VacPuc Releases New Gauge Pressure Feature

VacPuc (Auckland, New Zealand), the manufacturer of innovative wireless, batteryless vacuum measurement solutions, is excited to announce the release of a new gauge pressure feature. This allows users to measure vacuum in gauge pressure in addition to the existing absolute pressure mode.

VacPuc users can now seamlessly switch between absolute or gauge pressure modes, with all historical records automatically converted. No additional hardware is required and all existing VacPucs are compatible with this new feature.

Gauge pressure is the pressure measured relative to the local atmospheric pressure (atmospheric pressure = 0 mbar/0"Hg, full vacuum = -1013mbar/-29.9"Hg at sea level), whereas absolute pressure is measured relative to full vacuum (atmospheric pressure = 1013mbar/29.9"Hg at sea level, full vacuum = 0mbar/0"Hg)

VacPuc strives to innovate rapidly and respond to customer needs. This new feature is a direct response to customer requests from environments where standard operating procedures and processes have been established using gauge pressure measurement, but there is also the desire to take advantage of VacPuc's unique wireless and batteryless technology that does not require a through bag penetration.

The new VacPuc app is available free of charge in both the Apple App Store and Android Play Store. VacPuc pressure sensors are available worldwide from a range of local distributors.

FAQ

• How does a VacPuc measure gauge pressure?
  • A VacPuc measures gauge pressure by measuring both the absolute pressure of the VacPuc and the phone's internal pressure sensor and calculating the difference.
• What happens if my phone doesn't have an internal pressure sensor?
  • Most modern phones have an internal pressure sensor, but for those without, there is the option to manually set the local atmospheric pressure. However, this should be used with caution as the local atmospheric pressure varies with weather and altitude.
• Do I need to upgrade my VacPucs?
  • No! No hardware change is required, just an update to the latest app version, which in most cases happens automatically overnight.
• How accurate is the gauge pressure measurement?
  • Because the gauge measurement utilises two independent pressure sensors, the error is the combined error of both sensors so is nominally +/-4mbar compared with +/-2mbar for absolute pressure measurement. However this does depend on the accuracy and condition of your phone internal pressure sensor.
