InstruTech Super Bee CVM201 Convection Gauge

InstruTech Super Bee CVM201 Convection Vacuum Gauge Module

The **InstruTech Super Bee CVM201** is a convection-enhanced Pirani (thermal conductivity) vacuum gauge with a **built-in controller, OLED display, analog outputs, setpoint relays, and RS-232/485 communications**, offering an all-in-one solution for vacuum monitoring ranging from approximately **1 × 10⁻⁴ Torr up to atmospheric pressure (~1000 Torr)**—a vast measurement range rarely matched by standard gauges. :contentReference[oaicite:0]{index=0}

Key Benefits

• Broad pressure range: Covers from ~0.0001 Torr to 1000 Torr in one compact module—extending well beyond traditional Pirani limits. :contentReference[oaicite:1]{index=1}
• Standalone design: Combines sensor, digital display, signal processing, and outputs—no controller needed.
• Mini-Convectron® replacement: Plug-compatible with legacy Granville-Phillips hardware—same connectors, software commands, and pinouts. :contentReference[oaicite:2]{index=2}
• Flexible outputs: Offers dual analog outputs (linear, log-linear, or S-curve), two setpoint relays, and digital RS-232/RS-485 communication. :contentReference[oaicite:3]{index=3}
• Built for uptime: Reduced internal volume and surface area enhance pump-down speed; features like inlet mesh filters and RF shielding improve reliability. :contentReference[oaicite:4]{index=4}

Specifications at a Glance

• Pressure Range: ~1 × 10⁻⁴ to 1000 Torr (1.3 × 10⁻⁴ to 1333 mbar) :contentReference[oaicite:5]{index=5}
• Accuracy (N₂ gas):
  • 1 × 10⁻⁴ to 1 × 10⁻³ Torr: 0.1 mTorr resolution
  • 1 × 10⁻³ to 400 Torr: ±10 % of reading
  • 400 to 1000 Torr: ±2.5 % of reading

  :contentReference[oaicite:6]{index=6}

• Repeatability: ±2 % of reading :contentReference[oaicite:7]{index=7}
• Display: Bright OLED, 4-digit, selectable units (Torr, mTorr, mbar/bar, Pa) :contentReference[oaicite:8]{index=8}
• Outputs & Interfaces: Dual analog (linear, log-linear, S-curve), two SPDT relays (1 A @ 30 VDC), RS-232 & RS-485 serial :contentReference[oaicite:9]{index=9}
• Power: 11–30 V DC, ~2 W, protected against reversal & transients :contentReference[oaicite:10]{index=10}
• Construction: Gold-plated tungsten sensor, 304/316 stainless steel, glass, nickel, Teflon—even with low internal volume (~26 cm³) and surface area (~59.7 cm²). :contentReference[oaicite:11]{index=11}
• Mounting Orientation: Horizontal recommended above 1 Torr; orientation has minimal effect below that. :contentReference[oaicite:12]{index=12}

Applications That Benefit Most

• Retrofitting Mini-Convectron® modules in coating systems, load-locks, or vacuum ovens.
• Vent sequencing, vacuum packaging, and rough-to-full-range monitoring in process environments.
• OEM systems requiring space-efficient yet feature-complete vacuum sensing.
• R&D platforms where multi-unit convenience and fast feedback boost productivity.

Integration & Installation Tips

• Plug-and-play upgrade: Drop into Mini-Convectron® slots using existing cabling and software.
• Use correct analog format: Select linear for raw scale, log-linear for decade-based systems, or S-curve for smooth control integration.
• Mount horizontally above 1 Torr: Ensures accuracy—below 1 Torr, orientation becomes less critical. :contentReference[oaicite:13]{index=13}
• Grounding matters: Common in convection modules—wire to chamber ground for safety and signal integrity. (Use standard vacuum grounding practices.)

Frequently Asked Questions

Can the Super Bee replace Mini-Convectron® gauges directly?

Yes—same D-sub pinouts, outputs, relays, and software interface. It’s designed as a drop-in, lower-cost, higher reliability replacement. :contentReference[oaicite:14]{index=14}

What’s special about “convection-enhanced” sensing?

Beyond standard Pirani, convection currents improve heat transfer at higher pressures, extending sensing from deep vacuum to atmosphere with one gauge. :contentReference[oaicite:15]{index=15}

Are analog outputs configurable?

Yes—you can choose between log-linear (1 V/decade), S-curve, or linear configurations to best suit your control systems. :contentReference[oaicite:16]{index=16}
