Intervening Objects

Errors can be caused by objects between the

MODLINE 4 and target. Any such object that hap-

pens to be inside the Cone of Vision will be visible

to the detector, and will cause an error in the tem-

perature reading.

Before selecting the mounting location, consider

the sight path just as you do when you aim a cam-

era to take a photograph. Try to picture the Cone

of Vision, is within the cone, select a different view-

ing angle.

2.7g

Reflections

Reflections from other radiating objects represent

a potential source of error in your temperature

readings. The total radiation seen by the MOD-

LINE 4 will be a combination of intrinsic radiation

plus reflected radiation.

Examples of interfering sources are hot furnace

walls and heating elements that are hotter than the

target object.

Most reflection problems can be eliminated by

changing the viewing angle or shielding the reflec-

tions. Suggestions for anticipating and eliminating

common reflection problems are provided in

Section 6. However, if you are faced with unusual

reflection problems, call IRCON Technical Service

for recommendations.

Use of Windows

If it is necessary to view the object through a win-

dow, as is the case when the object is being heat-

ed in a vacuum or inert atmosphere, be careful in

selecting the window material. The material must

have good transmission characteristics in the

wavelength band of the MODLINE 4 series.

A guide to appropriate windows for all MODLINE 4

Series is provided in Section 3.4.
