Leadwire
Selection

Page 1 of 7
Leadwires, properly selected and installed,
should play a passive, yet critical, role in strain
measurement. Their primary function is to deliver
power to those portions of the strain gage circuit
remote from the measurement instrument and to
retrieve the strain-induced measurement signal from
the gage installations. Ideally, leadwires take
nothing from the measurement signal and add nothing
to it.
While all leadwires do influence the signal to some
extent in actual practice, Micro-Measurements offers
a complete line of wires and cables which can be used
to minimize leadwire errors. Following is a brief
outline of the more important selection
considerations:
-
Temperature Capabilities
-
Number of Conductors
-
Diameter of Conductor
-
Solid vs. Stranded Wire
-
Twisted/Shielded Cables
-
Adhesion to Environmental
Protection
