This work is on a pyrometer. Pyrometer is a type of remote-sensing thermometer used to measure the temperature of a surface. in the modern usage, it is a device that from a distance determines the temperature of a surface from the spectrum of the thermal radiation it emits. A modern pyrometer has an optical system and a detector. The optical system focuses the thermal radiation onto the detector.
CHAPTER ONE
1.1 INTRODUCTION
You can feel a fire some distance away because it gives off heat radiation in all directions. In theory, if the fire behaves exactly according to the laws of physics, the radiation it produces is related to its temperature in a very predictable way. So if you can measure the wavelength of the radiation, you can precisely measure the temperature even if you're standing some way off. That's the theory behind a pyrometer: a very accurate kind of thermometer that measures something's temperature from the heat radiation it gives out at a safe distance (in some pyrometers) of up to 30m (100ft).
Pyrometer is a device that is used for the temperature measurement of an object. The device actually tracks and measures the amount of heat that is radiated from an object. The thermal heat radiates from the object to the optical system present inside the pyrometer. The optical system makes the thermal radiation into a better focus and passes it to the detector. The output of the detector will be related to the input thermal radiation. The biggest advantage of this device is that, unlike a Resistance Temperature Detector (RTD) and Thermocouple, there is no direct contact between the pyrometer and the object whose temperature is to be found out.
There are two basic kinds of pyrometers: optical pyrometers, where you look at a heat source through a mini-telescope and make a manual measurement, and electronic, digital pyrometers that measure completely automatically. Some devices described as pyrometers actually have to be touching the hot object they're measuring. Strictly speaking, instruments like this are really just high-temperature thermometers based on thermocouples. Since they don't measure temperature at a distance, they're not really pyrometers at all.
1.2 OBJECTIVE OF THE PROJECT
The objective of this work is to design a remote-sensing thermometer used to measure the temperature of a surface. From a distance determines the temperature of a surface from the spectrum of the thermal radiation it emits.
1.3 SIGNIFICANCE OF THE PROJECT
- Simple assembling of the device enables easy use of it.
- Provides a very high accuracy with +/-5 degree Celsius.
- There is no need of any direct body contact between the optical pyrometer and the object. Thus, it can be used in a wide variety of applications.
- As long as the size of the object, whose temperature is to measured fits with the size of the optical pyrometer, the distance between both of them is not at all a problem. Thus, the device can be used for remote sensing.
- This device can not only be used to measure the temperature, but can also be used to see the heat produced by the object/source. Thus, optical pyrometers can be used to measure and view wavelengths less than or equal to 0.65 microns. But, a Radiation Pyrometer can be used for high heat applications and can measure wavelengths between 0.70 microns to 20 microns.
1.4 LIMITATION OF THE PROJECT
- As the measurement is based on the light intensity, the device can be used only in applications with a minimum temperature of 700 degree Celsius.
- The device is not useful for obtaining continuous values of temperatures at small intervals.
1.5 APPLICATIONS OF THE PROJECT
- Used to measure temperatures of liquid metals or highly heated materials.
- Can be used to measure furnace temperatures.
