Avery Berkel Technical Specification
T109
Applications
This load cell is designed to
operate with the weigh pan
mounted directly to it.
The base and weigh pan should
be sufficiently rigid to prevent
undue deflection when subjected
to eccentric loads.
High tensile cap head screws are
recommended for load cell
mounting, with a minimum of
15 mm thread engagement and
tightened to a torque of 10Nm.
Overload Protection
To give the load cell overload
protection, five stops are
recommended. A single centre
stop may be suitable in less
demanding applications.
