The AGC302 vacuum gauge controller is a power supply and readout instrument offered specifically for the InstruTech active vacuum gauge series WGM701 pirani-cold cathode combination gauge, CCM502 cold cathode gauge, PCM301 pirani-capacitance combination gauge, CDM900 capacitance diaphragm gauge (CDG) and other brands of CDGs. Note that the vacuum gauges listed above do not necessarily require the AGC302 to operate. These gauges provide analog output signals that can be directly interfaced with user’s control system. As such, AGC302 is recommended only when a panel/rack mount display installation and/or when setpoint relays and serial communications is required for the above gauges.
