The 356005-YG-T Micro-Ion® Plus Vacuum Gauge Module with Digital Display features a Yttria-coated iridium filament material for vacuum measurement to 1 x 10-9 Torr. An additional Gold-plated tungsten heat loss sensor allows measurements to atmosphere. Communication is over DeviceNet and connection is made with a 2.75 inch CF flange fitting. The Micro-Ion® Plus Vacuum Gauge Module combines the new miniature Conductron Heat-Loss Sensor with proven Micro-Ion Gauge technology in the same vacuum envelope to extend pressure measurements from high vacuum to atmosphere. The Micro-Ion Plus design combines the control electronics and the gauge in a compact module that provides convenient high vacuum measurement and is easy to interface to a control system. The combination of two sensors in the same vacuum envelope saves space. Vacuum system control is simplified by using the heat-loss sensor to automatically turn-on and turn-off the ionization gauge. Convenient push button controls allow for module operation and adjustment of the two trip point relays without the need for electrical or computer interfacing.
