Magnetron Gauge AIM
Description
Edwards Active Inverted Magnetron (AIM) Gauges provide accurate measurement over the vacuum range of 1 x 10-2 to 1 x 10-9 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.
