Cold cathode with optimized durability

Cold cathode gauges – due to their physical characteristics – show increased abrasion in a pressure range higher than 1×10-4 mbar, caused by their inherent sputter effect. The new generation of our Smartline® vacuum transducer VSM (Pirani / cold cathode) systematically reduces the high voltage of its cold cathode in high pressure ranges, ensuring a significant longer lifetime of the ...
