Technology
Low Cost of Ownership
Gauge The IGM402 Hornet ionization vacuum gauge module
provides the basic signal conditioning required to turn the gauge
into a complete measuring instrument. It incorporates numerous
design features to enhance performance and reduce cost. The
electrometer circuit auto zeroes to ensure that the readings are
not subject to temperature drift, eliminating the need for
unnecessary, expensive circuitry which further reduces the cost.
Controller The compact modular design with the built-in controller
and display operates three different gauges without requiring
expensive external controllers.
Multiple Gauges The IGM402 Hornet is capable of operating two
external convection vacuum gauges simultaneously.
Full Range Measurement The IGM402 Hornet can combine the
vacuum measurement from the ion gauge and a convection gauge
to provide full range measurements from 1 x 10-9 Torr to 1,000
Torr, or simply operate the ion gauge and the two convection
gauges as individual gauges.
Display The standard built-in bright OLED display provides a
convenient user interface for setup and operation of the vacuum
gauges. The display screen can show all three measurements on
the same screen or display them sequentially. Service screens
allow monitoring of filament operation. Error messages are
displayed for several common fault conditions.
Operation The operation of the gauge including degas, filament
on/off and emission current is set by the front panel push buttons,
digital inputs or RS485 commands.
Sensor For general vacuum applications, dual yttria coated
filaments are offered for use with air and inert gases such as N2,
argon, etc. Dual tungsten filaments are available for use with
gases that may not be compatible with yttria coated filaments.
Space No rack space required. The modular design negates the
need for expensive and limited rack space.
Cabling Cost The cabling cost to connect a nude/glass ionization
gauge to a rack-mount controller can be excessive and installation is
time consuming. With the IGM402 no ion gauge cable is required
and one 10 ft. convection gauge cable is included.
Sensor Replacement Many full range combination gauges provide
measurements from atmosphere to high vacuum with multiple
sensors built into one assembly. A sensor failure may require
replacement of the entire sensor assembly often approaching 50%
of the initial cost of the vacuum gauge itself.
The IGM402 Hornet provides an alternative to these other gauges
by combining the vacuum measurements from the ion gauge and
one of the convection gauges to provide a full range gauge. A
sensor replacement requires only the replacement of the damaged
sensor and not all the other sensors at once.
The IGM402 Hornet sensor assembly can be easily replaced in the
field.
Additional Point of Use In addition to the ion gauge and one
convection gauge, the IGM402 Hornet can provide vacuum
measurements from a second convection gauge without the need
for another expensive controller. This results in significant cost
savings for monitoring the foreline or an additional point of use.
