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).

莱宝真空计(Vacuum Gauge),又称规,是测量真空度或气压的仪器。一般是利用不同气压下气体的某种物理效应的变化进行气压的测量。在科研和工业生产中广泛使用。
按照真空计测量原理所利用的不同的物理机制,可将主要的真空计分为三大类,分别是利用力学性能、利用气体动力学效应和利用带电粒子效应的真空计。
利用力学性能的真空计典型的有波尔登规(Bourdon)和薄膜电容规;利用气体动力学效应的典型真空计有皮拉尼(Pirani)电阻规和热电偶规;利用带电粒子效应的典型真空计有热阴极电离规和冷阴极电离规。
