InstruTech Stinger Convection Gauge Series 211

InstruTech CVM211 “Stinger” Convection (Pirani) Gauge Module — Convection-Enhanced, Stand-Alone Vacuum Measurement

The InstruTech CVM211 Stinger is a convection-enhanced Pirani vacuum gauge module with a built-in controller and display—providing full-range vacuum monitoring from approximately 1 × 10^–4 Torr up to atmospheric pressure (~1000 Torr). This all-in-one design simplifies installation and makes it an excellent replacement for legacy Mini-Convectron® modules.

Key Benefits

• Expansive pressure range: Covers from ~0.0001 Torr to 1000 Torr—higher than conventional thermocouple gauges. :contentReference[oaicite:0]{index=0}
• Integrated electronics: Includes display, analog output, and setpoint relay—no external controller required. :contentReference[oaicite:1]{index=1}
• Drop-in Mini-Convectron® replacement: Compatible connectors and outputs make for seamless upgrades. :contentReference[oaicite:2]{index=2}
• Compact & robust: Reduced internal volume and surface area for faster pump-down and outgassing resistance; rugged design resists vibration and contamination. :contentReference[oaicite:3]{index=3}

Technical Highlights

• Measurement Range: ~1 × 10^–4 Torr to 1000 Torr (1.3 × 10^–4 to 1333 mbar). :contentReference[oaicite:4]{index=4}
• Analog Outputs: Choice of log-linear (1 V/decade, 1–8 V) or non-linear (S-curve, 0.375–5.659 V) analog output. :contentReference[oaicite:5]{index=5}
• Setpoint: One SPDT relay (1 A at 30 V DC/resistive) for pump control or alarms. :contentReference[oaicite:6]{index=6}
• Display: Bright multi-digit LED (varies by pressure range). :contentReference[oaicite:7]{index=7}
• Power: Operates on 11–30 V DC at ~2 W; protected from reverse/transient voltages. :contentReference[oaicite:8]{index=8}
• Fittings: Offers a wide range—1/8-in NPT, NW16/25/40 KF, Cajon 4VCR/8VCR, Mini-CF, Conflat, and more. :contentReference[oaicite:9]{index=9}
• Certifications: CE and RoHS compliant. :contentReference[oaicite:10]{index=10}

Applications

• Deposition systems, vent control, load-lock monitoring, and rough vacuum processing.
• Analytical and research setups needing compact, accurate vacuum feedback.
• Retrofits replacing Mini-Convectron® modules—same signals, lower cost, better performance.

Integration & Installation Tips

• Directly connect to PLCs or DAQs using the analog output—no extra controller needed.
• Mount horizontally below ~1 Torr for accuracy; orientation is less critical in lower vacuum. :contentReference[oaicite:11]{index=11}
• Ensure proper grounding and protect operators from relay/interlock hazards. :contentReference[oaicite:12]{index=12}
• Use correction factors when measuring gases other than air/N₂. :contentReference[oaicite:13]{index=13}

Frequently Asked Questions

Can the Stinger replace my Mini-Convectron®?

Yes. It uses the same 9-pin D-sub pinouts and includes matching analog and relay outputs for seamless swapping. :contentReference[oaicite:14]{index=14}

What’s the benefit of convection enhancement?

It extends the functional range beyond standard Pirani gauges—from ~10⁻⁴ Torr to full atmosphere coverage. :contentReference[oaicite:15]{index=15}

Is the analog output configurable?

Yes—choose either a log-linear or S-curve output to match your automation or monitoring requirements. :contentReference[oaicite:16]{index=16}
