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.
