Weldable Strain Gauges continued
Arc-Weldable Gauge Advantages
q
Arc-welder readily available.
q
Can be tensioned in the field.
q
Can be removed from mounting blocks and reused.
q
Gauge cannot be damaged by welder.
Disadvantages
q
More costly than spot-weldable gauge.
q
Higher profile than spot-weldable gauge.
Spot-Weldable Gauge The spot-weldable gauge operates as explained above, but consists
of two components: (1) the strain gauge itself, which is welded to
the surface, and (2) the electromagnetic coil, which is mounted on
top of the strain gauge.
Advantages
q
Quickly installed.
q
More economical than resistance strain gauges.
q
Durable.
q
Patented, low-profile design reduces error caused by bending of
the structural member.
Disadvantages
q
Requires spot-welder.
q
Pickup sensor must be protected during installation.
q
Installed gauges can be over-stressed by careless handling of
member.
q
Gauge attrition likely if installed on driven piles.
