Section 2 — INSTALLATION
TABLE 2.2 – SPOT SIZE VS. SEPARATION DISTANCE
Spot Size/Separation Distance relationships are
given in Table 2.2. As shown in the table, MOD-
LINE 4 models are available with Standard
Resolution, High Resolution and Very High
Resolution.
NOTE: Series 22 instruments are not available
with Very High Resolution; Series 43 instruments
are available only with Standard Resolution.
The Resolution is designated by model number
Block C labeled on the back of the identification
plate on the side of a standard casting.
A 0 designates Standard Resolution; a 1 desig-
nates High Resolution; and a 2 designates Very
High Resolution.
Determine the Resolution rating (Standard, High or
Very High Resolution) of your instrument, then
refer to Table 2.2 for details on the optical charac-
teristics.

Formula
If D > 8 inches or 203 mm
dinches = 0.1 (D – 8) + 0.3
dmm = 0.1 (D – 203) + 8
For Sensors with water-cooled castings, multiply
spot size (d) from table or formula by 1.1
Example: If d is 8.2 inches per table or diagram,
then d for water-cooled casting is:
d = 8.2 x 1.1 = 9.02 inches

d = Spot Size
D = Separation Distance
Formula
If D > 15 inches or 380 mm
dinches = 0.13 (Dinches – 15) + 1.0
dmm = 0.13 (Dmm – 380) + 25
Example:
If D = 45 inches,
d = 0.13 (45 – 15) + 1.0
= 0.13 (30) + 1.0 = 3.9 + 1.0
= 4.9 inches
= 5 inches
For Models 43-04F and 43-02C only:
dinches = 0.17 (Dinches) + 1.0
dinches = 0.17 (Dmm) + 25

Formula
If D > 60 inches or 1500 mm
dinches = 0.05 (Dinches – 60) + 2.0
dmm = 0.05 (Dmm – 1500) + 50
If D < 60 inches or 1500 mm
dinches = 0.017 (Dinches) + 1.0
dmm = 0.017 (Dmm) + 25
Example:
If D = 90 inches,
d = 0.05 (90 – 60) + 2.0
= 0.05 (30) + 2.0 = 1.5 + 2.0
= 3.5 inches
