IGC100 Ion Gauge Controller
The IGC100 is a high-accuracy vacuum gauge controller that offers pressure measurement and process automation never before available in a single instrument. It measures pressure from Bayard-Alpert ionization gauges, convection-enhanced Pirani gauges, and capacitance manometers providing uninterrupted pressure readings from 1000 Torr to UHV.
The IGC100 has a touchscreen display that can present data in a variety of formats including pressure versus time curves. There are built-in relays for process control, and several multipurpose input/output ports. The IGC100 is also fully
The IGC100 is designed to be a highly accurate, stable controller. Its low noise, auto-ranging electrometer delivers high accuracy pressure readings into the UHV range.
Pressure vs. Time Mode
The IGC100 has a large, back-lit LCD touchscreen display—new to vacuum gauge controllers. The instrument shows large numeric readings from each gauge (easily read from across the room), and can also display readings in bar graph or trend format. The screen is updated twice a second and results are presented in units of Torr, mbar, bar, Pa or microns. The IGC100 also displays pressure versus time curves (chart recordings), allowing you to follow pump down and venting cycles and to keep track of your vacuum system's performance.
IGC100 data is continuously logged into memory. There is a real-time clock with date for precise time stamps. In addition to pressure readings, you can log the ADC voltages and relay activity. Data can be viewed on the IGC100 or downloaded to your computer for further analysis.
The IGC100 has an optional Ethernet interface with embedded web-server hardware that makes your controller fully

Useful I/O Ports
The IGC100 has four auxiliary analog input/output ports. When configured as inputs, the ports can be monitored on the front panel or read through the GPIB,
The ports can also be configured as analog outputs with a voltage range of ±12 VDC, and can be used to send control voltages to other devices.
Powerful Process Control
The IGC100 does more than simply measure pressure. It can also be an eight channel process controller. There are eight relays, with corresponding TTL outputs, that can be used to control your vacuum system. They can be set by gauge pressure, status conditions (gauge on/off, filament on/off, etc.), the system clock, the analog I/O ports, or TTL input signals. The relays and TTL outputs can also be manually controlled from the front panel, and the status of all eight channels can be displayed.
Additionally, there are twelve dedicated TTL inputs for triggering functions like gauge on/off, filament on/off, degas, ion gauge lockout, etc. All process control events are time stamped and recorded in memory, and can be viewed at any time. User-programmable audible alarms and text messages can provide advance warning of potential problems.
The IGC100 can be set to automatically turn on an ion gauge once a Pirani gauge has reached a preset pressure level. If a UHV Pirani gauge is used in the same high-vacuum chamber as the ion gauge, you can make uninterrupted pressure measurements from atmosphere to UHV. In the event of overpressure, the IGC100's built-in filament protection algorithm, with user-programmable set point, immediately turns off your gauge filament.
Despite its many features, the IGC100 is easy to use. The menu based interface is intuitive, and parameter entry is quick and simple. And of course, there is interactive help for all functions of the instrument. There are dedicated front-panel buttons for filament emission, degas, and filament auto-start, and LEDs indicate their status. The IGC100 is compatible with virtually all Bayard-Alpert ion gauges including glass tubulated, nude, nude-UHV, STABIL_ION®, and MICRO_ION®. You can select from a variety of standard gauge configurations or program your own.
You can also assign a location name to each gauge, which is then displayed on the front panel of the unit. No more messy, confusing stickers on the face of your instrument. There are no DIP switches, trim pots or thumb-wheel adjustments in the IGC100youll never need to open the box.
A sensor on/off function has been added so you can shut down your Pirani gauges in the presence of flammable gases without having to physically disconnect them from the controller.
Password protection is provided to keep casual users from accidentally altering important parameters.
A high-level command set, along with an
SRS supplies a wide range of ion gauges. These include tubulated and nude designs with a variety of mounting options, and a choice of tungsten (W) or thoriated-iridium (ThO2/Ir) filaments.
We also offer a convection-enhanced Pirani gauge (PG108). PG108 gauges offer a measurement range that extends from 1000 Torr to
