Why Dual-Channel Architecture Transforms Pressure Control
Traditional multi-controller setups require multiple units, complex wiring, and synchronization, increasing cost and risk. The DoublePC™ consolidates all control into one intelligent unit, offering:
- True Dual-Zone Regulation: Two fully independent pressure channels with separate setpoints.
- Space-Optimized Design: Up to 70% smaller footprint compared to dual single-channel controllers.
- Single Point of Control: Eliminates inter-unit communication failures for enhanced reliability.
- Streamlined Integration: Unified power supply and communication interface simplifies system setup.
- Lower Total Cost of Ownership: Reduced hardware, maintenance, and installation expenses.
How DoublePC Benefits Your Process
- Enhanced Accuracy: ±0.08% FS repeatability ensures consistent results.
- Reduced Downtime: Ultra-low internal and external leakage protects your process.
- Flexible Integration: Single unit controls two zones, minimizing wiring and rack space.
- Scalable Solutions: Dual-range capability adapts to low-pressure precision and high-pressure requirements.
- Process Confidence: Temperature-compensated sensors maintain stability in fluctuating environments.

Frequently Asked Questions
How do I select the optimal pressure range?
Use your maximum expected working pressure plus 20–30% margin. Dual-range options are available for low/high resolution requirements.
What maintenance is required?
Minimal: routine visual inspection, annual calibration checks, occasional leak testing. Internal servicing is not needed during warranty.
Is it suitable for ultra-high vacuum (UHV)?
Yes. Low-outgassing ceramic sensors, minimal internal volume, and 2 × 10⁻⁶ sccm external leakage make it ideal. Bakeable options are available for degassing.
Can the controller be customized?
Yes. Options include extended pressure ranges, modified wetted materials, dual-gas calibration, custom communication protocols, and temperature enhancements.
