The use of pyrometers is always required when processes are to be monitored and optimized. Continuous temperature monitoring with pyrometers enables temperature deviations to be detected in order to produce a high-quality end product.
The material to be measured determines the pyrometer's spectral range, the listed areas of application lead to a pyrometer recommendation. Let us advise you for your application or for complicated measuring tasks.
Pyrometers for Laser Process Control and Temperature Control
Highspeed pyrometers with an integrated controller measure the temperature and thus control a given temperature level at the same time. The controlled laser power ensures a consistent quality of the processed material, even where changes of laser beam delivery would cause discontinuities in temperatures
A pyrometer in combination with a PID program controller REGULUS provides the fastest and most efficient method to rapidly detect temperature variations on inductively heated components and directly provides a 0-10 V manipulated variable for controlling the high-frequency generator.
Datasheet REGULUS RD / RF: PID program controller
Induction heating has established itself as a fast and efficient method for heating metallic or electrically conductive materials in industrial production. Modern induction systems quickly generate targeted workpiece temperature necessary for the process.
The necessary process temperature must be achieved as precisely and evenly as possible and hold for the required time to prevent material structures from being changed or even destroyed. The best solution for this is the fast non-contact temperature measurement with pyrometers as well as the control with specially developed temperature controllers.
With a combination of pyrometer and program temperature controller:
- Temperature changes on the inductively heated component can be detected very quickly and
- A continuously adjusted control variable for controlling the high-frequency generator is provided to the output
Functions of the programmable temperature controller REGULUS:
- Manual mode for easy ramps and hold times
- Program mode for direct approach to various setpoints, including ramp or time control
- Automatically determine useful control parameters
- Visually track, store, evaluate and document all processes via software
- Ability to make many more adjustments for every conceivable heating task
Our pyrometer recommendation:
SIRIUS SI23 is a 1-color pyrometer with temperature ranges from 50°C, 5 ms response time and spot sizes from 1.3 mm, laser targeting light as an alignment aid and a fixed focus optics with adjustable lens position to adjust the focus distance.
METIS M323, M318, M316 or M309 are 1-color pyrometers with temperature ranges from 50, 100, 200 or 550°C, 1 ms response time, very small spot sizes from 0.4 mm, with a focusable optics and laser targeting light, throug-lens view finder or camera module as an alignment aid.
Pouring Stream Monitoring
Intelligent pyrometers with pouring stream mode automatically detect the entire casting process and provide an average temperature of the complete cast. Disturbances such as hot slag spillings or drop at the beginning or end of the casting are automatically detected and eliminated from the final temperature. Thus, the cast monitoring ensures a consistent quality assessment of the end product.

Rolling Mills, Continuous Casting Plants,…
The heavy-duty measuring system in heavy stainless steel construction is designed for continuous temperature measurements in rolling mills, continuous casting plants and similarly harsh industrial conditions.
Application datasheet steel industry temperature monitoring with well protected flexible pyrometer measuring systems.
The optics system is designed for ambient temperatures up to 250°C, the purge air provides additional cooling and keeps the optics tube and thus the pyrometer’s sighting field free from contamination.
The electronics of the measuring system is mounted in up to 30 meters in a protected position.
Glass Gob Measurement
Short-wave infrared measurement devices are capable of detecting the glass temperature slightly below the surface. Thus, the measurement is not affected by a possibly cooled surface and is easy to evaluate. The measurement of the temperature distribution of glass gobs allows the optimization of heating processes.

Temperature Profile Measurement
High-speed pyrometers are able to create a detailed temperature profile from quickly passing parts. Using slower devices, detailed information is smoothed and does not allow an evaluation of important information. For example, it is thus possible to draw conclusions about different material thicknesses.

The non-contact temperature measurement of sooting flames in coal power plants, waste incinerators and other combustion furnaces is used to optimize the firing operation and the reduction of emissions in combustion chambers or to avoid slagging combustion chamber walls.

Spot Size Calculator
The spot size calculator is used to calculate the spot size diameter in front of and behind the focused measuring distance. To do this, the basic data must first be entered (see spot size table in the respective pyrometer operating manual), then the spot size can be calculated at a desired measuring distance.
