Range of Applications
Purpose
The FW 100 series from SICK AG is designed to conduct continuous measurements of very
low (0.1 mg/m3) to medium (200 mg/m3) dust concentrations – independent of the gas velocity, humidity, or charge of the particles involved.
Highlights
The probe design is particularly suitable for mounting on one side of the gas duct and does
not require any mechanical adjustment or calibration with a dust-free measurement path.
The measuring device can be used for a wide range of applications, including gas ducts with
extremely small or large diameters, as well as thick and thin-walled stacks.
Applications
‡ In pure gas, downstream of electrostatic precipitators
– Continuous measurement and monitoring of dust concentrations
– Protection of flue gas desulfurization plants at too high dust load
‡ In pure gas, downstream of modern fabric filters
– Monitoring, detection, and identification of defective filters and bags

■ Measurement value and event memory
The FW 100 transmitter/receiver unit can be equipped with a measurement value and
event memory as well as a realtime clock. With it the FW 100 can store up to 3000 measurement values, which are detected over a predefined period of time (e.g. half-hourly
values), and assign them a timestamp using the realtime clock. In addition, up to 100
events are stored in parallel. These include any changes in the operating status of the
device (maintenance, limit value violations, errors). The MEPA menu-driven parametrization program imports this data or displays it graphically.

1.3.5
Operation
Measuring Principle of the FW 100
The FW 100 operates according to the scattered light measurement principle (forward scattering). Since it is extremely sensitive, this principle is particularly suitable for measuring very
small particle concentrations.
Light source
Measuring volume
Detector
Fig. 1.3 Measuring principle
A laser diode directs a beam of modulated light (in the visible range) at the dust particles in
the gas flow. The light scattered by the particles is recorded by a highly sensitive detector.
The point of intersection between the transmitted beam and the receiver aperture defines
the measuring volume in the gas duct. The measured scattered light intensity is proportional
to the dust concentration. After a gravimetric comparison measurement, for example according to VDI 2066, therefore, a measurement signal that is directly proportional to the
dust concentration can be output.
Check Cycle (FW 101)
The check cycle lasts approx. 310 s and comprises a:
• contamination measurement on the optical boundary surfaces
• zero-point measurement
• check point measurement
The check value is recorded for approx. 40 s (last measurement value is maintained); the
check values are then output at the analog output.

Contamination
Measurement
(FW 101 only)
In order to measure the contamination on the optical boundary surfaces, the FW 101 moves
the receiver optics mechanically to a reference position. As a result, the optics measure the
light emitted by the laser diode directly. The measured intensity value is compared with the
factory or original settings to calculate a correction factor. In this way, the FW 101 can fully
compensate for any contamination levels.
Receiver optics in
reference position
Fig. 1.5 Contamination measurement (FW 101)

Check-Point
Measurement
(Span Test)
The FW 101 measures the check point by moving the receiver optics to the reference position. Once a reference measurement has been carried out with a light intensity of 100 %,
the FW 101 reduces the intensity of the laser diode to 70 % and compares the value measured by the receiver with the expected value. If these two values deviate from the upper
range limit by more than 2 %, the device generates an error signal.
Zero-Point
Measurement
In order to monitor the zero point, the FW 101 deactivates the laser diode. Since no light is
present in the duct, the reception signal must also be zero. In this way, drifts or zero-point
deviations in the entire system (e.g. caused by an electronic defect) can be reliably detected. If the “zero-value” deviation is outside the specified range, an error signal is generated.

Product Information
FW 100
Check cycle (FW 102)
The check cycle lasts approx. 200 s and comprises a:
• zero-point measurement
• check-point measurement
The check value is recorded for approx. 20 s (last measurement value is maintained) before
it is output on the analog output.
Check-Point
Measurement
(Span Test)
The FW 102 measures the check point with the reception optics in the measuring position.
The measurement lasts approx. 90 s. During this time, the light intensity changes between
70 and 100 %. Thanks to a large number of intensity shifts, which can be evaluated statistically, the FW 102 enables the check point to be measured with pinpoint accuracy. This also
applies with fluctuating dust concentrations in the gas duct. Deviations in the check point by
more than 2 % of the upper range limit are evaluated in the same way as with the FW 102.
Zero-Point
Measurement
Like the FW 101, the FW 102 carries out a zero-point measurement. The FW 102 also supplies extremely accurate measurement values without a contamination monitor, because
the purge-air flow has been optimized to take flow aspects into account. Contamination on
the optical boundary surfaces is only to be expected over longer periods of time. Furthermore, contamination on measurement devices using the scattered light principle has less
of an effect on the measurement signal than with other measurement principles.

Mounting the bracket for the purge-air unit
‡ Mount the brackets on the duct wall as shown in 2.3.1 Installation Proposal, see Fig. 2.1.
Mounting the FW 102 with 1” coupling or TRICLAMP®
The transmitter/receiver unit of the FW 102 can be mounted on the duct using a 1” coupling
or a flange for a quick-release lock (TRICLAMP®). In order to do so, first weld the 1” coupling
or flange for the quick-release lock to the duct.
Mounting the FW 102 with 1” Thread
ATTENTION
‡ Mark the mounting point of the coupling
‡ Cut a suitable opening the duct wall
‡ Weld on the flange or coupling
‡ Provide suitable reinforcements on thin-walled ducts or at mounting points that are subject to vibration.
Always weld the 1” coupling at an angle facing upwards of 1° so that any condensate can
drain off.
Note
A “11/2 : 1” reducing coupling can be used instead of a 1” coupling.

External purge-air unit (option)
‡ A separate disconnector – if possible, a motor circuit-breaker – must be installed in the
vicinity of the measuring devices
‡ A clear warning must be provided near the switch to prevent it from being deactivated
inadvertently.
‡ A phase-failure protection switch is recommended for three-phase.
The three-phase AC motor of the fan (type 2BH1300) is connected at 3 phase conductors
L1, L2, L3. The rated voltage of the motor in operating connection must match the phaseto-phase voltage of the network (operating voltage).
Motors with windings for 230 V (D)/400 V (Y) can be connected to the terminal board for
230 V or 400 V with direct starting and a suitable circuit.
