Pressure Sensors, Transducers

The MPXM2053GS is an advanced solid-state pressure sensor used in a variety of applications including automotive, industrial, and medical. It can measure pressure in absolute, differential, and gauge equivalents from 0 to 5 psi with an accuracy of ±0.25%. The device’s high-sensitivity silicon resonant beam design makes it resistant to shock and vibration, and its wide temperature range (-40 to +205 °C) ensures reliable performance in a variety of harsh environments.

This device is well suited for applications such as enhanced oil recovery, natural gas processing, pipeline safety, and underground storage tank monitoring. It is also used for monitoring the pressure of engine fuel, coolant, and lubricating oil systems in automobiles and other vehicles. Additionally, the MPXM2053GS can be used to control air pressure in medical equipment such as respirators and ventilators.

Working Principle

The working principle of the MPXM2053GS is based on the piezoresistive effect, whereby electrical resistance of a material changes when it is exposed to mechanical stress. It utilizes a silicon resonant beam that acts as a diaphragm to detect and measure very small pressure changes.

When a pressure is applied, the beam flexes, and this causes a small change in electrical resistance. This resistance change is detected by the circuit and then converted into a proportional voltage. The signal is transmitted to a readout instrument, which indicates the pressure value on its display.

The MPXM2053GS is designed with an internal temperature-compensated voltage reference that enables it to maintain accuracy and stability over a wide range of temperatures. Its built-in anti-aliasing filter prevents noise and maintains accuracy within the specified bandwidth.

Conclusion

The MPXM2053GS pressure sensor is a reliable and robust device that is used in a variety of industrial and medical applications. Its high sensitivity and accurate measurement performance make it an excellent choice for device designers when accuracy and reliability are required. The device’s wide temperature range also makes it suitable for use in harsh environments.
