State-of-the-art vacuum gauges for laboratory and industrial operation have to meet high standards in terms of gauge head resistance to chemicals, reliability in rugged applications and operator-friendly interfaces. VACUUBRAND has a comprehensive range of electronic measuring instruments for the range of atmospheric pressure to 5 x 10-9 mbar. A lot of applications in the laboratory call for electronic vacuum control, that is, constantly adapting the pump´s volume flow rate to process requirements.
The maximum volume flow rate of the unregulated pump can be changed in various ways:
Cyclically turning the pump on/off (with the VNC 2 controller or the CVC 3000 controller with module VMS-B)
Cyclically opening/closing an in-line solenoid valve (CVC 3000 or VNC 2) or
Changing the pump´s motor speed continuously (VARIO® pumps in connection with CVC 3000 or VNC 2 VARIO)
