8.5.5 How to mount large size sensor to pipe
(1) Height adjustment of guide plate
• Place the sensor on the pipe surface in parallel
with the pipe axis.
• Loosen the guide plate fi xing screw and slide
the guide plate until its edge and transmitting
surface touch the surface of pipe.
• Then tighten the fi xing screw.

(2) How to determine the length of wire rope
• Place the sensor on the marked lines and fi t the
wire rope and fastening spring.
• Loosen the wire clip and pull the wire rope
until the overall length of fastening spring
approximates 180mm (7.1"). Then tighten the
wire clip.
(The fastening spring has a free length of
110mm or 4.3")
• While fi xing the wire rope, remove the sensor.
(3) Mounting of sensor
• Wipe off contaminates from the transmitting
surface of sensor and the sensor mounting
surface of pipe.
• Apply the silicone grease on the transmitting
surface of sensor wile spreading it evenly.
• Film thickness of the silicone grease should be
about 3mm.
• Spread the wire rope near the marked lines
in the left-right direction, bring the sensor in
close contact and fi t the wire rope.
• Align the matching mark of sensor with the
marked line. In addition, make the transmit-
ting direction marks of sensors face each
other.
• Make sure the matching mark of sensor is
aligned with the marked line and connect the
coaxial cable to the converter.
Note) Do not pull the coaxial cable. Other-
wise, the sensor will be activated to
disturb measurement.
