Maintenance
Speed sensors contain no moving parts and are therefore declared as
'maintenance-free devices' by the manufacturer. Nevertheless, note that
speed sensors are part of the system and are therefore subject to various
ambient factors (heat, cold, motor abrasion, etc.). Therefore, they are to be
included in the servicing concept of the system maintenance. Connections
and cabling, their installation as well as downstream processing and evalu-
ation components in particular are to be included in the maintenance con-
cept.
The manufacturer recommends to check the speed sensors at regular in-
tervals as part of system maintenance. The sensors should be cleaned if
soiled. If on inspection the speed sensor is found to be damaged, replace-
ment is recommended even if the damage does not directly cause signal
loss. Damaged connections and cabling should also be replaced immedi-
ately. Function tests should be carried out afterwards to ensure trou-
ble-free operation. This preventative maintenance avoids failures and con-
sequential damage.
