Installation procedure
5.2 PROCEDURE FOR INSTALLATION WITHOUT BUSHING – APPLICATION: ELECTRIC
MOTOR
For the correct mounting of the sensor on the motor in the center position without using the knurled bushing,
the following sequence of steps must be performed:
1. With the motor turned off and observing all the safety instructions indicated in this manual, locate the
5
motor position where the sensor must be fixed. According to the positioning guidelines indicated in
chapter 2 on page 4-2 and make the mark to make the hole.
2. For motors with fins, drill a through hole in the fin. In motors without fins, make a 13 mm deep hole. To
that end, use a 3.3 mm diameter drill bit.
3. Using an M4 tap, make the thread in the hole drilled in step 2.
4. Using a 3 mm Allen wrench, screw the sensor into the knurled bushing and check its tightness. The
maximum tightening torque is 4.0 Nm. As per Figure 5.2 on the page 5-1.
5.3 INSTALLATION PROCEDURE – APPLICATION: OTHER ASSETS
For the correct fixation of the sensor with a screw in other positions/assets where you want to monitor
vibration and temperature, you must perform the following sequence of steps:
1. With the equipment turned off and observing all the safety instructions indicated in this manual, define
a position for fixing the sensor. This position depends on what you want to measure. For example, if
the variable of interest is vibration, you should avoid mounting it close to the asset fixation point; if the
variable of interest is temperature, you should install the sensor in a location with high temperature.
Mark the point to drill the hole.
2. By inserting a knurled bushing:
(a) Drill a 5.9 mm (15/64") hole at least 9 mm deep.
(b) Using a hammer, insert the knurled bushing into the hole until the ring touches the surface of the
asset. (Note: if the bushing is inserted without the aid of a hammer, it means that the hole has a
slightly larger diameter and, in this case, the sensor's fastening to the motor will be compromised.
Therefore, it is necessary to drill a new hole for the correct fastening of the bushing).
3. By creating a thread:
(a) Drill a 3.3 mm hole at least 13 mm deep.
(b) Using an M4 tap, make the thread in the hole drilled in the previous step.
4. Using a 3 mm Allen wrench, screw the sensor into the knurled bushing and check its tightness. The
maximum tightening torque is 4.0 Nm. As per Figure 5.2 on the page 5-1.
