How MicroVC Vacuum Controllers Work
MicroVC controllers combine precision sensors and electronically controlled valves to actively maintain vacuum levels:
- Precision Vacuum Sensors: Continuously monitor system vacuum with high accuracy.
- Electronic Control Valves: Make fine adjustments to stabilize pressure and maintain setpoints.
- Feedback Control Loop: Compensates for variations in system volume or environmental changes, ensuring stable and repeatable operation.
Note: Response time is influenced by the size of the vacuum chamber and valve configuration. Smaller volumes stabilize faster, while larger systems require slightly longer adjustment. Correct system matching maximizes performance.
Unlike conventional vacuum regulators that provide only coarse adjustments, the MicroVC delivers high-resolution, repeatable vacuum control, minimizing fluctuations and improving overall process reliability.
