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. The patented Conductron Heat Loss Sensor is based on the understanding and insights gained in over 35 years of experience in making the industry standard Convectron® Gauge. The wide range, high performance and compact size make the Micro-Ion Plus Module a wise choice for pressure measurement on high vacuum systems.

Micro-Ion® Plus Gauge

• Compact Combination Gauge: Micro-Ion Plus combines the new miniature Conductron Heat-loss sensor with a Micro-Ion sensor in one gauge envelope, at less than 10% of the volume of a conventional ionization gauge.
• High Performance: The complete Micro-Ion design has been retained with the patented dual ion collector that increases the electron path length and ion collection efficiency, providing high performance in a small volume.
• Dual Ionization Sensor Filaments: Dual, burn-out resistant yttria-coated iridium filaments provide long gauge life. Unscheduled downtime is avoided by using the second filament as a back-up until the gauge can be replaced during regular maintenance procedures.
• Cooler Operation: At only 8% of the power consumption of a traditional glass or nude gauge, the Micro-Ion sensor generates much less heat to disturb a process or experiment.
• Robust All-Metal Design: Welded components, vacuum fired and assembled in a cleanroom environment, are enclosed in a stainless steel envelope to ensure sensor integrity.
• Port Shield: Protects the electrode assembly from damage during assembly or vacuum chamber maintenance, and provides a stable electrical environment for improved measurement performance.
• Wide Selection of Vacuum Fittings: Simplifies installation on your vacuum system.
• Replaceable Gauge: Gauge can quickly and easily be replaced using only a screwdriver.

Micro-Ion® Plus Module

• Wide Measurement Range: Allows vacuum system performance to be monitored continuously from 1x10-9 Torr (1x10-9 mbar; 1x10-7 Pa) to atmosphere.
• Simple Modular Design: Electronics and sensors are packaged together in one compact, easy to install module that eliminates the need for multiple gauges, cables, and electronics.
• Control System Simplification: The integral heat loss sensor automatically controls activation and deactivation of the ion gauge, eliminating the need for external control of the ion gauge.
• RS-485, Analog Output and Remote I/O: In addition to RS-485 communications and analog output, the module provides input control of gauge on/off, degas, atmospheric calibration, and keyboard lock along with outputs of gauge, filament, and degas status.
• Process Trip Points: Relay contacts allow control of other vacuum equipment and provide safety interlocking. Settings are adjustable through the local display interface, RS-485 or DeviceNet interface.
• Local Display/Interface (Optional): Setup time and diagnostics are improved with a green LED display and pushbutton interface that gives point-of-use pressure indication and local adjustment of process trip points.
• DeviceNet Interface Version: Provides high speed access to pressure measurement and easy configuration of gauge parameters.
• DeviceNet Network Power Flexibility: Gauge power can be supplied either through the DeviceNet micro connector or through a separate connector.
