F32S23A

Working Principle of F32S23A

The F32S23A pressure transducer is based on a micro-diaphragm strain-gauge. This strain gauge is placed on the back side of a silicon diaphragm, which is exposed to the measuring medium. When there is a pressure variation, the diaphragm bends in proportion to the force applied, and its intrinsic elasticity supplies the restoring force.

The strain-gauge is comprised of a thin film of metal, which changes its electrical resistance when subjected to a mechanical strain.

The strain-gauge is connected to a Wheatstone Bridge circuit for signal conditioning and amplification. This bridge produces a single-ended output signal, which is proportional to the applied pressure. The amplified signal is then fed to an ADC (Analog-Digital Converter) integrated circuit, which produces a digital output signal for the user.

Advantages of the F32S23A

The F32S23A pressure transducer offers several advantages compared to other pressure measurement systems. It is cost-effective, being a one-stop device that combines a high-quality silicone diaphragm with the signal converter and digital interface.The device is also very small and lightweight, making it ideal for cramped OEMs.

It also offers an exceptional accuracy and stability under a wide range of temperatures. And its digital output makes it very easy to integrate into any control and monitoring system.

Conclusion

The F32S23A is an intelligent pressure transducer developed by Sensors and Transducers Ltd. It can be used to measure pressure, differential pressure, and vacuum pressure up to the full range of the transducer. It utilizes a precision micro-machined silicon diaphragm sensing element for high accuracy and reliability, and its digital output makes it very easy to integrate into any control and monitoring system.
