Application
Combined device for mensuration ratio and temperature in
rooms (e.g. workplace or conference rooms). Designed for lockup on management
and show systems. to boot, the device are often provided with a
passive temperature device e.g. PT100, PT1000,NTC10k etc.

Accuracy
Mounting Advices
The devices square measure provided in AN operational standing.
Installation is formed by suggests that of rawl plugs and screws (accessory) to
the smooth wall surface.
For wiring, the snapon
lid should be separated from the bottom plate.
Installation should be created on representative places for the space
temperature, to avoid a falsification of the mensuration result. Solar
radiation and draught ought to be avoided. If the device is mounted on
standard flush box, the tip of the installation tube within the flush box should
be sealed, therefore to avoid any draught within the tube falsification the mensuration
result.
Electrical association
Location and accuracy of roomsensors
The devices square measure created for the operation of protecting low voltage
(SELV). For the electrical association, the technical information of the
corresponding device square measure valid. Specially with respect to passive sensors
(e.g. PT100 etc.) in 2wire
conductor versions, the wire resistance of the
supply wire has got to be thought-about. Probably, identical has got to be
compensated by the subsequent natural philosophy. because of the selfheating,
the wire
current affects the accuracy of the measure. Thus, identical ought to
not exceed 1mA.
Besides an appropriate representative mounting place, reminiscent of the
room temperature, the accuracy of the temperature measure conjointly
depends directly on the temperature dynamics of the wall. it's necessary,
that the flush socket is totally closed at the wall aspect, so the
circulation of air could ensue through the gaps within the cowl. Otherwise,
deviations in temperature measure can occur because of uncontrolled air
circulation. what is more, the temperature device shouldn't be coated
by furnitures etc.. Besides this, a mounting place next to doors (occurring
draught) or windows (colder outsidewall) ought to beavoided.

power
The temperature dynamics of the wall influence themeasurement results of
the sensor. numerous wall varieties (brick, concrete, dividing and hollow
brickwork) have totally different behaviour with respect to thermal variations. A
solid concrete wall responds to thermal fluctuations inside an area in a very
much slower approach than a light-weight
structure wall. temperature
sensors put in in flush boxes, have a extended reaction time to thermal
variations. within the extreme case, they discover the bright heat of the wall
even if for instance the air temperature within the space is lower. The faster
the dynamics of thewall (temperature acceptance of the wall) or the longer
the selected inquiry interval of the temperature device, the smaller square measure the
deviations restricted in time.
Room temperature device with electronic parts continually have a
dissipated power, that affects the temperature measure of the
ambient air. The dissipation in active temperature sensors shows a linear
increase with rising in operation voltage. This dissipated power has got to be
considered once mensuration temperature. just in case of a set in operation
voltage, this can be ordinarily be done by adding or reducing a continuing offset
value. As Thermokon transducers work with a variable in operation voltage,
only one in operation voltage are often taken into thought, for reasons of
production engineering. Transducers 010V/
420mA
have a customary
setting at a in operation voltage of 24VDC. that's to mention, that at this voltage,
the expected mensuration error of the signaling are going to be the smallest amount. As for
other in operation voltages, the offset error are going to be inflated or lowered by a
changing power loss of the device natural philosophy. If a recablibration
should
become necessary later directly on the device, this will be done by suggests that
of a trimming potentiometer on the device board (for sensors with LONinterface,
arecalibration
can bedone via corresponding software package variable
SNVT). Remark: Occurred draft results in a higher carryingoff
of dissipated
power at the device.Thus, temporal restricted fluctuations would possibly occur
upon temperature measure.
For active space sensors with transmitter, that square measure equipped by AN
additional passive temperature device (NTC, PT100, PT1000...)on
customer's request, it's necessary to compensate the error of
measurement occuring by the dissipation of the natural philosophy within the downstreamed
controller by anoffsetvalue.
Application Notice
Due to air circulations dirt and mud particles are often cumulated within the
course of your time on the form filter that is protective the device.
Thus, the perform of the device are often affected. when having
dismantled the filter, identical are often cleansed by processing it out with oilfree
and filtered compressed gas, superclean
air or element or by
washing it out with H2O. If the filter is simply too dirty, the same
should get replaced.
Refrain from touching the sensitive wetness device. Any bit of the
same can end in AN expiration of the assurance.
When victimisation the device in aggressive gases, AN early recalibration or a
change of the wetness device will become essentially. Such a
recalibration or a probable device amendment don't return below the
general assurance.
