What is an IR temperature sensor?
Infrared (IR) Temperature sensor is a device that senses IR radiation from a remote object and reports it back as a temperature. This device works optically by shooting IR radiation, changing radiation into electricity and displaying the temperature of this electricity. The IR spectrum is generally considered to be 0.7 and 1,000 microns, but the IR temperature sensor can only feel part of the entire zone. Most IR temperature devices are made to detect specific IR wavelengths, so the owners may need several devices at a time; Some models have adjustable sensors, but not much. Primarily, the temperature sensor is used to safely determine the surface temperature without having to be close to the material.
Most objects, when they emit any amount of heat, also emit radiation; This applies to everything except black - an object that only absorbs energy and radiation and does not release anything. The IR temperature sensor uses optical capture that detects the amount of IR radiation. This radiation is then converted into electricity, which device againconverted to a temperature that is displayed to the user.
IR is usually measured in microns and lies between 0.7 and 1,000 microns. Although it is a large spectrum, the IR temperature sensor responds only to 0.7 and 14 microns, which ignores most IR spectrum. This is because other parts of the spectrum are not responsible for emitting heat, which must be react to the rest of the spectrum.
Most IR sensor units are specialized to respond to a certain number of microns based on material. For example, glass emits about 5 IR microns of radiation; The use of a sensor that responds to a lower or higher number of microns would result in an inaccurate temperature evaluation. Some sensors are adjustable and can be set to difference microns, but they are unusual.
These temperature sensors are commonly used to ensure safety, as some surfaces may be dangerously hot. For exampleHot metal or glass cannot be measured directly without endangering someone. However, the IR temperature sensor can be used from a distance, so the user should be safe from the material while still getting accurate temperature assessment. Most IR temperature sensors are accurate and can be turned off by 1 ° or less of the actual temperature.
