•  Clean the drill hole and the area around it with compressed 
air; roughen the surface around the drill hole with sandpaper  
(grade 220).
•  Clean the contact faces at the adapter and the machine with 
solvent.
•  Allow the contact faces to dry, apply a thin layer of screw locking 
agent (LOCTITE 243) to improve signal propagation. 
•  Screw the threaded bolt into the sensor and tighten it with  
a size 4 Allen key. 
•  Screw the sensor into the mounting hole and tighten it with  
a size 19 socket wrench. Tightening torque: 10 – 20 Nm!
•  Check the sensor for proper fixture (sensor must not rock).
Notes
Do not apply an excessive torque as this could damage the machine 
part or the thread at the sensor. If the tightening torque is too low, 
there might be insufficient contact between the sensor and the 
measurement location. Incorrect tightening torques result in incor-
rect measurements!
When installing sensors to machine parts that are not earthed  
(e.g. belt-driven fans), connect the sensors to an earthing conduc-
tor to prevent static charging.

Note
Before mounting the adapter, shut down the machine. Do not 
restart the machine for a period of 24 hours to prevent mechanical 
vibration while the adhesive is curing.
If the machine is restarted before the adhesive has properly 
 
cured, the adapter might become loose. This can cause damage 
to the sensor and / or to the machine. Incorrectly installed adhesive  
adapters can result in poor signal propagation to the sensor and  
measuring errors.
