ABSTRACT:
A method for measuring the characteristics of particles in a fluid by detecting electromagnetic radiation scattered on individual particles and an apparatus for performing the method are characterized in that the measurement takes place in structurally separated manner using at least one irradiating device and at least one receiver device in at least one sensor arrangement through which flows a fluid flow containing the particles to be measured, that in the at least one sensor arrangement signal formation takes place of a signal to be received in the receiver device using exclusively optomechanical elements and that signals are transmitted between the at least one sensor arrangement and the at least one irradiating device or the at least one receiver device by means of optical signal transmitters. This makes the apparatus particularly suitable for use in explosion-endangered environments and at difficultly accessible measurement locations, e.g. on chimneys.
