AIM-S-NW25
HVC-D14641000
The AIM Gauge is an inverted magnetron gauge head and gauge controller in a single compact unit. The gauge operates as a cold cathode ionisation gauge, in which pressure is measured indirectly as a function of the current that flows in a Townsend discharge maintained in the body tube.
The measurement range of the AIM Gauge is 1 x 10-8 to 1 x 10-2 mbar.
The AIM Gauge requires a 13.5 to 36 V d.c. power supply: it has a 2 to 10 V d.c. analogue output which is related to pressure.
The AIM Gauge is compatible with all of Edwards Active Gauge Controllers and with the appropriate versions of the Active Gauge Displays. Alternatively you can use an independent power supply for the AIM Gauge and you can read the AIM Gauge output signal with a voltmeter or an analogue-to-digital converter.
