Gas Pressure - Absolute, Barometer, Altimeter   Home / SmartQ Sensors  

Measures the absolute pressure of the system it is connected to. Range of 0 – 110kPa.

Gay Lussacs Law
Teaching applications:
  • Gay-Lussac’s law (Pressure vs. Temperature)
  • Weather studies / Changes in air pressure (Barometric pressure)
  • Altimeter

With the port left open the Sensor will display the value for atmospheric pressure (average 101.325 kPa). External diameters of the ports are tapered from 4.0 to 4.3 mm. Use with flexible tubing 3.0 to 3.5 mm internal diameter. These Sensors are not suitable for use with flammable gases.

  • Referenced to a pre calibrated vacuum zero
  • Gives the absolute pressure relative to a fixed zero
  • Temperature compensation of electronics


0 to 110 kPa Absolute
85 to 110 kPa Absolute (Resolution 0.1 kPa)
0 to 33 in Hg (Resolution 0.01 in Hg)
Altitude: -500 to 12,000 m (Resolution 4 m)
