Cold Cathode Gauge | Cold Cathode Vacuum & Ionization Gauges

Features of the Cold Cathode Vacuum Gauge

The cold cathode vacuum gauge is a marvel of modern engineering, offering a unique combination of durability, accuracy, and versatility. Here’s why these gauges are essential in various applications:

• Wide Measurement Range: Cold cathode gauges can measure pressures from 10^-2 to 10^-11 mbar, making them suitable for a broad spectrum of vacuum applications.
• No Filament: Unlike hot cathode gauges, cold cathode ionisation gauges don’t use a heated filament. This design eliminates filament burn-out issues, enhancing reliability and reducing maintenance needs.
• Long Lifespan: The absence of a hot filament contributes to an extended operational life, making these gauges a cost-effective choice in the long run.
• Robust Construction: Cold cathode gauges are built to withstand harsh environments, making them ideal for industrial applications.
• Fast Response: These gauges offer quick response times to pressure changes, enabling real-time monitoring and control of vacuum systems.
• Low Outgassing: The cold operation results in minimal outgassing, ensuring more accurate measurements in ultra-high vacuum environments.
• Minimal Maintenance: With no filament to replace, cold cathode vacuum gauges require less frequent maintenance compared to hot cathode alternatives.
• Resistance to Contamination: These gauges are less susceptible to contamination from process gases, maintaining accuracy in various industrial processes.
• Compact Design: Many cold cathode gauges feature a compact design, allowing for easy integration into space-constrained vacuum systems.
• Digital Interface: Modern cold cathode ionisation gauges often come with digital interfaces, facilitating easy integration with control systems and data logging equipment.
