PENNINGVAC-Transmitters PTR are active sensors (pressure to voltage converters) with old cathode sensors based on the principle of the inverted Penning. Here the pressure is measured through a gas discharge within a gauge head whereby the gas discharge is ignited by applying a high tension. The resulting ion current is output as a signal which is proportional to the prevailing pressure. These sensors offer a wide measurement range of 10-9 to 10-2mbar (0.75·10-9 to 0.75·10-2 Torr).
