Thank you for pointing that out! We have updated the title :) Please forgive us. 😅

Glad you liked it!

Hi! This is our IoT Cloud Studio. movitherm.com/solutions/early-fire-detection/

You can get it from movitherm.com

Hi! There are cameras referred to as "streaming" thermal cameras. They have temperature calibrated, pixel by pixek values

Hi @fortuneasuoma7073! Thanks for pointing that out! Love the attention to detail. The '>' sign should be a '<'. We will make sure to fix that.

Hi! Not with that system. However, we have other NDT systems that can measure defect size and thickness.

The FLIR A300 is long obsolete. The A50 or A400 replaces it.

Thanks guys for pointing that out! We'll make sure to fix that!

The infrared radiation comes from the heat of the particles. Let's imagine a molecule vibrating (due to heat) in a dense sea of air molecules. When it vibrates, the surrounding molecules will follow up and down due to electromagnetism, like making a wave from lifting a heavy rope up and down. This wave it creates is called an electromagnetic wave, specifically with the infrared wavelength. In fact, if the particle is hot enough the EM wave may be of a visible light wavelength due to a phenomenon called blackbody radiation (but now I'm getting side tracked). When the heat of the particle emits an EM wave, an infrared camera can detect it using a thermocouple. A thermocouple is an electrical device who's power changes depending on its heat. This is how we can record the heat, but then also transmit it to a screen who's pixel color is adjusted based on the power of the thermocouple (which is given by the heat of the object the infrared camera is sensing).

Hi! This one is in the works! Stay tuned!

You bet!

Glad it was helpful!

that’s because air is made of fast moving gases. they dilute each other to make a homogeneous (evenly distributed) mixture, so the temperatures of air will remain relatively uniform all throughout. the infrared camera would detect differences in temperature, so if you had concentrated hot gas contained near colder gas then it would likely be shown on the camera. think: hot exhaust exiting a car

What @@franklinmontez8733 said! Thanks for the answer!

@movitherm Is this the physics explanation? I don't think any of 'franks' answer is true. Sounds like a childs guest. The camera will not measure air at any temperature, nor liquid nitrogen (which is 78 % of the air) Why not?

@@fractalnomics yes, that’s the physics answer. liquids and gases have higher entropy than solids, which favors mixing- heat will be transferred from gases and liquids faster than from a solid (the main reason temp irregularities are easier to see on solids). The temperature IS detected from gases and liquids, but think of it as the background. If for example the temp of the liquid reads green on the infrared camera, then all you’ll see is green (as the heat is spread evenly throughout) and you may go “Hey, it’s all one color. Why is it not detecting temperature!” but it is, and you just can’t see many irregularities.

@fractalnomics where did you go home boy? where is the next brain buster question?

There are different infrared camera detector technologies available. Each one works a bit different. We essentially differentiate two main categories, micro-bolometer type detectors and quantum well based detectors. The micro-bolometer type has tiny thermocouple elements as pixels that change resistance based on the infrared radiation it is exposed to. The quantum well type actually measures photons in the infrared wavebands. Either the change in resistance or the amount of photons captures is then digitized into a digital count. Some magic sauce is used to convert infrared radiation into temperature and on the software side you can now measure temperature.

@@movitherm bruh put this in the video with visuals so everyone can understand. Why give visuals for the simple part then boring paragraphs for the RELEVANT but complicated and boring part😑

Search "How do Camcorders work?" I have read the creator's reply and it seems to be that. I am a student and i am learning, if i made a mistake, kindly inform me and explain it to me.

Hi! Wow - that is a deep and interesting question! A black hole and a black body are two very different concepts in astrophysics and thermodynamics. Black Hole: A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. It is formed when a massive star collapses under its own gravity, creating a singularity, a point of infinite density at its core, surrounded by an event horizon beyond which nothing can return. Black holes are characterized by their mass, spin, and charge. They can vary in size from a few times the mass of the sun to millions or even billions of times the sun's mass. Black holes are not objects that emit radiation; they are defined by their ability to trap everything within their event horizon. They can, however, indirectly affect their surroundings by gravitationally influencing nearby matter and light. Black Body: A black body, in the context of thermodynamics and physics, is an idealized object that absorbs all incoming radiation and emits radiation according to Planck's radiation law. It is an ideal absorber and emitter of electromagnetic radiation. A black body does not have to be a physical object; it can also represent a theoretical concept. In practice, objects like a cavity with a small hole, such as an oven or a star, can closely approximate the behavior of a black body. The radiation emitted by a black body is characterized by its temperature, and the spectral distribution of this radiation follows Planck's law, which describes how the intensity of radiation varies with wavelength at a given temperature. In summary, a black hole is a massive, gravitationally collapsed object in space, while a black body is an idealized concept in thermodynamics that perfectly absorbs and emits radiation. They are fundamentally different in nature and have different roles in their respective fields of physics.

No way! That's pretty cool!

You’re welcome 😊
