Active Inverted Magnetrom Vacuum Gauge

Edwards Active Inverted Magnetron 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. These vacuum gauges combine the gauge-head and controller in one compact active unit.

The AIM-X Gauge 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.

All gauges feature compact size for easy installation, a serial output and a replaceable sensor tube. They are also CSA and C/US approved as well as fully RoHS compliant due to their lead-free construction.
