The 500101-2S-R4G-M Cold Cathode Gauge with Display features a 2.75 inch CF flange and a 1x10-10 to 1x10-2 Torr vacuum measurement range with mbar units. An included RS-485 communications interface and analog output signal features programmable off state, start point, and slope. Two programmable set point relays are also included. The included digital display can display pressure, USB connectivity, RS-485 address, remaining lifetime, and self diagnostics status. The 500 series incorporates the latest technology with modern design techniques to provide highly reliable and long life vacuum measurement across a wide pressure range. The modular design integrates gauge and control electronics in one convenient package. Cold cathode technology traditionally provides longer lifetime than hot cathode because there is no filament to burn out, but the tradeoff was reduced accuracy. The Series 500 Cold Cathode Gauge (CCG) defines a new accuracy standard based on innovative technology and time-tested calibration techniques. In addition, there has never been a good way to determine when a cold cathode gauge is worn to the point that its accuracy has significantly degraded. With a new patent-pending method of determining the pressure dosage over time and combining that with a user-selected environmental factor, the CCG Series 500 provides an indication of when the gauge needs to be serviced or replaced.
