The wire table computes (a) the length of wire necessary to achieve a specific
resistance based on a specific wire alloy and gauge (diameter), or (b) the resistance of a
specific wire. All calculations are based on a wire temperature of 68 deg F (20 deg C).

All the circuit refinement calculations yield the ohmic values for one or more resistors needed
to achieve the desired compensating or setting. The resistive components for physically
producing these values can be either bonded foil types, discrete "component" resistors (metal
film), or wire resistors made by spooling a small length of insulated, single-conductor wire.
Bonded foil gages are generally preferred because they are similar in construction to strain
gages and, therefore, perform similarly to strain gages when the transducer undergoes a
change in temperature. (They exhibit similar "thermal tracking" characteristics.) However, in
less demanding applications, or when the lowest component cost is important, the necessary
resistance can be achieved with specific lengths of wire of various alloys and gauges
(diameters). The wire table computes the lengths of these wires.
