Active Inverted Magnetron Gauge

Edwards Active Inverted Magnetron Gauge

Edwards Active Inverted Magnetron (AIM) Gauges provide accurate measurement over the vacuum range of 1x10⁻² to 1x10⁻⁹ mbar. These gauges have proved to be rugged and reliable in a wide range of applications, ranging from scientific instruments to industrial processes.

The AIM-X Gauge is an inverted magnetron gauge head and gauge controller combined into a single compact unit, and features a linear output for easy integration with a computer or PLC.

The XL variants have a very low external magnetic field, these are ideally suitable for use with sensitive analytical instruments or in applications where the gauge needs to be mounted in close proximity to a turbomolecular pump.

Drive electronics combined

in the gauge head which reduces the system cost and saves valuable rack space

Low output impedance and integral Faraday shield

provides high level of noise immunity and permits long cable runs (up to 100 m)

Low magnetic field version – XL

for sensitive applications, e.g. mass spectrometry and electron microscopy.

Interchangeable body tube

allows for rapid tube replacement without pre-calibration

CSA, CSA/US Approved

meets safety requirements for electrical equipment for measurement.
