3.1 Mechanical installation
Risk of injury from touching the moving measuring tape or moving parts
during operation
•
Operate the sensor only with a suitable protective device (eg. tape cover) to
prevent injury!
Choice of installation position
•
Select a protected installation position for the measuring tape.
This prevents damage of the measuring tape.
•
Preferably mount the sensor with the tape outlet pointing downwards.
This prevents liquids from entering through the tape outlet.
•
Screw the sensor onto a flat surface or provide a three-point mounting.
This avoids distortion and damage to the sensor.
Fitting the sensor
Depending upon the sensor model, holes in the base plate or threads in the sensor housing enable
attachment of the sensor. Dimensions required are listed in the data sheet and the catalog.
Tape attachment device
For fastening the tape clip the 5 mm dia. bore is provided.
Damage to the measuring tape due to incorrect installation
•
Prevent the measuring tape from binding.
•
Ensure sensor is installed and aligned correctly to prevent damage to tape. Where
required use a tape diverting pulley WBR1.
Damage to the measuring tape due to an axial twist
•
Do not exceed the maximum twist of 90° of the measurement tape
•
A single tape twist of 90° is possible. Before twisting the tape, a distance of at least
30 cm from the tape outlet must be kept in axial direction. While retracting the tape,
it must be twisted back at the distance of at least 30 cm before the tape entirely
enters the tape outlet.
