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
