Infrared thermometers, or pyrometers, are non-contact infrared sensors capable of single-point temperature measurements. These IR sensors find utility across a wide array of applications owing to their varied laser technologies and filters. In many cases, infrared sensors are sufficient for controlling entire processes through point temperature measurements, offering an unbeatable price-to-performance ratio compared to IR cameras. Despite differing in optics, electronics, technology, size, and housing, these IR sensors share a common signal-processing chain. Their compact nature enables easy integration into diverse application environments.
Infrared (IR) Cameras for Thermography
While traditional cameras capture visible light, infrared cameras operate in higher wavelength regions to measure surface temperature based on detected radiation. These IR cameras capture images that can be translated into temperature images, often represented using false color schemes. Thermal imaging cameras excel in identifying areas of warmth or coldness, making them invaluable for various applications:
Analyzing dynamic thermal processes in product and process development.
Stationary applications for continuous observation and control of thermal processes.
Portable usage in maintenance for detecting thermal leaks, facilitated by user-friendly smartphone integration.
Stationary installations of USB infrared cameras offer galvanically separated process interfaces, enabling transmission of temperature information as 0/4-20 mA or 0-10 V signals. Additionally, these thermal imaging cameras support area-related emissivities and reference temperature measurements through voltage input, further enhancing their versatility.
