7.5.3 How to mount large size sensor to pipe
q q q q q Height adjustment of guide plate
• Place the sensor on the pipe surface in parallel
with the pipe axis.
• Loosen the guide plate fixing screw and slide
the guide plate until its edge and transmitting
surface touch the surface of pipe.
• Then tighten the fixing screw.
w w w w w How to determine the length of wire rope
• Place the sensor on the marked lines and fit the
wire rope and fastening spring.
• Loosen the wire clip and pull the wire rope
until the overall length of fastening spring
approximates 180mm. Then tighten the wire
clip.
(The fastening spring has a free length of
110mm.)
• While fixing the wire rope, remove the sensor.
e e e e e Mounting of sensor
• Wipe off contaminants 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 fit the wire rope.
• Align the matching mark of sensor with the
m a r k e d l i n e . I n a d d i t i o n , m a k e t h e
transmitting 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.
