5 Technical Description
5 Technical Description
5.1 System Design / Principle of Operation
Figure 1 shows the basic structure of the pyrometer with fibre cable. The infrared radiation coming from the
object is collected and focused by an fibre optic, that main parts are a lens and a aperture. Via a fibre optic the
infrared radiation is tranmitted to the pyrometer.
The basic parts of a pyrometer are the lens, aperture, filter detector, and the signal processing unit. The
infrared radiation coming in from the fibre optic is gathered by the lens. The aperture blocks unwanted rays at
the edges.
The filter permits only the desired spectral range to enter. The rays then pass through to the detector which
transforms the infrared radiation into electric signals. These signals are then linearised in the signal processing
unit and changed into a standard output signal which can then be read in the display, and be used for process
control.
The operating elements are located at the front of the panel instrument case, the connections / interfaces are
located at the back (see Operating and display elements (section 5.3) at page 9).
Figure 1: Structure of the pyrometer
5.2 Fibre Optics
The pyrometer is equipped with fibre optics and depending on the application (measuring distance, measuring
field diameter, etc.) the pyrometer can be used with a vario optic head or a fixed optical head.
5.2.1 Vario optis
The Vario optic can be adjusted to the required measuring distance and allows small measuring fields for
various distances to the object being measured. The object being measured can be at an arbitrary distance,
but must be at least as large as the measuring field at that distance (see Setting the optic (section 7.1) at page
13).
Figure 2: Fibre optic - optical head (vario optics)
8 KLEIBER 217 R - LWL

5 Technical Description
5.2.2 Fixed optics
The fixed optics is a fixed optics for very small measuring fields, i.e. a certain measuring field diameter is given
for a certain measuring distance.
Figure 3: Fibre optic - optical head (fixed optics)
IMPORTANT:
The fixed optic cannot be adjusted. The distances mentioned must be respected absolutely in order to
ensure the small measuring field.
5.3 Operating and display elements
The controls and the controller are located on the front side of the panel instrument case. For the meaning of
individual elements refer to legend Figure 4 and Figure 5, for operation of the pyrometer see Operation of the
pyrometer (section 7) at page 13.

6.1 Installation Site Requirements
CAUTION:
Measurement errors and damage to the pyrometer through:
∙ambient temperatures too high
∙strong contamination of the optics due to dust, smoke, steam or other causes like air pollution
∙electromagnetic interference sources
You must take into account the following climatic conditions and the requirements of the place of use
of the pyrometer!
6.1.1 Climatic conditions
The following requirements must be fulfilled with respect to the climatic conditions at the place of use of the
pyrometer:
∙temperature range 0 ∘C bis +40 ∘C (0 ∘C bis +260 ∘C for optical head and fibre cable)
∙maximum air humidity 60 % room temperature
∙atmosphere free of dust, corrosive vapors, and fume gases
6.1.2 Requirements at the place of use

6 Starting Up
6.2 Installation
6.2.1 Fix and connect the pyrometer
DANGER:
There is danger of injury and possible equipment damage by connection of cables under power!
Never connect cables under power! Make sure that the power supply is switched off before connection
of the cables to the pyrometer!
Install the pyrometer as follows:
1. The selected controller at the ordering is already correctly build in and adjusted.
2. Double check stable set up of the panel instrument case.
3. Double check stable set up of the fibre optic.
4. Connect the fibre optic with the optical head and with the panel instrument case. (Pay attention to the
color bend radius)
5. Connect the connecting cable according to the cable assignment with the used devices.
6. Connect the power cable.
XThe pyrometer is ready for use and the power supply can be switched on.
6.2.2 Align pyrometer
The pyrometer is equipped with an LED pilot light for accurate alignment of the sensor with the object to be
measured. Align the pyrometer with the object to be measured as follows:
1. Switch on the supply voltage to the pyrometer.
2. Allow a starting time of approx. 5 minutes for thermo-stabilization. Than the pyrometer has stabilized and
is ready to work with the given accuracy.
3. The pilot light is always on. Make sure that there is nothing in the path of rays.
Note:
In order to avoid measuring errors, the area of the pilot light must not be larger than the object to be
measured.
4. If you have a pyrometer with vario optic head, adjust the necessary measuring distance (see Setting the
optic (section 7.1) at page 13).
Note:
The fixed optics cannot be adjusted.
XThe pyrometer is thus aligned and ready for the temperature measurement.

7.1 Setting the optic
Please make sure which optic your pyrometer works with. The fixed optic has to be installed at the given
measuring distance to ensure the small measuring field. For the vario optic please adjust the necessary
measuring distance as follows:
1. Loosen the ring nut by turning it in a counter-clockwise direction.
2. Move the vario optic forwards and/or backwards, in order to adjust the pyrometer to the required measur-
ing distance. Mentioned distances in the data sheet are essential to be maintained.
3. After adjusting the measuring distance, lock the annular nut by turning it in a clockwise direction.
XThe optical head is thus adjusted to the required measuring distance.

7.2 Adjusting the emissivity
The emissivity is the relationship between infrared energy radiated from an object and the radiation energy of
a perfect emitter (black emitter) at the same temperature and the same spectral range.
The emissivity is material-dependent and of a considerable size in order to be able to determine the temper-
ature of an object accurately without contact. The emissivity of the object being measured must therefore be
known and be adjusted at the pyrometer.
Typical emissivities for various materials are available on our homepage at www.kleiberinfrared.com or in rele-
vant literature.
The instrument is calibrated at black body radiation (𝜀= 1,00). Real objects have an emissivity less than 𝜀=
1.00. This difference can be adjusted with changing the emissivity value from the pyrometer.

7 Operation of the pyrometer
How to find out correct emissivity:
1. First measure the real temperature of measuring object with a contact thermometer e.g. thermocouple or
resistance probes. The “black” temperature (spectral temperature) measured with a pyrometer adjusted
to emissivity = 1.0 usually gives a measuring value differing to real temperature because of the real
emissivity of < 1.0. The value given by the instrument usually will be less than the real temperature. The
emission ratio of most materials depends on temperature as well as wave length being measured.
2. You can get a correlation of the temperature scales, if you adjust the pyrometer at the exact temperature
with the help of the emissivity value.
XAfter adjusting the emissivity factor through a correlation measurement you can now measure
temperatures for the calibrated temperature range at an accuracy mentioned in the technical data.
IMPORTANT:
Please pay attention if you take over table values of emissivity to give the value of emissivity factor at a
certain wave length. Adjusting emissivity following table values is not as exactly as adjusting following
a comparing measurement.
Changing emissivity
The emissivity can be adjuested at the front side of the panel instrument case with the helf of the emissivity
potentiometer stepless between 0.1 and 1.
7.3 Adjusting the response time
The response time is the time interval in which the measuring temperature must line up with a precipitous
change at least in the measuring field, in order that the output value of the pyrometer reaches a given measured
value.
If the potentiometer for response time is set to “0” the pyrometer works at its standard response time of 180 𝜇s.
Other response times up to 2 s can be set in order to level out temperature drifts in a given time by averaging.

DANGER:
There is a danger of injury and possible equipment damage through in correct power supply!
Let problems relating to an incorrect power supply be eliminated by an electrical specialist! Do not
carry out arbitrary work on the electrical components of the pyrometer!
Only eliminate such problems yourself when their causes obviously relate to incorrect power supply, under-
cooling or contamination of the lens.
Do not undertake any interventions into the pyrometer. If problems arise which do not relate to the causes men-
tioned above, inform the service staff of the KLEIBER Infrared GmbH. (for contact data see Service address

9 Transport and Storage
9 Transport and Storage
9.1 Transport of the pyrometer
CAUTION:
Environmental factors, impacts and the formation of water condensation may damage some compo-
nents!
When transporting the pyrometer, take suitable measures to protect all components from environmen-
tal factors, impacts and the formation of water condensation! Temporary storage of the pyrometer in
the open air is not permitted!
Look at Taking out of service (section 11.1) at page 18 how to dismantle the pyrometer.
It is advisable to use the original packaging for the shipping of the pyrometer. If the original packaging is no
longer available, the pyrometer should be shipped in a cardboard box with shock-absorbing PE material.
When transporting the pyrometer observe the following instructions:
∙Take great care when transporting the pyrometer to avoid damage through the effect of force, or careless
loading or unloading.
∙Avoid jerks, vibrations and the formation of condensed water due to severe temperature deviations while
transporting.
∙In the case of overseas shipping, a suitable desiccator (e.g. silica gel) should be inserted and the pyrom-
eter should be sealed together with the desiccator in a protective plastic sheet.
∙If the pyrometer is not immediately installed after delivery and put into operation, then it should be carefully
stored in a location protected against dust and humidity (Storage of the pyrometer (section 9.2) at page
16).
XThe pyrometer is thus ready to be shipped.
9.2 Storage of the pyrometer
CAUTION:
Environmental factors, impacts and the formation of water condensation may damage some compo-
nents!
Store the pyrometer only in dry areas without large variations in temperature! The atmosphere should
be free of dust and corrosive vapors!
Store the pyrometer appropriately in the original packaging. Put a suitable desiccant inside the packing (e.g.
silica-gel) to prevent damage by moisture. Protect the pyrometer against dust through suitable measures.
The following climatic conditions are required in the storage room of the pyrometer:
∙temperature range -20 ∘C to +70 ∘C
∙maximum air humidity to 70 %
∙atmosphere free of dust and corrosive vapors
