摘要:
An apparatus for detecting condensable components in a gas stream comprising a sensor cell. The sensor cell comprises a probe, means for cooling the probe, means for transmitting light to the probe surface in a pressurized chamber, means for receiving returned light scattered from the cooled probe surface and means for determining the presence of condensate from a reduction in scattered light intensity. The probe surface is provided in its centre with a depression of low angle.
