1.1 Product Summary
1. Theory of Measurement
Every object emits infrared energy in accordance
with its temperature. By measuring the amount of
this radiant energy, it is possible to determine the
temperature of the emitting object.
2. About infrared
Infrared radiation is a form of light (electromagnetic
radiation), and has the property that it passes easily
through air, while it is easily absorbed by solid
matter.
With 3460-50 2D THERMO HiTESTER, accurate
measurement is possible, irrespective of the air
temperature or the measurement distance.
3. Emission Thermometer Structure
Infrared radiation which has been emitted from the
object is focused upon an infrared radiation sensor,
via an optical system which includes a lens which is
transparent to infrared radiation, an 8
μ
m cuton
filter, etc..
The output signal from the infrared radiation sensor
is input to an electronic circuit along with the
output signal from a standard temperature sensor.
