The Inficon/Leybold Center One 235002 is a single-channel vacuum gauge controller engineered for precise pressure measurement and system control in vacuum applications. This benchtop unit interfaces with active Leybold sensor series and provides real-time monitoring with adjustable switching thresholds, making it suitable for both standalone operation and integration into larger vacuum systems.
## Technical Specifications
**Model:** Inficon/Leybold 235002 Center One
**Type:** Single-Channel Vacuum Gauge Controller
**Regional Designation:** USA and Japan
**Measurement Units:** mbar, Torr, or Pascal (field-selectable)
**Firmware:** BG 509 763 -G
## Key Features
• Adjustable switching threshold for process control and automation
• Analog output: 0-10 Volt chart record input for data logging and external instrumentation
• RS232 C serial interface for remote monitoring and control
• Compact benchtop enclosure with flexible mounting options
• Mains power connector with widerange supply capability (90–250 V, 50–60 Hz)
## Sensor Compatibility
The 235002 controller supports active sensors from four Leybold product families:
• CERAVAC series (capacitive diaphragm sensors)
• THERMOVAC series (thermistor sensors)
• PENNINGVAC series (cold cathode ionization sensors)
• IONIVAC series (hot cathode ionization sensors)
This broad compatibility enables deployment across applications spanning from atmospheric to ultra-high vacuum ranges without requiring separate controller hardware.
## Typical Applications
• Vacuum pump process monitoring and control
• Chamber pressure regulation in deposition and etching systems
• Leak detection and diagnostics
• Multi-stage vacuum system supervision
• Laboratory and industrial vacuum instrumentation
## Integration & Mounting
The compact form factor accommodates three deployment scenarios: standalone benchtop operation, rack-mount integration, or control panel integration. Serial communication via RS232 C enables integration with supervisory systems, while the 0–10 V analog output provides hardware-independent chart recording and external relay logic compatibility.
