Pressure Sensors, Transducers

The MPX5100D is a high-performance, reliable, and accurate pressure sensor which offers low cost and low power consumption for the operation of multiple pressure measurements. It is widely used in medical, automotive, industry, or environmental applications because of its capability to measure absolute or gauge pressure. It is capable of taking readings at any given Pressure value and is used for controlling and monitoring pressure for both large and small scale applications.

The MPX5100D employs a strain gage bridge sensor which combines two sensors to measure absolute or gauge pressure. Each sensor is made up of four active strain gages which are arranged in a Wheatstone bridge configuration. The resulting output is proportional to a change in pressure and is output as an analog voltage, typically centered around 2.5 volts. The MPX5100D is specially designed for sensitivity and linearity and is capable of measuring absolute pressure from 0 to 5.00 PSI and is calibrated with a standard offset of zero.

The MPX5100D is usually available in a range of sizes, from 1/8 inch to 2 inch. These sizes are suitably equipped with digital and analog outputs, which enable the user to connect the device to either a digital or analog controller, depending on the application. The analog output is available from a specified range, typically from 0.5v to 4.9v.The digital output is also available from 0 to 5 VDC.

To ensure accurate readings of pressure changes, the MPX5100D has built-in temperature compensation. This keeps the sensor from shifts in any temperature environment within the specified temperature range. To achieve maximum performance and longevity, the sensors should be calibrated using standard atmospheric pressure and temperature conditions.

The MPX5100D is used in a wide range of applications due to its high accuracy, reliability, and cost-effective design. It is well suited for applications such as gauging pressure changes in fuel tanks, controlling compressors, monitoring air pressure in tires, monitoring pressure in control valves, monitoring water levels, and controlling the pressure of hydraulic systems.

The working principle behind the MPX5100D is simple. When a pressure wave, such as air pressure, passes through the sensor, the strain gage elements that make up the Wheatstone bridge are distorted by the pressure and the resistance of the elements vary accordingly. This results in a change in the bridge’s output voltage, which is then amplified and used to measure the pressure changes. The amplified voltage is then used to calculate the pressure value.

In conclusion, the MPX5100D is an economical, reliable and accurate pressure sensor for multiple applications. Its Wheatstone bridge design responds quickly to pressure changes and its built-in temperature compensation feature ensures reliable readings in a wide range of applications. It is reliable, easily maintained, and affordable.
