The patented TELEVAC Cold Cathode Ion Sensors have proven accuracy at ultra-high vacuums. They are highly sensitive and will maintain their discharge to much lower pressures. Moreover, while other sensors, such as Bayard-Alpert, experience X-ray-induced errors, TELEVAC Cold Cathode sensors produce no X-rays as part of the measuring process. Furthermore, there are now electron-stimulated desorption errors.
TELEVAC Cold Cathode Sensors are particularly advantageous in aggressive chemical or heavy industrial environments – there is no filament to degrade or burn-out. While Bayard-Alpert sensors are typically tossed out in industrial processing applications, a TELEVAC Cold Cathode Sensor is simply cleaned for like-new performance.
