Pressure Controller Options for Mechatronic Vacuum Valves
Integrated or external pressure controller for VAT mechatronic vacuum control valves offer a wide range of configuration options.
They convince through ...
- Very short response times
- Fast and precise pressure control
- Precise valve position control
- Learning algorithms for automated control optimization
- Digital and analog inputs for sensor signals
- Choice of local or remote control
- Integrated display for local status indication
Learning Algorithms for Automated Control Optimization
With the integrated learning function, the pressure controller independently adapt the valve control to the prevailing process conditions within defined limits. This increases the effectiveness of the valve control in terms of speed, conductance, and the avoidance of vibrations and shocks.
By operating the LEARN function – only needs to be performed once during start-up – the relevant system parameters are determined automatically. Due to the adaptive algorithm, the pressure regulator continuously adjusts to changes in gas flow or gas type, ensuring optimal pressure control at all times.
In position control mode, the valve plate can be moved to any position. Status and position are indicated via the 4-digit display.
VAT pressure controllers can be controlled with an external PC via Logic, RS232, RS485, DeviceNet®, Ethernet, Profibus, CC-Link or EtherCAT interface. For this purpose, VAT offers special configuration, control and diagnostic software for Windows, which is automatically loaded when a PC is connected to the controller.
The RS232 interface and the fieldbuses can also be used for digital signal input to close and open the valve. In addition, digital outputs are available for the signals "closed" and / or "open".
The control via the logic interface can be done optionally via digital and analog signals.
Since the pressure controllers are each designed for specific vacuum valves, you must first identify the corresponding valve type to find out which options are available for this valve type.
