Optical Pyrometer

Introduction to optical pyrometer:

Pyrometry is a process in which the thermal radiation of any object is measured. The device which is used for the process of Pyrometry is called optical pyrometer. Incandescence color is that which is bright to human eye. The optical pyrometer is used to measure the temperature at the surface of a body. A pyrometer consists of an detector and an optical system. The latter focuses the heat radiations on the former. The output given by the detector is used to infer the temperature of the object. In real, there is no need for actual contact between the object and the pyrometer, because of the use of thermocouple and Resistance temperature detector. A instrument called ammeter is used to display the temperature of  the object, whose temperature is to be measured. However, Pyrometer is used for measuring the temperature of the applications from 500C to 1600C. Sometimes there is need to measure the temperature beyond the range of the thermocouples , which depends upon the energy being radiated from the object, under consideration. For this, optical pyrometers are used.It is quite clear from the discussion that pyrometer is used to detector the temperature of those objects, where actual contact is very difficult or hard to reach places on the objects.

How to Use Optical Pyrometer?

The optical pyrometer is very easy to handle and use. The user has to rotate the wedge ring on the optical pyrometer, to view the target object. A color blend is made between the wedge and the calibrated lamp of the instrument. The temperature can easily be measured by looking at the housing of the optical instrument.

Uses of Optical Pyrometer

In the metallurgical processes, it is necessary to control the temperature of the operations. A good metal can only be extracted only if there is regular check on the temperature inside the blast furnace. Moreover, effective control of the operations like, smelting can be easily done with the used of pyrometer. There are number of advantages associated with the use of pyrometer as it minimizes the consumption of the used fuel, good quality metal can be extracted too. It is also used in the Salt –bath furnaces for maintaining a steady range of temperature. The temperature of the steam in the super heater can be measured by using the optical pyrometer.
