    A gauge that measures the internal pressure (P) in powder-filled evacuated panels (PEPs) is described. PEPs are superinsulators consisting of high thermal resistivity powders encapsulated in hermetically sealed flexible barriers enclosing a vacuum. To measure P, the gauge supplies a vacuum to...
