The AP301 series medium pressure MEMS sensing elements from Merit SensorTM is ideal for OEM applications, offering available pressure ranges of between 100psi and 1000psi. The sensors utilise a piezoresistive Wheatstone bridge in a design that anodically bonds glass to a chemically etched silicon diaphragm. This pressure sensor series offers an operating temperature of −40°C to +150°C and a full scale output range of either 150mV or 175mv (depending on the pressure range). The AP301 series from Merit SensorTM products incorporate a proprietary Sentium® technology, developed to provide a best-in-class operating temperature range and superior stability.

  • Medium pressure MEMS sensing elements
  • Pressure ranges available 100psi, 300psi, 500psi and 1000psi
  • Absolute and gauge options available
  • Temperature range −40°C to +150°C
