Load
Pins
When overload protection
and/or load indication is to be installed in a conveyor, crane or other device,
the PIAB SLC is the ideal solution. The PIAB SLC Load Pin easily replaces the
existing shaft at an equalizing pulley or in other parts of the construction.
The PIAB SLC Load Pin should be installed as close as possible to the
force/load for best accuracy. Both the PIAB SLC Load Pin and the PIAB LCA
Amplifier are designed to withstand extreme environmental conditions for a long
operation time.
PIAB
SLC Load Pin function
The PIAB SLC Load Pin is
designed as a shaft. Built into the shaft is a number of foil-strain gauges for
sensing the deformation of the shaft during exposure to load. Shear forces
appear in the section between the support and the applied load. Those shear forces
are relative to the load on the PIAB SLC Load Pin. Since the strain gauges are
positioned in the centre of the PIAB SLC Load Pin, little or no influence is
derived from bending or torsion forces.
The strain gauges are
fed with 10 VDC from PIAB LCA Amplifier. The strain gauges deliver a signal to
the amplifier (mV/V). This signal is converted in the PIAB LCA Amplifier to a
current signal of 4-20 mA which is extremely resistant to interference. The
transducer amplifier should be installed as close as possible to the PIAB SLC
Load Pin. The PIAB SLC Load Pins can be designed for very small to very large
dimensions and various capacities.
