parts
8 Decommission
All sensors must be dismantled professionally. Do not strike sensor housings with tools. Do not apply bending
moments on the sensor, e.g. through levers. The torque sensor must be supported to avoid falling down during the
dismantling.
9 Transportation and Storage
The transportation of the sensors must occur in suitable packing.
For smaller sensors, stable cartons which are well padded are sufficient (e.g., air cushion film, epoxy crisps, paper
shavings). The sensor should be tidily packed into film so that no packing material can reach into the sensor (ball
bearings). Larger sensors should be packed in cases.
