萊寶PENNINGVAC變送器#萊寶真空計#萊寶有源傳感器 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）.  | PENNINGVAC PTR 225
