7.4 How to mount small size (standard) sensor and small
outer diameter sensor to pipe
q Loosen the lock nut and slide the sensor so as to
meet the mounting dimension and then tighten
the nut.
w Apply a coat of silicone grease to the
transmitting surface of the sensor. Spread the
compound over the entire area.
Keep the sensor retracted by turning the element
holder counterclockwise.
After cleaning the surface of the pipe, the sensor
should be mounted.
e Fix the both ends (saddles) of the sensor to the
pipe by cloth belts.
Mounting will be facilitated by winding the cloth
belts on the pipe in advance.
Cloth belts are usable at 80
°
C or lower. If
beyond 80
°
C, stainless steel belts should be
used.

r Make sure the sensor is mounted in parallel with
the pipe axis and the mounting dimension is
right. Then, turn the element holder clockwise
until the sensor comes in close contact with the
pipe.
Stop turning the element holder when it stiffens
because the transmitting surface comes in
contact with the pipe surface. Be careful not to
turn the holder excessively.
