Vakuumtransmitter VCP63MV / Vacuum Transducer VCP63MV

100% Robusta – Pirani with platinum rhodium Helix

The Pirani sensor in the VCP has a platinum rhodium filament. The new sensor is thus not only suitable for corrosive gas applications in a range of 100 … 5e-4 hPa. The relatively smooth surface of this material reduces deposits of oil vapors or other contaminations and therefore ensures a particularly high durability of the filament which has been verified in field tests with especially critical applications. The sensor can even withstand steam pressure sterilizations.

By having processed the nearly indestructible platinum rhodium alloy in the shape of a helix for the first time the VCP Pirani, which works with the patented impulse ramp principle, achieves an excellent precision as well as the high resolution and temperature stability that are well known from the Thyracont standard Pirani. The feedthrough is metal sealed and a stable, interference-free metal casing ensures optimum protection for the compact transducer even with rough application conditions.
Measurements are output as a logarithmic 0-10 V signal and can thus easily be processed in system control.
