Introduction

The 77031-00000100-01 pressure sensor is a cost-effective solution for industrial applications. This pressure sensor is accurate and provides accurate feedback on measurements at a given pressure. It is a pressure transducer capable of measuring differential pressures between 100 mbar and 1000 mbar (1 bar abs) and provides precise and repeatable measurement. In addition, the transducer has excellent long term stability.

Composition & Construction

It is an all-in-one transducer that combines large and robust mechanical parts for its construction. It includes the pressure sensor, a glass to metal seal housing and several electrical connections. The pressure sensor is designed as a piezoresistive unit which has a bridge circuit with full Wheatstone bridge. It has a large diaphragm with a steel diaphragm made of nickel plated, high alloy steel. The diaphragm can endure high temperature ranging from -40º C to 120º C. The glass to metal sealed housing is hermetically sealed with all external parts in stainless steel, which ensures tight sealing of the transducer. This type of construction also allows for excellent long term stability and reliability.

Applications

The 77031-00000100-01 pressure transducer is a cost effective solution for industrial applications. It is ideal for applications where accurately measuring pressure with extreme temperature is necessary. It has applications in measuring both differential and absolute pressure. It can be used in oil and gas, power generation, aerospace, industrial automation, automotive and marine applications.

Working Principle

The working principle of the 77031-00000100-01 is based on the Bourdon effect. The Bourdon effect is the phenomenon of a pressure differential being forces on a diaphragm, lifting it, and producing an electrical signal. This effect is hindered by the non-stretchable diaphragm as it presses against the bourdon tube. The diaphragm stretches, by causing the diaphragm to bow, resulting in a change in resistance of the piezoresistive bridge circuit in the transducer. This change in resistance is then translated into an electrical signal and sent to an analog-to-digital converter where it is converted from analog to digital data for further use.

Advantages and Disadvantages

The 77031-00000100-01 pressure transducer has several advantages which include its high accuracy, excellent long term stability, robust construction and its ability to measure both differential and absolute pressure. Its drawbacks include its limited pressure range and its reliance on analog-to-digital conversion for data processing.

Conclusion

The 77031-00000100-01 pressure transducer is a cost-effective and precise solution for measuring pressure in industrial applications. It is simple and affordable in design, allowing for excellent performance in numerous applications. Its ability to measure both differential and absolute pressure, and its excellent long term stability make it an ideal choice for several industrial applications, such as oil and gas, power generation and aerospace. The working principle used by it is based on the bourdon effect, which relies on a diaphragm translating pressure into an electrical signal. Its advantages and disadvantages should be weighed carefully before deciding on a pressure transducer for any particular application.
