Application examples for non-contact temperature measurement

The process and product temperature is an important physical indicator for manufacturing processes and ensures a high quality level of the production line. 

All Optris products apply in different areas, covering the non-contact temperature measurement. This covers the plastic industry, the food industry as well as the solar industry and life science. 


The automotive industry covers many manufacturing steps in which different materials are processed.
The processes can be monitored and optimized by infrared thermometers and infrared cameras to ensure an efficient quality of the products.



Examples: Control of components within test stations; laminating of car interiors: error displays at vehicles


The production process of plastic products is as versatile as the plastics itself.
We will only name the most common processes as there are different demands regarding the temperature measurement.



Examples: thermoforming of foil; surface refinement at the embossing calendar; production of PET bottles


Different processes within the medical area can be monitored and optimized through the use of non-contact temperature measurement.
Our products are used by producers of medical products but also by health professionals for fast diagnosis.


Examples: Monitoring of cryogenics; production of glass shots; manufacturing of dental products

Solar cell

A continuous process control and optimization within the semiconductor industry is of great importance.
This can be carried out through the temperature steering via an infrared thermometer or the quality securing via infrared cameras.

: string brazing of solar modules; quality control of solar modules; test stations of conductor boards


Non-contact measuring sensors are an important part of metal production and processing.
Through the use of measurement devices, a high quality of products can be achieved as well as a reduction in the process costs through specific process optimization.


Examples: Inductive curing and striking; contraction process; measurement of casting temperature

Temperature measurement in glass industry


Especially the glass industry depends on temperature control due to its energy complex manufacturing steps.
By monitoring the temperature of the products and the equipment, highest quality can be assures to stand ones ground on the market. 

Examples: Monitoring of glass melting bowls; Production of container glass; manufacturing of flat glass

Temperature measurement in pulp / paper / textile industry

Pulp, Paper, Textile

Drying processes are an important part of the individual steps in production within this branch.
Temperature measurement devices should be installed at different stations to ensure a successful cycle.
Temperature monitoring is also important during further processing.

Examples: Textile drying; microwave drying of paper; imprinting of paper within offset machines

Temperature measurement for laser processes


During connection and cutting processes with lasers, a linear extension of the basic material needs to be accounted which is specific to the material and depending on the temperature.
The product temperatures close to the cutting and connecting area as well as the process can be rectified with the help of the small and fast IR temperature sensors of Optris.

Examples: Laser welding; laser cutting


The preventive maintenance is gaining more and more importance.
Whether the monitoring of electrical and mechanical facilities or within air conditioning, infrared thermometers and cameras can be of help to detect weak points or defects.
Expensive deadlocks can therefore be avoided.
