At a glance
A PLC with a tuned PID loop sets proportional valve pressure automatically while logging vibration — responsive and cost-effective.
PID control suits systems that are essentially linear and whose dynamics do not change over time. A PLC runs a tuned PID loop — proportional, integral and derivative terms — to automate what an operator would otherwise do by watching a gauge and turning a knob until the output settles.
The result is a responsive, relatively low-cost controller that meets the needs of modern industrial control systems.
Specifications
- USB control of the electro-pneumatic proportional valve pressure setpoint (analogue 4–20 mA); input current and actual valve output pressure can be calibrated
- Vibration readings logged to the PC; vibration sensor up to 6 G
- PC software loads editable product configuration files
