Many vacuum applications operate only within a specific pressure range. In order to operate such vacuum systems efficiently, the total pressure must be measured reliably. The analog vacuum gages in the ActiveLine have been upgraded to the latest state-of-the-art with a successor model to the Pirani/Bayard-Alpert PBR 260, the PRB 360. This new Pirani/Bayard-Alpert gage covers the pressure range from 5 × 10–10 to 1,000 hPa. Due to its compact design, the gage provides a space-saving way to incorporate it into vacuum process systems, analytical instruments, leak-detection systems and other applications. Two filaments offer enhanced operating reliability, process control and longevity. — Pfeiffer Vacuum GmbH, Asslar, Germany
