MPXV5004DP Pressure Sensor

[Click the image to enlarge it]

MPXV5004DP is a monolithic silicon pressure sensor from Freescale semiconductor that is a highly sensitive implanted strain gauge. It uses advanced micromachining techniques, bipolar processing, thin-film metallization, useful for accurate pressure sensing. The pressure range provided by this sensor is 3.92 kPa at 400mm H2O. It works with a nominal 4.75V to a maximum of 5.25 VDC supply voltage. However, it typically works with 5.0V DC voltage and requires a maximum of 10mAdc current. The sensitivity is 1.0V/kPa.

 

It provides an accuracy of ±1.5 %VFSS with autozero up to 100 mm H2O and ±2.5 %VFSS with autozero from 100 to 400 mm H2O, and ±6.25 %VFSS without autozero from 0 to 400 mm H2O.

MPXV5004DP Pressure Sensor - Overview

The pressure sensor is made using a Thermoplastic case. It uses differential sensing elements that are isolated from the environment by Flurorosilicone gel. It has an internal circuit that uses thin-film temperature compensation and calibration circuitry to calibrate the sensor automatically. Below images are showing the Output vs pressure differential with and without autozero.

MPXV50004DP Interfacing Diagram

The pressure sensor is designed for microprocessors or microcontrollers that have ADC (Analog to Digital Converter). It provides output voltage in proportion with the pressure sensed by the sensor.

 

However, proper power supply decoupling of the sensor is also required. The below image is providing a detailed interfacing diagram with any microcontroller unit that has the ADC features inbuilt. If ADC is not available, one can use an external ADC IC to convert the analog data into digital formats.

In the above image, three decoupling capacitors are used. Out of these three, two are used in the power line and the other one is used in the output.
