<p>Micro-Pirani gauge vacuum gauges are described that use low-thermal conductivity support elements. A micro-Pirani gauge or vacuum sensor can include a heating element operative to heat a gas and to produce a signal corresponding to the pressure of the gas; a platform configured to receive the heating element, with the platform having a first coefficient of thermal conductivity; and a support element connected to a substrate and configured to support the platform with the heating element within an aperture disposed in the substrate, with the support element having a second coefficient of thermal conductivity, where the second coefficient of thermal conductivity is less than the first coefficient of thermal conductivity. Multimode pressure sensing including a micro-Pirani gauge are also described.</p> |
