RPV-20 is an instrument designed for the detection and
measurement of the amount of dust present in an
environment. The measurement is performed between
the ends of an optical path.
RPV-20 is composed of 3 elements:
- TX -RX unit
- optical reflector
- power supply and electronic processing switchboard.
An infrared ray is emitted by the TX and directed towards
the reflector which reflects it towards the RX. The
distance between the optical unit and the reflector can
be chosen between 10 and 25m max.
The optical path therefore, being a reflection system, is
twice the distance between the optical unit and the
reflector.
For example, if the distance between the optical unit
and the reflector is 20m, the optical path is 40m.
The operating principle is based on the interaction
between the particles of dust present along the optical
path and the infrared ray emitted by the TX transmitter
and reflected and received by the RX.
The signal emitted by the RX is sent to the control panel
for signal analysis and processing.
The instrument reveals the difference in light intensity
between that emitted by the transmitter and that
detected by the receiver.
The more the amount of dust increases along the optical
path, the more the intensity of the light detected on the
RX unit decreases.
For a correct installation, we recommend reading and
scrupulously carrying out the instructions listed below.
The excellent operating results will largely compensate
for the time spent reading these instructions.

1.11.1
1.11.1
1.1 - during the unpacking and stationing of the
product, it is extremely important that the optical unit
of the RPV-20 (TX transmitter and RX receiver) is kept
away from very bright lights. In particular, it must be
absolutely avoided that the lenses of the optical drive
are hit by sunlight. The possible focus of sunlight on
sensitive internal photoelements can irreparably damage
the equipment
1.21.2

1.2 - avoid causing violent impacts to the optical unit
TX and RX which can be caused by accidental fall or
dynamic contact with other elements during installation.
Particular care must be taken during the fixing of the
TX-RX units and reflector on the walls to prevent them
from falling to the ground.
1.31.3
1.31.3
1.3 - during installation, care must also be taken in
protecting the front window of the optical drive. It is
necessary to avoid scratching, bumping, deforming and
dirtying this window, which has the double function of
mechanical protection and optical filter
1.4 - before installation it is very important to carry out a careful
and critical examination of the environmental conditions to
avoid absolutely that the installation could pose a danger to
people or things

3.13.1
3.13.1
3.1- Install the two optical elements, (TX +RX and
reflector or TX and RX) or their fixing brackets at an
height in accordance with the characteristics of the
environment and aligned with each other at a distance
chosen between 10 and 25 meters. The wall fixing of
the must be done carefully using suitable plugs.
It is extremely important that the detector fixing is well
done to avoid the danger of misalignment of the two
optical units that can cause a malfunction.
During this operation make sure that the two optical
units are sufficiently aligned with each other. The perfect
alignment will be carried out later during the optical
collimation phase.
3.23.2

3.2 - - The position of the reflector must be
perpendicular to the incident beam. Position shall be
chosen carefully considering the maximum angular
misalignment possible between transmitter / receiver
and the reflector(+/-1,5 degree)
3.33.3
3.33.3
3.3 - - A good method to install the reflector may be,
for example, a support with a good fixing

3.4 - Install the control panel in a favorable position for
operation with suitable wall plugs.
