This sensor measures the total pressure on a system.

When the single port is left open, then the sensor measures the atmospheric pressure.

However when the sensor is connected to a sealed system, then it adds the system’s pressure effect (negative or positive) to the atmospheric value.



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

Earth Science-

  • Atmospheric pressure measurements
  • Altimeter


  • Boyle’s Law
  • Vapour pressure of liquids


  • Gas Laws


  • Range 1: 0 to 700 kPa Absolute (Resolution: 0.3 kPa)
  • Range 2: 0 to 100 psi (Resolution: 0.1 psi)

This sensor is suitable for experiments requiring a wider pressure range e.g. Boyles Law and Balloon burst investigations.

The sensor element has automatic internal temperature compensation so that changes in room temperature do not affect readings.

The user manual has a recommendation chart for the ‘best’ sensor to use for different gas pressure investigations.

Works with the following Dataloggers:

VHub4 and VHub8


Gas Pressure – Absolute

  • 0 to 700kPa Absolute (Resolution 0.3kPa)
  • 0 to 100psi (Resolution 0.1psi)
