The PENNINGVAC Sensor gauges are passive cold‑cathode sensors designed for reliable high‑vacuum measurement in demanding industrial and research applications. Using Penning cold‑cathode technology, the sensors deliver stable performance while remaining insensitive to air inrushes, vibrations, and contamination, making it ideal for harsh vacuum environments.

As a passive gauge, the PENNINGVAC sensor contains only the measuring element and must be operated with a compatible external controller. Its rugged construction, exchangeable cathode, and easy cleaning support long service life and reduced maintenance effort.
