3. Permanent downhole gauge - Wikipedia

   en.wikipedia.org/wiki/Permanent_Downhole_Gauge

   A permanent downhole gauge (PDG) is a pressure and/or temperature gauge permanently installed in an oil or gas well. [1] These gauges are typically installed in the tubing in the well and can measure the tubing pressure, annulus pressure, or both.

8. Mercury pressure gauge - Wikipedia

   en.wikipedia.org/wiki/Mercury_pressure_gauge

   An open (differential) mercury pressure gauge. A mercury pressure gauge is a type of manometer using mercury as the working fluid. The most basic form of this instrument is a U-shaped glass tube filled with mercury. More complex versions deal with very high pressure or have better means of filling with mercury.

9. Hot-filament ionization gauge - Wikipedia

   en.wikipedia.org/wiki/Hot-filament_ionization_gauge

   The low-pressure sensitivity of hot-cathode gauges is limited by the photoelectric effect. Electrons hitting the grid produce X-rays that produce photoelectric noise in the ion collector. This limits the range of older hot-cathode gauges to 10 −8 Torr and the Bayard–Alpert gauges to about 10 −10 Torr. Additional wires at cathode potential ...
