Pressure Sensors

Pressure sensors are devices designed to detect, measure and report the pressure, force, or tension of gases or fluids. They are used in a wide range of industries and applications, including water management, automotive systems, machine vision, and environmental monitoring. This article focuses on the ADP5100 pressure sensor and its application field and working principle.

ADP5100

The ADP5100 Pressure Sensor is a high-accuracy, low-power, single-axis, optical pressure/force sensor designed for use in a variety of applications. It has a selectable range of 0-50 mbar (±1 mbar) or 0-300 mbar (±3 mbar) with a linear output of 0-5.0 VDC. The sensor’s low power consumption makes it suitable for battery-powered applications, and its small form factor allows it to be easily integrated into most systems.

Application Field

The ADP5100 pressure sensor can be used in a wide range of applications and industries, including automotive, aerospace, machine vision, testing and process control, and medical. In the automotive industry, the sensor can be used for direct pressure measurement in modern cars’ electronic stability control systems, engine control modules, and emission control. In the aerospace industry, the sensor can be used to monitor and report pressure in a variety of airborne systems, such as the air compressor, fuel and oil tank, etc. In the medical field, the sensor can be used for patient monitoring systems, such as blood pressure, breathing, and heart rate monitoring.

Working Principle

The working principle of the ADP5100 sensor is based on optical measurement of the deflection of a diaphragm caused by the pressure of the enclosure. The sensor contains a lens, which focuses a light beam to the diaphragm. At predetermined pressure, the diaphragm deflects and the beam is deflected away from the sensors original position. The deflection is measured by a light sensitive detector and is used to determine the pressure in the system. The signal generated by the detector is then amplified and processed to output a 0-5.0 VDC signal, which is proportional to the pressure applied. The sensor is also capable of self-calibration in order to compensate for long-term drift and ambient temperature variations.

Conclusion

The ADP5100 Pressure Sensor is a highly accurate, low-power, single-axis, optical pressure/force sensor designed for use in a variety of applications. Its small form factor, proportional output, low power consumption, and self-calibration capabilities make it an ideal choice for use in automotive, aerospace, machine vision, testing and process control, and medical applications.
