Pyrometre
‘Pyro’ is the ‘Greek’ word which means
fire. Pyrometer is touch less type (controlled
type) temperature measuring device. Where
radiation energy of the hot body is used for
measurement of temperature by comparison
of colour.
.
There are two types of Pyrometer.
 OPTICAL PYROMETER
 RADIATION PYROMETER
.
 The PYRO optical pyrometer temperature sensor for
non contact high temperature measurement operates by
allowing the operator to compare the intensity.
 It is based upon the fact that all black bodies do have
the same incandescence color at a given temperature.
Optical Pyrometer is works on principle of matching the
brightness of hot object.
Pyrometre
 It consist of focusing lense which radiate energy
 Absorption screen in order to absorb some radiate
energy.
 Filament which is used for adjustment of
brightness rate
 Filter for filtering the target and filament colour
that should be easily comparable in term of
brightness .
Diagram
Optical pyrometer
Optical Pyrometers works on the basic
principle of using the human eye to match the
brightness of the hot object to the brightness of a
calibrated lamp filament inside the instrument.
The optical system contains filters that restrict the
wavelength-sensivity of h devices to a narrow
wavelength band around 0.65 to 0.66 microns.
Other reduce the intensity so that one instrument
can have a relatively wide temperature range
capability.
 FLEXIBLE
 PORTABLE
 EASY TO USE
 LIGHT WEIGHT
 CAN MONITOR MOVEABLE OBJECTS
 NONO CONTACT TYPE
 ACCURATE
 EXPENSIVE
 HUMAN ERRORS
 CONTINUOUS MONITORING
 CONTROLLING PURPOSE
 NOT USEFUL FOR MEASURING TEMP OF LEAR GAS
 AT HIGH TEMP, FILAMENT ERODES FREQUENTLY
The PYRO MicroTherm radiation pyrometer is ideal for many small
target laboratory and industrial applications. It is extremely useful
when measuring small targets that do not fill the entire field of view.
 Lamp Filament Wire
 Cathodes
 Wire Drawing
 Crystal Growth
 Calibration Standard
