Infrared Temperature Sensors | IR Sensors | RS Components

Infrared (IR) temperature 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.

How to Choose and Use Infrared Thermometers - Grainger …

04/11/2020· Handheld IR thermometers use a lens to focus the infrared energy from an object onto a sensor that measures it, typically a thermopile. The sensor absorbs infrared radiation and converts it to an electrical signal, with more intense radiation creating a stronger signal. The IR thermometer processes this signal in order to deliver a temperature readout.

Are Infrared Thermometers Dangerous? (Doctor's Advice)

Infrared thermometers use infrared radiation emitted by bodies and objects to convert it into a screen temperature. First, emitted IR radiations from a human or body are absorbed by the lens and transferred to the thermometer’s thermopile or sensor. At the thermopile, the conversion of thermal energy into electrical energy takes place. The ...

Infrared Thermometer - an overview | ScienceDirect Topics

An infrared thermometer uses a lens system to focus radiation onto an infrared detector that converts the energy absorbed into an electrical signal. The temperature inferred from the electrical signal is corrected for the emissivity of the source. Using optical filters, infrared thermometers may employ a very narrow range of wavelengths, whereas other systems may use a very broad range of ...

IR Thermometers explained - FireCraft Safety

All objects give off heat in the form of infrared radiation (IR). IR thermometers measure the IR emitted by an object to determine the temperature of the object. They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns, to describe the device's ability to measure temperature from a distance.
