WGM701 Wasp – Advanced Cold Cathode & Pirani Vacuum Gauge Module

The WGM701 Wasp combines inverted magnetron cold cathode technology with a Pirani sensor for reliable vacuum measurement across an ultra-wide range. Its compact metal design and sensor activation aid ensure faster cold cathode startup and robust performance.

Why Choose WGM701?
✔ Ultra-Low Magnetic Stray Field – Safe for instruments sensitive to external magnetic fields
✔ Interchangeable Dual-Chamber Design – Reduces maintenance and enhances durability
✔ Built-In Controller – Includes log-linear analog output and sensor status output
✔ Automatic Sensor Activation – Cold cathode engages when Pirani detects pressure below 9.10 × 10⁻³ mBar

Technical Highlights:

• Pressure Detection: Cold cathode + Pirani combination
• Pressure Range: ATM to 1.10 × 10⁻⁹ mBar
• Pressure Units: Torr / mBar / kPa
• Setpoint Accuracy:
  • 7.6 × 10⁻⁹ to 7.6 × 10⁻³ Torr: ±30% of reading
  • 7.6 × 10⁻³ to 75 Torr: ±15% of reading
  • 75 to 760 Torr: ±50% of reading

Ideal for high-vacuum applications, industrial systems, and research environments, the WGM701 Wasp delivers precision, ruggedness, and intelligent control in one compact module.
