Metal Production
In all industries, one of the most important
physical measurements is related to temperature. Temperature is a basic
requirement for the control of production processes.
We can support you in improving your production processes. IMPAC Infrared
GmbH has 50 years experience in non-contact temperature measurement,
exemplified by specific expertise in the application of pyrometers and
thermal imagers in various industries.
IMPAC Systems GmbH, a subsidiary company of IMPAC Infrared GmbH,
integrates and adapts customer specific systems to individual measuring
applications. Therefore, the measuring system can be easily integrated into
the customers facility – for example to control and monitor production
processes.

"BurrDetection" on steel slabs
When cutting steel slabs, there is a flow of slag which
solidifies as burr on the underside of the slab. The removal of this burr is
inevitable. The deburring system, however, may slip over the burrs which are
sometimes extremely flat.

Glass Production
The glass industry measures temperatures of
transparent and non-transparent objects. Special requirements of glass
temperature measurement have to be considered. The main differences are
related to the measurement of the glass surface temperature or core
temperature.
|
|
|
|
Glass melting furnaces, working end and feeder
Because of their advantages, pyrometers are replacing the
previously used thermocouples for the measurement of temperatures in
melting furnaces, forehearths, working ends and feeders. Specific
glass-pyrometers with fibre optics can be used at ambient temperatures up to
250°C without water cooling.
|
|
Glass gob temperature measurement
Glass gob temperature measurement is only possible
using non-contact thermometers. The pyrometers needed for this application
have to be fast due to the high cycle frequency and must be capable of
measuring the temperature inside the gob. This is needed because the surface
temperature of the glass is easily influenced by ambient conditions.

|
Glass mould temperature measurement
The measurement of glass mould temperatures
requires a very rapid operation because the moulds open and close at high
speed. A pyrometer with a short response time is necessary. Since it is a
measurement of a metallic surface, a pyrometer with a spectral response in
the short wavelength is mandatory.

|
Glass treating processes and bulb manufacturing
The surface temperature is a decisive parameter for
annealing and bending of flat glass, shaping of the glass with gas burners
or producing lamps . For this reason only a low depth of penetration is
needed.
|
|
Portable pyrometers in the glass industry
Many applications in the glass industry need the use of
portable pyrometers. The choice of the best suitable pyrometer depends on
the desired application.

Induction Hardening
In induction hardening processes the temperature of
the workpiece is one of the most important factors to guarantee the required
product quality. The non-contact temperature measurement offers numerous
possibilities in this field of application. Especially developed pyrometers
and customized solutions enable a non-contact temperature measurement on
workpieces for different applications and specifications.
|
|
|
|
Temperature measurement in induction hardening processes
The monitoring and the controlling of temperatures is one
of the most important factors to guarantee the required product quality and
profitability in induction hardening processes. For these applications
pyrometry allows a separate and accurate measurement and documentation of
each components temperature.
|
|
Progressive hardening
At progressive hardening processes the inductor moves
along the workpiece. To guarantee repeatable and comparable measuring
results fibre optics pyrometers should be used. Combined with the inductor
the optical head of these instruments can be moved along the workpiece.
|
|
Process optimisation using thermal imagers
For the optimisation of induction heating processes
(heating speed and generator power), thermographic systems have proven
reliable, because they are capable of measuring the complete workpiece
during the heating process.
|
|
|
|
Pouring Stream
To guarantee the tight quality specifications in
foundries, the control and the documentation of production parameters gain
importance. A special focus is put on the measurement of temperatures in
production processes. The special properties of the pouring stream as a
measuring object requires special knowledge and customized solutions.
|
|
|
|
Pouring Stream Measurement
In foundries non-contact temperature measurement
techniques are increasingly replacing the use of conventional thermocouples.
Specially designed pyrometers satify the specific requirements of the
measurement of pouring streams.

Aluminium Processing
In the aluminium industry temperatures of molten
aluminium or hot finished goods can be measured. The temperature of machine
parts used in the process can also be detected. IMPAC Infrared has developed
special pyrometers and solutions for the aluminium industry. These products
optimally meet the specific requirements and problems of non-contact
temperature measurement of aluminium.
|
|
|
|
Extrusion
The production process of aluminium extrusion profiles
can be controlled completely using non-contact temperature measurement. The
quality of the final product can be improved dramatically by temperature
control.
|
|
Melt, Pouring Stream
Pouring streams of aluminium can only be measured with
pyrometers using the optical non-contact technology.
|
|
Forging
The measuring conditions while forging aluminium provide
usable and easily repeatable results.
|
|
|
|
Rolling
Rolling aluminium is done at very different temperatures
- depending on the processing step. Different pyrometers can be used
depending on the temperature and the application area.

Portable Thermal Imagers
|
|
|
|
Building Diagnostics
For some years now, thermal imaging cameras have been
used successfully in the thermography of buildings. These cameras assist
architects and surveyors in different areas:
- Investigating the condition of buildings
- Detecting thermal bridges and leakages
- Preparing expert reports
|
|
Predictive Maintenance
Thermographic measurements using thermal imaging cameras
have been a well- established component in the maintenance of electrical and
mechanical systems as well in the check of industrial equipment:
- Locating thermal anomalies
- Detecting potential or existing deficiencies or defects
- Predictive management of maintenance tasks
