How to apply sensors
NOTE!
i
When mounting sensors at the measuring point, they must always be
isolated, i.e. separated from any potential.
NOTE!
i
Since there is very little space available inside a battery, the sensors are
equipped with very thin cables. Accordingly, these cables are sensitive
and can only withstand limited mechanical stress. Therefore, sensor
cables and flexible circuits should be handled very carefully.
"
Do not kink sensor cables and flexible circuits.
"
Make sure that cables and flexible circuits are not mechanically stres-
sed. Provide strain relief if necessary.
"
Do not bend the sensor cable by 90° directly at the end of a solder lug.
NOTE!
i
When choosing the measuring point, also make sure that a sensor will not
be exposed to mechanical strain after mounting.
"
Never expose sensors to mechanical strain.
Sensor designs
Currently, single sensors and flexible circuits are used. Both types are available with only
individual sensors and as sensor assemblies. Fig. 4-4 and Fig. 4-5 show units with unsealed
sensors. These units are also available with sealed sensors.
Fig. 4-4: Single sensor, top view
Fig. 4-5: Sensor assemblies (flexible circuit)
In both versions, the lower side of the sensor is electrically isolated (see Fig. 4-6). This
means that no further isolation material is required when mounting the sensors with the
lower side towards the measuring point, as recommended by CSM.
