Infrared Temperature Sensors

Infrared (IR) temperature sensors, also known as IR sensors or Infrared Sensors, emit an infrared energy beam focused by a lens onto a surface to detect the surface or object temperature. The reflected beam is received back in the sensor, which converts the energy to an electrical signal that can be displayed in units of temperature. The sensor compensates for ambient temperature variation to give an accurate temperature reading. They are a key component of thermal imaging cameras, are vital in energy conservation & maintenance and are also used in medical applications such as IR thermometers.

Measuring Different Surface Materials

With different temperature ranges, sensor types and outputs available, it is important to select the correct infrared temperature sensor for your application. When choosing an infrared temperature sensor, consider the type of material you need to measure. Materials like painted surfaces, paper, thick plastics, food, water, asphalt, rubber, wood, and other non-metals have high emissivity and can be measured easily with general-purpose sensors that have a fixed emissivity setting. For partially reflective materials, such as metals, use sensors with an adjustable emissivity setting to fine-tune the measurement accuracy.
