Cold cathodes 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 transducers VSI (cold cathode) and VSM (Pirani / cold cathode) systematically reduce the high voltage of their cold cathodes in high pressure ranges, ensuring a significant ...
