5.2 Emissivity
Emissivity is the ability of an object to emit or absorb energy. Perfect
emitters have an emissivity of 1, emitting 100% of incident energy.
An object with an emissivity of 0.8 will absorb 80% and reflect 20%
of the incident energy. Emissivity is defined as ratio of the energy
radiated by an object at given temperature to the energy emitted by a
perfect radiator at the same temperature. All values of emissivity fall
between 0.1 and 1.0.
Noncontact temperature sensors measure IR energy emitted by
the target, have fast response, and are commonly use to measure
moving and intermitent targets, targets in a vacuum, and targets that
inaccessible due to hostile environments, geometry limitations, or
safety hazard. The cost is relatively high, although in some cases is
comparable to contact devices.
6. MAINTENANCE
Cleaning the lens: Blow off loose particles using clean compressed
air. Gently brush remaining debris away with a camels hair brush.
Carefully wipe the surface with a moist cotton swab. The swab may
be moistened water.
Note: DO NOT use solvents to clean the lens.
Cleaning the housing: Use soap and water on a damp sponge or soft
cloth.
