For the on-line measurement of solid and liquid particles in the form of aerosol. Additionally for the measurement of parameters of air, so as the speed, the temperature and the humidity.
The instrument can be applied to measuring of the particles’ grain-size distribution and concentration of aerosol in airflows. The measurement can take place vertically or horizontally.
The measurement method of the IPS analyser is complex rely on reflecting the influence of laser diffraction on measurement for the smallest particles in order to go on, for larger particles, in a continuous and gradual manner, to measure changes in the radiation stream scattered by moving particles. In this way, certain disadvantages of the “laser diffraction” used in the entire measuring range in which individual, largest particles yield weak changes in the diffraction pattern have been eliminated.
There are no optical limitations for measuring individual, small and large particles in the IPS analysers.
The laser radiation stream in infrared not only identifies size of particles, but also renders counting them precisely in the entire measuring range possible
An electric impulse corresponds to each participle. The impulse is proportional to the particle size. The set of particles is initially measured with the division into 4096 channels and converted (calibrated) into 256 size classes, which are available to a user..
During the measurement the flow and temperature of the air is also measured. At the end of measurement amount, surface and volume of particles is recalculated to quantities in 1 m3 of the air.
A general view on the IPS T analyser.
IPS T analyser consist in measuring probe [1] connected by cable [2] (20 m) to IPS electronic control unit [3] (ECU). The ECU is controlled by notebook [4]] by the USB 2.0. cable. The ECU [3] and notebook [4] are supplied by 230 V alternating current. As an option there is possibility to supply the analyser by 27 V direct current through current converter.
There is a particles’ sensor[7] with the intake tube[6] in the measuring probe [1]. The compressor[9] suck the air through the sensor[7].
The diagram of measuring probe of IPS T analyser
Above the body of the probe, on three tubes, there is Venturi tube[5] together with sensors to the measurement of the humidity and the air temperature. Indispensable pressure sensors and preamplifiers are in a body of the probe. The casing of the probe is made of 2 mm thick stainless steel.
On the basis of the measurement of the speed by Venturi tube[5], the ECU [3] assures isokinetic intake of aerosol into the intake tube[6] thanks to regulating of compressor expenditure.
In the case of sucking of aerosol from the motionless atmosphere, isokinetic intake is assured by a special cap. Application of the Venturi tube[5] above the intake tube[6] to the measuring sensor provides multiple deconcentration distraction of aerosol, tidying its flow up and the insensitivity to side breezes. The intake tube is treated as a diaphragm for determining the speed of the flow and the expense of aerosol by the measuring sensor.Besides the device can determine basic properties distribution of the set of particles, such as the surface or the volume, which at the identical specific gravity is equal to mass distribution. This distribution depends on the way of the calibration of the analyser.
