Temperature Measurement


Pyrometers for industry

January 2021 Temperature Measurement

Pyrometers are temperature measurement instruments that operate on the principle of infrared radiation, i.e., they detect infrared radiation of objects to determine the temperature without making contact with the process or surface being measured. In many industry sectors, the use of non-contact temperature measurement instruments is essential. For example, it is used for controlling complete factory processes or measuring even the smallest components to ensure a consistent quality level. With its extensive Impac pyrometer product portfolio, developed from years of research and customer contact, Advanced Energy can provide solutions for almost every application request.

The portable Impac Series 8 pyrometers are suitable for measuring metals, ceramics, graphite, etc. Also, they can be used for special applications such as measuring pouring streams or for temperature monitoring in coke ovens. The focusable optics and compact design allow for easy operation and data capture during the measurement process.

These robust, classically designed, handheld infrared thermometers offer small spot sizes, maximum value storage, and temperature indicators.

From the flagship series of stationary pyrometers, the Impac ISR 6‐TI Advanced represents the first industrial grade infrared pyrometer with thermal imaging capabilities, i.e., a pyrometer and thermal imager in a single solution. It uses two-colour (ratio) technology to measure the centre spot’s temperature for ranges between 700°C and 1800°C. The built-in video camera’s infrared filter auto calibrates the thermal image. The video output is transferred to a PC via USB, and InfraWin software generates the image.

Another versatile infrared-measurement highlight is the Igar 6 Advanced, a pyrometer with Smart Mode functionality for industrial applications. It includes a unique switchover technology that transitions between modes, creating a wide temperature measurement range from 100-2000°C.

In Smart Mode, measurements in the range 100-250°C will be taken in 1-colour mode, whereas in the range between 280°C and 2000°C, measurements will be based on the 2-colour (or ratio) method. In the range from 250°C to 280°C, a continuous transition from 1-color to 2-color measurement automatically takes place.
