AP & AG Fujikura Pressure Sensor Overview
Pressure Medium: Air/Gas
Sensor Type: Gauge
Supply Voltage: Under 5V
Output Signal: Voltage, Digital
Pressure Range: 3-300 psi
Kind: Board Level

The AP/AG pressure sensor series from Fujikura is composed of a silicon piezeoresistive pressure sensing chip and a signal conditioning integrated circuit. The low-level signal from the sensing chip is amplified, temperature-compensated, calibrated and finally converted to digital data that is proportional with the applied pressure. Gauge pressure sensor. The AG version is in a surface mount package. Pressure ranges include: 25 kPa, 50 kPa, 100 kPa, 200 kPa, 500 kPa and 1 MPa. 3 models are available: AP2/AG2 with compensated analog output, AP3/AG3 analog output with threshold detection, and AP4/AG4 with a digital output.


  • 3 mm or 6 mm pressure port for AG models, surface-mount
  • 3 mm or 6 mm port, dual-in-line package AP, barbed port version available (APB2)
  • Various pressure ranges from 0-25 kPa up to 0-1000 kPa, depending on model
  • Pressure type: Gauge pressure / Gauge negative pressure
  • Pressure media: non-corrosive gases
