extreme temperatures, moisture, shocks,
or vibration.
§ If a service problem with the device
should occur: Contact Sartorius Service.
Intended Use
The weigh cell is intended to be used to
weigh under difficult space conditions
and for exact weight determination
during ongoing production.
The weigh cell must be installed in a
device or system, such as a measuring
device or a production machine. The
weigh cell must be secured to the
device or system.
The optional control unit YAC01ED can
be connected to the weigh cell.
! Weigh cells are additional devices for
installation in other devices or sys-
tems. An EU Declaration of Confor-
mity must be issued for the final
device or system.
System Description
The products are comprised of two
components:
– A compact weigh cell that must be
secured at three points
– Electronics unit
– These compact weigh cells can be used
to determine weights within restricted
space.
