Optris GmbH

Optris – Non-contact temperature measurement made in Germany

Optris has been developing and manufacturing innovative infrared measurement devices for industrial temperature measurement, including infrared cameras, stationary industrial IR thermometers and handheld thermometers for area and point measurement, for more than 17 years.

Our comprehensive product portfolio comprises infrared measurement devices for different industrial applications as well as research & development. Along with our free thermal analysis software, our measurement devices enable constant monitoring and control of virtually every manufacturing process, and reductions in production costs through specific process optimization.

Temperature monitoring in the glass industry

Glass has been a mainstay of human life for centuries. Be it in the form of jewelry, the facades of buildings, or drinking containers, it comes in every size, shape and color imaginable. The most translucent material places very specific demands on non-contact temperature measuring technology.

As described in detail in our Infrared Basics brochure, reflection and transmittance are serious considerations. Depending on whether one is measuring the surface temperature of the glass, or the temperature within the glass itself, specific infrared thermometers or thermal imaging cameras are recommended by Optris.

Below you will find a number of areas of application and the respective product solution.

Process control during glass tempering

With the new glass inspection system, temperature differences during glass tempering processes can be quickly detected, avoiding rejects and providing automatic quality monitoring.

Recommended devices:
Infrared thermometer CT G5L and infrared camera PI 640i

Area measurement

Thermal imaging cameras are always used when temperature values within an area need to be monitored, for example in the manufacturing of sheet glass.

Recommended devices:
Thermal imager optris G7 series

Measurement of moving objects

Likewise, infrared cameras are used when measurement objects are in motion, for example in the industrial production of glass beads or in packaging and filling plants which have a high output. When the objects always move within an orbit and are only to be measured at individual points instead of across the entire area, an infrared thermometer with high measurement speeds can also be used.

Recommended device:
Thermal imager optris Xi 400 or Pyrometer optris CTfast LT

Measurement in confined spaces

In practice, there is often only a very restricted space available for sensors, for example when they are being integrated into machines or systems. For this job there is a specially developed compact series glass pyrometer available.

Recommended device:
Infrared thermometer optris CT G5

Measurement of very small objects

IR thermometers enable the measurement of the smallest objects from 1mm in size at a distance of 70 mm. Corresponding special developments for the glass industry enable the precise measurement of glass surfaces, for example in the manufacturing of laboratory glassware.

Recommended device:
Infrared thermometer CTlaser G5 or CSlaser G5HF

Measurement through glass

Pyrometers with a special measurement wavelength of 3.9 µm are suited for precise temperature measurement between 200 °C and 1,650 °C through flames and glass. Non-contact IR thermometers are used for the measurement of workpieces in ovens through flames, as well as for the continual temperature monitoring of brickwork in furnaces.

Recommended device:
Infrared thermometer CTlaser MT

Measurement in hot surroundings

For the harshest conditions in the high temperature field, an infrared thermometer has been developed that can operate without additional cooling at ambient temperatures of up to 250 °C. This can be used in ovens and in closed chambers.

Recommended device:
Infrared thermometer CThot LT
