2. Design and function
2.1 Overview
2.2 Description
The single point load cell is intended for the measurement of static compression forces
in weighing applications. The single point load cell consists of a measuring spring on
which strain gauges (SGs) are applied.The measuring body is made of aluminium
and is elastically deformed by a force introduced in the force direction.The resulting
mechanical tensions are measured by the strain gauges and output as an electrical
output signal.
The strain gauges are arranged so that two of them are tensioned and the other two are
compressed when a force is applied to the single point load cell.
The single point load cell circuit includes correction and compensation resistors to elimi-
nate unwanted effects on the zero signal and characteristic value.

4. Transport, packaging and storage
4. Transport, packaging and storage
4.1 Transport
Check the single point load cell for any damage that may have been caused by
transport. Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during inter-
nal transport, proceed carefully and observe the symbols on the
packaging.
▶
With internal transport, observe the instructions in chapter 4.2
“Packaging and storage”.
As precision measuring instruments, single point load cells require careful handling
during transport and mounting. Load impacts during transport (e.g. hitting a hard
surface) can lead to permanent damage, resulting in measuring errors in the subse-
quent measuring operation.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change
in installation site, sending for repair).
The measuring spring is manufactured completely from aluminium and corresponds to
IP65 ingress protection.
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +60 °C
■
Humidity: 35 ... 85 % relative humidity (non-condensing)
Avoid exposure to the following factors:
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Dust, dirt, and other objects may not be deposited in such a way that they form a
force shunt with the measuring spring, since this will falsify the measuring signal.
