3 Principle of Operation
Fig. 1 shows the eld of view for a standard System 4 Thermometer. The axis
of the eld of view is xed at the centre of the thermometer lens and is at
right angles to the front face of the thermometer.
Fig. 2 shows the eld of view for a Thermometer tted with the Target
Orbiting (TO) option. The target size at any given distance is identical to
that of the corresponding standard Thermometer. However, the eld of view
rotates about a cone of half-angle 2°, centred on the opto-mechanical axis
of the Thermometer. The frequency of rotation is 3Hz. The Target Orbiting
Thermometers achieve a peak temperature output in excess of 99.5% of
value (in degrees) for any target surface whose width is greater than, or
equal to, 1.2 times the target spot diameter (1.5 times for 200:1 eld of view
thermometers).
The Target Orbiting option is designed for use on moving or intermittent
targets. In a standard System 4 Thermometer, the eyepiece graticule denes
the target spot. In a Target Orbiting Thermometer, the graticule denes the
orbit of the centre of the target spot (refer to Fig. 3 overleaf). It can be
seen from Fig. 3 that, for a narrow object (e.g. wire), it is possible that the
target may not be covered by the graticule for considerable periods, due
to lateral movement of the product with respect to the thermometer. In a
Target Orbiting Thermometer, this is not a problem as the Thermometer can
be sighted so that the graticule covers the limits of lateral movement. This
means that an accurate, valid temperature reading will be obtained by the
thermometer at least three times per second. When used in conjunction with
the ‘Peak Picking’ function of either the Landmark Graphic, Landmark Classic
or Landmark Basic processor, the true temperature of the target can be
ascertained.

Target Orbiting Thermometer User Supplement
3.1 Suggested settings for use in 'Peak Picker' mode
1) Use the Landmark Graphic processor in Reset mode, to ensure that the
indication falls to zero when no hot material is within the target orbit.
2) The Threshold level for the Peak Picker is the temperature above
which the Peak Picker is active. The lowest selectable level is the span
minimum of the thermometer connected, but otherwise is decided
entirely by the user.
3) Set the On delay to zero.
4) Set the Off delay to >0.4s, to ensure that the indication does not reset
to span minimum within one orbit.
5) Set the Decay Rate to 1°C/s, so that genuine cooling of the target
may be tracked. Target surfaces that cool quickly (e.g. thin wires) may
require a faster decay rate to track the cooling accurately.
