Advantages

  • Significantly better resolution in the range above 100 Torr. [5]
  • The power consumption is drastically reduced compared to continuously operated Pirani gauges.
  • The gauge's thermal influence on the real measurement is lowered considerably due to the low temperature threshold of 80°C and the ramp heating in pulsed mode.
  • The pulsed mode allows for efficient implementation of modern microprocessor technology.
  • It will useful up to 10^-4 torr.
Disadvantages
  • Increased calibration effort
  • Longer heat-up phase
  • It is not useful at low pressure(below 10^-4torr)
