Infrared thermometer
An infrared thermometer is also known as a pyrometer. From a physical point of view, there is no difference between the two terms. It is a measuring device that detects the infrared radiation of a measuring object and determines the temperature from this.
The infrared radiation is measured without contact from a certain distance and at a defined measuring point. The measuring distance and the size of the measuring field are determined by the lenses installed in the device. The term infrared thermometer is commonly used for low-cost mobile devices. The devices have a fixed lens and are optimized for a specific measuring distance. In contrast, the term pyrometer is used for devices that are used in industrial production. Pyrometers are often made up of adjustable and more complex optical lens systems. For precise measurement, the measuring distance can be adjusted exactly to the local conditions. Pyrometers are available with different lenses. Depending on the size of the measuring object or the required measuring distance, the optimum device solution can be selected for the application.
Infrared thermometers tend to be designed for short measuring distances and larger measuring objects.
In contrast, pyrometers are offered for very small measuring distances and measuring objects in the millimetre range as well as for measuring distances of several metres due to the wide range of optical solution variants. Particularly in the area of high-temperature applications with over 500 °C, the devices can be mounted at large and safe distances.
Stationary pyrometers have analogue and increasingly digital interfaces so that they can be connected directly to control systems and networks via bus systems.
Pyrometers are also primarily used in the field of research and development, as they are more versatile and flexible due to their optical capabilities. In addition, high-quality pyrometers have advanced functions for analyzing the measured values.
