SAFETY INSTRUCTIONS

Please read carefully the instructions given in TECHNICAL SPECIFICATIONS, especially

the connection and operating instructions as well as the connection instructions and con-

figurations dealt with in SYSTEM START-UP.

ATTENTION

In case of wrong connection,

the device might be destroyed.

The Infrared Radiation Thermometer 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 sophis-

ticated 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 automatically.

ATTENTION

The Laser must not be switched on, if the lens

of the Infrared Radiation Thermometer is removed.

The integrated laser can only operate up to the upper limit of the ambient temperature

of the Infrared Radiation Thermometer (60 °C).

ATTENTION

The Laser will be switched off

at an ambient temperature ≥60 °C

to defend it from destruction.

2.1 Measuring temperatures using Infrared Radiation Thermometers

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 Ther-

mometers.

As the measurement is effected without the Infrared Radiation Thermometer 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 Thermometer is a measuring transducer, which receives the

infrared radiation emitted by the measuring object itself and transforms it into a

standardized 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 Infrared Ra-

diation Thermometer 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 Thermometer under high ambient tem-

perature, water-cooling, air purge fittings and vacuum tight lenses can be delivered

as accessories.

2.2 Infrared Radiation Thermometers for GENERAL APPLICATION

The Infrared Radiation Thermometers 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 Infrared Radiation

Thermometer 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 Thermometers

KT15.81 II / KT15.82 II / KT15.83 II to react.

The Infrared Radiation Thermometer KT15.81 II is used in the spectral range of 8 to

10 μm. Besides being used for large-surface measurement, this Infrared Radiation

Thermometer type is also suitable for measuring thick foils.

The Infrared Radiation Thermometer KT15.82 II is applied for the standard measur-

ing range of 8 to 14 µm thereby guaranteeing a good signal resolution.

The Infrared Radiation Thermometer KT15.83 II provides a particularly high signal

resolution owing to its large spectral range. Therefore, it is very well suited for meas-

uring low temperatures.

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 Thermometersfor measuring METALS

The spectral emissivity of the Infrared Radiation Thermometers 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 Thermometer type KT15.01 II is used for measuring tempera-

tures from 300 °C onwards; the Infrared Radiation Thermometer type KT15.02 II is

suitable for measuring temperatures from 200 °C onwards. Temperatures from 500

°C respectively 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 Thermometers for measuring PLASTICS

These types of Infrared Radiation Thermometers are employed for the measuring of

surface temperatures of plastics within a temperature range of 0 to 600 °C.

These Infrared Radiation Thermometers are equipped with narrow-band infrared fil-

ters.

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 Thermometer KT15.21 II is suitable for most foils from 100 °C

onwards.

The Infrared Radiation Thermometer KT15.23 II measures thin foils made from poly-

ethylene, polypropylene, polyisobutane, polynitrile, polystyrene and similar materials

from 0 °C onwards.

The Infrared Radiation Thermometer KT15.24 II and KT 19.25 II measure thin foils

polyester as well as foils made from

- acrylic,

- cellulose,

- fluorine compounds,

- polycarbonate,

- polyamide,

- polyurethane,

- polyvinylchloride

and similar materials after analysis from 0 °C onwards.
