Description

Absolute Pressure 1000 mbar to 1 x 10-4 mbar (=hPa), 750 - 1 x 10-4 Torr

The VSP63 is based on a new, patented measurement principle. The well proven Thyracont impulse Pirani sensor provides a larger measuring range with higher resolution. The advanced VSP63 uses an optimized temperature compensation. Accuracy and stability have been further improved.
Analog, logarithmic output signal VSP63MA4: 4-20 mA (three wire),
VSP63MV: 1.5 - 8.5 V.

Benefits

  • High reliability, excellent reproducibility
  • Extremely compact, designed for industrial applications
  • Wide measuring range, high resolution in the rough vacuum range
  • Filament, protected by a metal screen, provides good resistance against oil and solvent vapors
  • Precise push button digital adjustment on zero pressure and atmosphere
  • Low power consumption
  • Reduced self-heating of the measuring chamber because of impulse mode
  • Suitable for UHV applications due to the metal sealed stainless steel sensor

Typical Applications

  • Analysis instruments
  • Coating plants
  • Freeze drying , lyophilization
  • Vacuum furnaces
  • Operational control of roughing pumps and vacuum plants
  • Leak tests
  • Process engineering
