Pressure Sensors and Transducers are device components used to convert one type of physical quantity into an electrical signal. The P51-75-S-H-MD-20MA-000-000 is one such device, a transducer which measures and records pressure data. This article will discuss the application field and working principle of this pressure transducer.

Application Field

The P51-75-S-H-MD-20MA-000-000 pressure transducer is designed for rugged industrial applications where precision and accuracy are required. It is a general-purpose pressure transducer with excellent shock and vibration resistance, making it ideal for applications including chemical processing, petrochemical processing, power generation, and water supply. In addition, the device is rated for operating temperatures ranging from -20°C to +85°C, and has a dielectric strength of 1000V.

Working Principle

The P51-75-S-H-MD-20MA-000-000 pressure transducer utilizes a piezoresistive strain gauge technology in order to measure pressure. A strain gauge is a type of electromechanical device that uses a physical strain to measure the pressure applied to it. The principle of operation involves a resistance element that changes its electrical resistance when subjected to a physical strain. The piezoresistive strain gauge used in this device is composed of a metal resistor that changes its electrical resistance when subjected to a mechanical stress. This change in electrical resistance is then converted to an electrical voltage, which is then used to measure and record the pressure applied to the device.

The transducer is equipped with a range of features that are designed to improve accuracy and reliability. These include low hysteresis, wide temperature range and dynamic range, high overpressure capability, mechanical and electrical overload protection, and spike protection. The device also meets industry standards for accuracy and repeatability, with a maximum zero shift of 0.03% of full scale.

In addition, the P51-75-S-H-MD-20MA-000-000 pressure transducer utilizes a Wheatstone bridge configuration. The Wheatstone bridge is a circuit that consists of four resistors arranged in a symmetrical configuration, such that when a voltage is applied across two of the resistors, the voltage measured at the other two points is proportional to the applied pressure. This voltage can then be used to determine the pressure being applied to the device.

Conclusion

The P51-75-S-H-MD-20MA-000-000 pressure transducer is an ideal choice for a range of industrial applications due to its rugged construction and excellent shock and vibration resistance. It utilizes a piezoresistive strain gauge and Wheatstone bridge configuration to accurately and reliably measure and record pressure data. This transducer is a reliable and precise device, suitable for a range of industrial applications.
