• Construction Materials: Molybdenum anode, Ni alloy components, alumina, stainless steel, and glass. Rugged and vacuum-ready. :contentReference[oaicite:11]{index=11}
• Internal Volume: ~22.8 cm³ (1.39 in³), aiding fast pump-down and system responsiveness. :contentReference[oaicite:12]{index=12}
• Temperature & Pressure Limits: Operates at +5 to +55 °C; bake-out capability up to 150 °C with electronics removed; withstands inert gas overpressure to 10 bar (145 psi). :contentReference[oaicite:13]{index=13}

Ideal Use Cases

• Compact UHV systems needing deep vacuum measurement in tight spaces.
• Analytical and scientific instruments such as mass spectrometers, surface-analysis chambers, and accelerator beamlines.
• Retrofitting legacy ion gauges with a modern, self-contained module.
• Systems sensitive to stray magnetic fields—like electron optics or microscopy setups.

Integration & Best Practices

• Activation control: Use a convection or Pirani-based gauge to trigger cold-cathode sensor activation at appropriate pressure to preserve sensor life. :contentReference[oaicite:14]{index=14}
• Signal handling: Direct the analog output to PLCs, DAQs, or control systems; monitor the status output for sensor health.
• Maintenance tip: Replace the sensor insert as needed—thanks to its modular design, servicing is quick.
• Mounting consideration: Designed to be installed in any orientation; ensure a clean, leak-tight connection. :contentReference[oaicite:15]{index=15}

Common FAQs

Does the CCM502 require a separate controller?

No—it includes internal signal conditioning. However, if you need setpoint relays or serial communication, consider the AGC302 controller. :contentReference[oaicite:16]{index=16}

What’s its measurement capability?

From about 7.6 × 10⁻¹⁰ Torr to 7.6 × 10⁻³ Torr, covering deep UHV ranges effectively. :contentReference[oaicite:17]{index=17}

Is it safe near magnetic-sensitive equipment?

Yes—its ultra-low stray field design allows placement near magnetic sensors and instruments. :contentReference[oaicite:18]{index=18}
