INFRARED THERMOMETER
HELLO FRIENDS,
TODAY I'LL TELL YOU ABOUT THE INFRARED THERMOMETER. NOW-A-DAYS IT HAS BECOME A VERY POPULAR DEVICE FOR CHECKING THE TEMPRATURES OF THE PEOPLE WITHOUT ANY PHYSICAL CONTACT.
SO, LET'S SEE , HOW IT WORKS??!
WE WILL DIVIDE THIS TOPIC INTO TWO CATEGORIES-:
1.) USE.
2.) WORKING.
3.) ADVANTAGES.
SO, LETS START-:
1.) USE-: HANDHELD INFRARED THERMOMETERS ARE WIDELY USED TO DETERMINE SURFACE TEMPERATURES AT MANY INDUSTRIES AND WORK PLACE.
ELEVATED TEMPERATURES ARE FIRST SIGN OF TROUBLE FOR ELECTRICAL CIRCUITS, MECHANICAL EQUIPMENTS AND BUILDING SYSTEMS.
2.)WORKING-: WE WIL ALSO DIVIDE ITS WORKING INTO 6 LEVELS...
a.))INFRARED RADIATION-: IT IS JUST ONE TYPE OF RADIATION THAT IS WITHIN THE ELECTROMAGNETIC SPECTRUM.
THE ILLUSTRATION BELOW SHOWS WAVELENGTH AND FREQUENCY OF THE ELECTROMAGNETIC SPECTRUM.IR IS LITERALLY HEAT , WE CANT DETECT IRBY OUR EYES BUT WE CAN FEEL IT.
WRAP YOUR HAND AROUND A CUP OF COFFE , SURELY YOU'LL FEEL A SIZZILING HEAT .....WHICH MAKES YOU DIRECTLY EXPERIENCE IR AND INTERACT WITH IR DIRECTLY BY THE ENVIRONMENT.
b.))HOW IR IS USED TO DETERMINE TEMPERATURE-: ALL MATTER EMITS HEAT IN THE ENVIRONMENT AND THERE IS A TEMPERATURE DIFFERENCE ESTABLISHED BETWEEN THE OBJECT AND THE SURROUNDING ENVIRONMENT , THEN THIS GRADIENT CAN BE MEASURED AND USED.
IF THE OBJECT IS AT SAME TEMPERATURE AS THAT OF THE SURROUNDING THEN THE NET RADIATION EXCHANGE WILL BE ZERO.
HANDHELS IR THERMOMETERS TAKE ADVANTAGE OF THIS "RADIATION DEPENDENCE" ON TEMPERATURE TO PRODUCE A VALUE FOR THE TARGETED OBJECT AND TO DISPLAY THE RESULT FOR THE OPERATOR TO READ.
IR WORKS LIKE A VISIBLE LIGHT- IT CAN REFLECT, FOCUSED OR ABSORBED. HANDHELD IR TYPICALLY USES A LENS TO FOCUS LIGHT FROM ONE OBJECT ONTO A DETECTOR , CALLED A THERMOPHILE.
THE THERMOPHILE ABSORBS IR RADIATIONS AND TURNS IT INTO HEAT. THE MORE IR ENERGY ,THE MORE HOTTER IS THE THERMOPHILE. THEN THIS HEAT ENERGY IS CONVERTED INTO ELECTRICITY.
THIS ELECTRICITY IS SENT TO THE DETECTOR WHICH USES IT TO DETERMINE THE TEMPERATURE OF WHEREVER THE THERMOMETER IS POINTING AT. THE MOR ELECTRICITY IS , THE HOTTER IS THE OBJECT. THE HIGHER TEMPERATURE, THE MORE ELECTRICITY IS SENT TO THE DETECTOR , THE HIGHER THE READING.
3.)ADVANTAGES-: THEY ARE FAST , ACCURATE , CONVINIENT TO HANDLE.
THE NON CONTACT FEATURE ALLOWS JUST CHECKING THE TEMPERATURE WITHOUT TOUCHING THE PRODUCT BEING TESTED. THIS LIMITS POTENTIAL PRODUCT CONTAMINATION.
SO, WE HOPE THAT YOU MUST HAVE LIKED THIS WORKING......SO KEEP READING US.
