Datasheet

Typically, you should mount the sensor
onto an even and smooth support sur-
face, for example a plastic, glass or
metal plate. Unlike the standard cells,
the HD-FSR can also be mounted on
slightly bent rubber or foam layers.
 To avoid mechanical pre-load and
false signals, do not bend the sen-
sor in the active area to a radius of
< 120 mm.
 To avoid broken conductor lines,
do not bend the connection tail to
a radius of < 5 mm.
 All sensors feature an air vent. Take
care not to block it and to avoid
liquids from penetrating through it.
 All sensors feature a backing ad-
hesive with a release liner. If you
need to remove the liner, take care
that surface and material proper-
ties match the backing adhesive.
Important Application Information
The sensor can be read out with or with-
out calibration, depending on the type of
use and the accuracy required:
 To avoid additional process costs for
individual cell calibration, all sensors
can be read out without calibration
by using the typical response curves
shown on pages 24 and 25. This
may be useful if you have a high vol-
ume market.
 To ensure high sensor accuracy and
repeatability, all sensors can be
calibrated by three-point pressure
response curve interpolation. Thanks
to the very high environmental and
mechanical robustness of the new HD
sensor, no recalibration is needed
during the sensor’s lifetime.
The sensor shows a very low hysteresis
in the pressure response curve compared
with the standard single cells described
on pages 4 - 15 (about 20 %):
 Hysteresis for HD 001: 3 %
 Hysteresis for HD 002: 8 %
