SAFETY INSTRUCTIONS
General
Please read carefully the instructions given in TECHNICAL SPECIFICATIONS, espe-
cially the connection and operating instructions as well as the connection instructions
and configurations dealt with in SYSTEM START-UP.
The Infrared Radiation Pyrometer is an optical measuring instrument.
Dirty lenses will lead to measuring errors.
Please pay attention to the instruction given in MAINTENANCE AND CALIBRATION.
HEITRONICS production meets the latest technical development thereby applying so-
phisticated components. Nevertheless, functional errors may occur in exceptional
cases. The failure of an instrument may cause a measuring value being issued which
seems to be correct, but is wrong. Please pay attention to the instructions given in
MAINTENANCE AND CALIBRATION.
Only when using a female connector with cable or a dummy plug attached to the plug
of the device - in addition to the equipment sealing -, the specified system of protection
can be achieved.
Operation with laser
Devices completely mounted and equipped with integrated laser meet the safety
requirements of Laser class 2.
Before handling the lens in any way, the voltage supply is to be switched off or the
connecting plug is to be pulled out to ensure that the laser will not switch on automati-
cally.
The integrated laser can not operate up to the upper limit of the ambient temperature of
60 °C.
ATTENTION
In case of wrong connection,
the device might be destroyed.
ATTENTION
The Laser must not be switched on, if the lens
of the radiation pyrometer is removed.
ATTENTION
The Laser will be switched off at ≥40 °C
to defend it from destruction.

2.1 Measuring temperatures using Infrared Radiation Pyrometers
Above a temperature of absolute zero, which is approx. - 273 °C or 0 K, all bodies
emit electromagnetic radiation, the wavelength and density of which depend on the
temperature. Up to a temperature of approx. 600 °C, the wavelength of the radiation
can be found exclusively within the infrared range (thermal radiation). It is only at
higher temperatures where part of this radiation is emitted in the form of visible light.
The radiation emitted by the body (radiation density) also depends on the surface of
the individual body. At a fixed temperature, the maximum radiation density is emitted
by a "blackbody" source of radiation. All real bodies only emit a fraction of this radia-
tion density at the same temperature. The ratio of this fractional part to the maximum
radiation density is called the emissivity ε. Naturally, the emissivity is always < 1. It
depends on the nature of the surface of the material, on the material itself and on the
wavelength. If the emissivity is known, the temperature of the object can be deter-
mined by measuring the infrared radiation emitted by the very object.
Devices used to measure this kind of radiation are called Infrared Radiation Pyro-
meters.
As the measurement is effected without the Infrared Radiation Pyrometer being in
contact with the object, no distortion of the temperature field due to heat dissipation
need to be feared, as is the case, e.g., with probe-type thermometers.
The Infrared Radiation Pyrometer is a measuring transducer, which receives the in-
frared radiation emitted by the measuring object itself and transforms it into a stan-
dardized output signal.
All optic and electronic components are located in a small housing of a solid con-
struction, which is made from die-cast metal so that the installation of a radiation py-
rometer is possible even in narrow spaces.
By selecting a number of various lenses and detectors, it is possible to generously
modify the measuring field, if the measuring distance is given.
For the application of the Infrared Radiation Pyrometer under high ambient tem-
perature, water-cooling, air purge fittings and vacuum tight lenses can be delivered
as accessories.

2.2 Infrared Radiation Pyrometers for GENERAL APPLICATION
The Infrared Radiation Pyrometers series KT15.81 II / KT15.82 II /KT15.83 II are
used to measure surface temperatures within a temperature range of - 50 °C to
1000 °C. The spectral sensitivity can be found within the range of the atmospheric
window, which is between 8 and 14 µm. As the atmospheric transmissivity is very
high in this spectral range, no weakening of the infrared radiation due to CO2or to
water vapor contained in the air is to be expected.
To meet especially high requirements as to the transmission of the atmosphere as it
is a case e.g. when carrying out meteorological measurements radiation pyrometer
KT15.85 II is suitable.
The KT15.81 II / KT15.82 II / KT15.83 II can be employed in the measuring of tem-
peratures during the production and processing of plastics, rubber, paper, textiles,
paint, ceramics etc. The emissivity of various metals is shown in figure 10 (chapter 8:
Illustrations).
The devices can also be used to measure the temperature of objects exposed to in-
frared radiation, since the radiation maximum of infrared radiators is within the range
of shorter wavelengths, which do not cause the Infrared Radiation Pyrometers
KT15.81 II / KT15.82 II / KT15.83 II to react.
The Infrared Radiation Pyrometer KT15.81 II is used in the spectral range of 8 to
10 µm. Besides being used for large-surface measurement, this pyrometer type is
also suitable for measuring thick foils.
The Infrared Radiation Pyrometer KT15.82 II is applied for the standard measuring
range of 8 to 14 µm thereby guaranteeing a good signal resolution.
The radiation pyrometer KT15.83 II provides a particularly high signal resolution ow-
ing to its large spectral range. Therefore, it is very well suited for measuring low tem-
peratures.
For high requirements on the transmission of the atmosphere, such as found in me-
teorological measurements, the KT15.85 II type is available. This device type oper-
ates within the spectral ranges of 9.6 to 11.5 µm, where the transmission of the at-
mosphere is extremely high.

2.3. Infrared Radiation Pyrometers for measuring METALS
The spectral emissivity of the Infrared Radiation Pyrometers KT15.01 II / KT15.02 II
is 2 to 2.7 µm and 2 to 4.5 µm. Within this spectral range, metals and metal-oxides
show a relatively high spectral emissivity. This is why the device is particularly well
suited to measure the temperatures of these materials. Since the atmospheric trans-
missivity is high within the spectral range of 2 to 2.7 µm, distortions of the measured
value owing to absorption of water vapor and CO2in the air can be ignored
(Fig. 11, ILLUSTRATIONS).
The Infrared Radiation Pyrometer type KT15.01 II is used for measuring tempera-
tures from 300 °C onwards; the radiation pyrometer type KT15.02 II is suitable for
measuring temperatures from 200 °C onwards. Temperatures from 500 °C respec-
tively 700 °C onwards are preferably measured by means of the spectral pyrometers
of the series KT18S or the quotient pyrometers of the series KT18R.
2.4 Infrared Radiation Pyrometers for measuring PLASTICS
These types of pyrometers are employed for the measuring of surface temperatures
of plastics within a temperature range of 0 to 600 °C.
These Infrared Radiation Pyrometers are equipped with narrow-band infrared filters.
KT15.21 II measures radiation at 3.43 µm,
KT15.23 II measures radiation at 6.8 µm,
KT15.24 II measures radiation at 7.93 µm,
KT15.25 II measures radiation at 8.05 µm.
Within these spectral ranges, virtually all synthetic materials have strong absorption
bands so that even thin foils show high emissivity.
The Infrared Radiation Pyrometer KT15.21 II is suitable for most foils from 100 °C
onwards.
The Infrared Radiation Pyrometer KT15.23 II measures thin foils made from polyeth-
ylene, polypropylene, polyisobutane, polynitrile, polystyrene and similar materials
from 0 °C onwards.
The Infrared Radiation Pyrometer KT15.24 II and KT 19.25 II measure thin foils poly-
ester as well as foils made from
- acrylic,
- cellulose,
- fluorine compounds,
- polycarbonate,
- polyamide,
- polyurethane,
- polyvinylchloride
and similar materials after analysis from 0 °C onwards.

1/01/04e HEITRONICS Infrarot Messtechnik GmbH
2.5 Infrared Radiation Pyrometers for measuring GLASS
KT15.42 II is suitable for measuring glass and quartz. The spectral sensitivity is 4.9
to 5.5 µm. The emissivity of glass is very similar to the emissivity of a blackbody ra-
diator within this spectral range. Furthermore, this spectral range eliminates any dis-
turbing influences resulting from the strong absorption bands of water vapor at 6.2
µm.
The radiation pyrometers KT15.01 II and KT15.41 II are not measuring the surface
but the average value of temperatures up to a certain penetration depth (glass vol-
ume). The lower limits are 300 °C for KT15.01 II and 400 °C for KT15.41 II. The types
KT15.42 II and KT15.43 II measure the surface temperature from 100 °C respectively
from 0 °C onwards.
2.6 Infrared Radiation Pyrometers for measuring GASES
By means of narrow-band filters, the selective measurement of temperature of cer-
tain gases is possible. A rather long response time is to be chosen since the radiation
energy is very low.
KT15.21 II measures hydrocarbon from 100 °C onwards.
KT15.62 II measures materials within the absorption range of carbon dioxide and car-
bon monoxide,
KT15.63 II measures carbon monoxide selectively,
KT15.64 II is provided for nitrogen oxide and
KT15.69 II has been especially developed for determination of combustion tempera-
tures.
Using KT15.41 II, objects can be measured through gases and flames from 400 °C
onwards.

Technical Information
Cooling Jacket WK15
The HEITRONICS Infrared Radiation Pyrometers can be operated at an environmental
temperature of up to 60°C without any additional coolants. If the environmental tempera-
tures are higher than that mentioned above, cooling fittings can be used.
Basically, the cooling jacket WK15 can be cooled with air or water. The possible maximum
environmental temperatures are higher for water cooling than for air cooling (Æindividual
data sheet).
If the cooling process is too strong, i.e. if the cooling air / cooling water is too cold, this
may result in condensate as soon as cooling medium falls below the dew point. To pre-
vent this from occurring, the cooling air / cooling water must have a minimum temperature
as a function of the relative humidity.
The following table specifies the minimum temperature of the cooling air / cooling water as
a function of the environmental temperature and the relative humidity of the environmental
air.
