MPXM2010GS 0 To 10kPa (0 To 1.45 PSI) Pressure Sensor Module

The MPXM2010GS silicon piezoresistive pressure sensors provide accurate and linear voltage output directly proportional to applied pressure. These sensors house a single monolithic silicon die with strain gauge and thin film resistor network integrated. The sensor is laser trimmed for precise span, offset calibration and temperature compensation. The series includes a strain gauge and thin-film resistor network integrated on each chip

 

Features

  • Temperature Compensated over 0 to +85 C
  • 0 To 10kPa (0 to 1.45psi)
  • Output 25mV Full Scale
  • Supply 10V DC (10-16V Possible)

Applications

  • Respiratory Diagnostics
  • Air Movement Control
  • Controllers
  • Pressure Switching

The resolution of the system is determined by the mm of water represented by each A/D count. As calculated above the system has a span of 226 counts to represent water level up to and including 40cm. Therefore, the resolution is:

Resolution=mm of water/Total # counts=400mm/127 counts=3.1 mm per A/D count
