Unscheduled downtime is avoided by using the second filament as a back-up until the gauge can be replaced during regular maintenance procedures.

Ultra-Clean Construction Micro-Ion gauges are designed, constructed, and processed to minimize outgassing. All components are vacuum fired and assembled in a Class 100 cleanroom environment. This assures rapid, repeatable response during vacuum chamber pumpdown.

Analog Output Version The basic transducer version provides an easy-to-use analog output signal that is linear with the logarithm of the pressure. An optional large green LED display provides point-of-use pressure indication.

Analog Output Signal Digital Interface Version Transducers are available with an RS-485 or DeviceNet interface for easy compatibility with computer controlled processes. The digital interface versions have a set point relay allowing for control of other vacuum equipment or to provide a safety interlock.

Replacement Gauge 355 Micro-Ion® hot cathode vacuum transducers features a unique, no tools required detachable vacuum gauge.  Please see 355 Micro-Ion® Hot-cathode Bayard-Alpert Vacuum Sensors for more information

Cooler Operation At only 8% of the power consumption of a glass or nude gauge, the Micro-Ion gauge generates much less heat, minimizing the disruption to a process or experiment.
