CPC 4000 Pressure Controller

The model CPC4000 industrial pressure controller offers a broad pressure range from -1 … 210 bar (-15 … 3,045 psi). This instrument is available as a desktop or as a 19" rack-mounting kit. It can have up to two reference pressure sensors and an optional barometer for displaying barometric pressure or be used to emulate gauge or absolute pressure.

The instrument can have up to two internal pressure sensors and the ranges for each reference pressure sensor are determined by the customer within the allowable range.

Depending on the application, the operator can choose between three set-point methods:

  1. Direct entry of the pressure value (set point) which will be controlled via touchscreen keypad.
  2. Define steps to reach the desired pressure value by either defining fixed pressure increments or a percentage of span value.
  3. User-defined test sequences via external software, e.g. WIKA-CAL, or interface commands.

On request, complete mobile or stationary test systems can be manufactured. There is an IEEE-488.2, RS-232, USB (along with an optional USB-WiFi adapter) and an Ethernet interface for communication with other instruments, and thus the instrument can be integrated into existing systems.
