Fibroptic Thermometer
Fibroptic Thermometer
2.1 Positioning the Optic Head
If your UNO Fibroptic thermometer is fitted with a Laser Alignment Unit (e.g. U1
600/1600 C
Y L), the laser be used to aid the installation of the themometer optic
head by defining the target area on which the optic head is aligned. This is
particularly useful in applications where the target size is small and/or where
correct alignment is critical. For more information on the Laser Alignment Unit,
refer to Section 4.0.
In many cases, there are few options on location of the optic head, as this is
generally dictated by the particular measurement application. Observe the
following precautions;
(i) If your thermometer is an 'U' series thermometer (e.g.
U1 600/1600 C
L), it must be positioned such that, at the chosen target distance, the
target is large enough to completely fill the optic head's field of view.
Refer to the target size tables, Section 4.0. The thermometer's view
of the target area must not be obstructed.
(ii) Ensure that the angle between the optic head's line of sight and the
target area is as near to 90° as possible. However, if this is not possible,
a viewing angle of up to 45° is acceptable.
(iii) If the optic head is located in an atmosphere containing a high
proportion of dust/smoke etc, an air purge must be used in conjunction
with the optic head. This prevents the lens from becoming dirty. Refer
to the Installation Guide supplied with the mounting/purge assembly.
2.1.1 Installing the optic head
The optic head can either be mounted directly into a threaded hole in a user-
supplied mounting plate, or connected to one of the range of Land Fibroptic
thermometer mountings by means of the 'Quick Release Fitting', Land Part Nº
029.591.
To mount the optic head in a plate
(i) Refer to Fig. 4(a). Unscrew the clamp nut nearest the lens on the optic
head.
(ii) Screw the optic head into an M22 x 1.5P threaded hole in the plate.
(iii) Re-attach the clamp nut onto the optic head. Tighten the nut so that
the mounting plate is held securely between the two clamp nuts on the
optic head.
To mount the optic head into Land Fibroptic thermometer mountings
(i) Refer to Fig. 4(b). Screw the two clamp nuts up as far as they will go
on the thread on the optic head.
(ii) Screw the optic head into the 'Quick Release Fitting'.
(iii) Attach the fitting, plus the optic head, to the Land Fibroptic thermometer
mounting by means of the twist lock on the Quick Release Fitting.
