Leybold Vakuum PEG050 vacuum sensor

The Leybold Vakuum PEG050 is a cold‑cathode Penning gauge used to measure vacuum levels from 1 × 10⁻⁹ to 10⁻² mbar in industrial chambers and semiconductor processing equipment. Common failure modes include high‑voltage supply degradation (anode potential drift), cathode sputtering leading to loss of sensitivity, and overload damage when exposed to pressures above the 6 bar limit. First‑check diagnostics: verify the ±kV power supply output and insulation resistance; inspect the gauge housing for corrosion or mechanical damage; review any error codes from the connected controller for over‑pressure or high‑voltage faults.[oss-gpt-20b] Post Comment
