Electro pneumatic pressure controller PRO PC

An electro pneumatic pressure controller PRO PC is a precision pressure regulator that electronically converts a pre selected pressure quantity into a pneumatic pressure with the highest accuracy. Fluctuations in the supply as well as changing flow rates are precisely compensated. The device precisely regulates a preselected pressure. The pressure can be regulated in relation to the ambient pressure or to the absolute pressure (vacuum).

The system pressure display shows the measured value applied to the pressure sensor.

The pressure preselection signal is represented by the internal microcontroller or transferred to it as an external analog preselection voltage. The actual pressure value is measured with a high precision pressure sensor. The microcontroller corrects and scales the characteristic curve and prepares it for output via the interface for a PC or an automation device. The standard version of the device already has a USB interface. As further options RS232, CAN, Ethernet and RS485 are available. The communication can be done in all common protocols.

The pressure controller is supplied with a standard program with which customer-specific program sequences can be created. The program can be operated from any PC. Several pressure controllers can also be operated with one PC. The sequences can be stored on the pressure controller. Thus an individual test sequence is possible without a PC.

The PRO PC is only suitable for operation with gaseous, non-aggressive and non-flammable media such as dry air or nitrogen.

Application fields: production, development, research, calibration, simulation, testing technology

Measuring range: 0 … 50 mbar to 0 … 400 bar, absolute, relative or differential pressure. Also available up to 1500 bar in a modified version

Accuracy: +/-0.01% of full scale

Manual/ computer operation
The PRO PC can be controlled in both manual and remote mode (PC mode). In manual mode the unit is operated via the keyboard.

System pressure display
The system pressure display shows the applied pressure in bar or mbar absolute or relative.

The keypad is used for manual control of the PRO PC.

Up to 100 pressure points with rise/fall times can be stored in the device. Free programming of any sequences is possible via PC or automation devices.
