjustable zero point, providing additional flexibility. The P51-500-S-A-I12-20MA-000-000 is designed to operate in industrial systems such as pumps, compressors, and other pressurized systems. Additionally, it is capable of measuring absolute and gauge pressures.

Working Principle

The P51-500-S-A-I12-20MA-000-000 is a piezoresistive pressure sensor, meaning that it is based on the piezoresistive effect. This effect occurs due to the electrical resistance of a material to change when a mechanical stress or strain is applied. In this case, the material is a semiconducting silicon element, which forms a Wheatstone bridge circuit when a pressure is applied onto it.

The Wheatstone bridge is a circuit consisting of four resistors and a voltage source. The resistors are arranged in a circuit in such a way that one of the resistances changes when a pressure is applied to the semiconductor element. This resistance can then be measured as an output voltage that is proportional to the applied pressure. Thus, the output voltage can be used to measure the pressure in the system.

The P51-500-S-A-I12-20MA-000-000 has a maximum operating pressure of 500 PSI and a minimum operating pressure of 3 PSI. Additionally, it has a zero boot range of -5 to 500 PSI. It has a nominal output current of 12 to 20 mA and can be wired in two-wire or three-wire connection. This allows for easy integration with industrial systems.

Conclusion

The P51-500-S-A-I12-20MA-000-000 is a reliable and low-cost pressure sensor designed for industrial applications. Its stainless-steel construction and low-cost design make it suitable for a wide range of industrial applications. The sensor is based on the piezoresistive effect, allowing for a proportional output voltage that is directly related to the applied pressure. With its adjustable zero boot range and two-wire and three-wire connection options, the P51-500-S-A-I12-20MA-000-000 is an ideal choice for many industrial pressure measurement applications.
