DosiTorr SRG Transducer

The SRG Transducer is a process manometer based on Spinning Rotor Gauge (SRG) technology. Compared to other methods (hot or cold cathodes, capacitive pressure sensors), Spinning Rotor Gauges are highly accurate, long-term stable and do not influence the pressure signal that is measured in any way (no temperature input / ionization / gettering / drifts etc.).   The simple geometry and a stainless steel rotating ball that moves smoothly via electromagnetic forces is ideal for high-purity processes with various gases. Spinning Rotor Gauges (SRGs) were previously considered complex to operate and were therefore used almost exclusively in calibration laboratories.

Key features

  • First Autonomous working Spinning Rotor Gauge
  • Replacement for drifting/failing ION gauges
  • All metal/stainless steel/no energy transfer into vacuum/process
  • 10 mbar to 5 x 10-7 mbar measuring range
