<strong>Vacuum</strong> gauges and controllers<br />
<strong>Vacuum</strong> controller<br />
<strong>Vacuum</strong> controller VNC 2<br />
PERFORMANCE FEATURES<br />
■ on-demand control of process vacuum, cooling<br />
water and venting; special program <strong>for</strong> operating<br />
vacuum networks like VACUU·LAN ®<br />
■ easy changing of vacuum set points also during<br />
operation<br />
automatic or manual setting of the pressure<br />
■ switching interval (hysteresis)<br />
integrated relay <strong>for</strong> switching pumps on/off<br />
■ (except VNC 2 VARIO)<br />
■<br />
The vacuum controller VNC 2 makes automatic, on-demand vacuum control possible either via two-point valve control<br />
or by switching the pump on or off. The version VNC 2 VARIO offers continuous vacuum control with VARIO ® pumps.<br />
The integrated alumina ceramic diaphragm vacuum sensor is chemically resistant, and offers outstanding measuring<br />
accuracy independent of gas type. The VNC 2 vacuum controller is designed <strong>for</strong> precise and reliable control<br />
of recurrent routine jobs that do not require regular adjustment. It works with components compatible with the<br />
VACUU·BUSTM system. Special versions of the controller, e.g., <strong>for</strong> mounting into laboratory furniture, are available.<br />
