0.08mm Evanohm Nickel Alloy Filament Wire for Shear strain gauges

1. General Description

Nichrome resistance alloy is an ideal electrical heating material that can be used up to 2150oF or 1200oC. It has suitable hot strength and extremely high electrical resistance. Nichrome alloy (Strip and Wire) produces a strong chromium oxide layer upon heating that provides outstanding oxidation resistance at the elevated temperatures. It has high melting temperature about 1350oC. Nichrome wire offers a special resistance range of 5500 ohm/m.

We offer fine gauge wire for a broad range of applications including low temperature heating in the electronic equipments such as variable frequency controller for example potentiometers, pressure transducers, detonators, ceramic resistance, wire wound resistance, lead wire and also strings for musical instruments.

Nichrome 80 resistance heating alloy is suitable for reconstructing your atomizer and is particularly excellent for sub-ohm coils. It has smaller resistance per unit length than Kanthal hence it heats up more quickly and is recommended over Kanthal for various applications.

2. Strain Gauges

A strain gauge (also spelled strain gage) is a device used to measure strain on an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. The gauge is attached to the object by a suitable adhesive, such as cyanoacrylate. As the object is deformed, the foil is deformed, causing its electrical resistance to change. This resistance change, usually measured using a Wheatstone bridge, is related to the strain by the quantity known as the gauge factor.

A strain gauge takes advantage of the physical property of electrical conductance and its dependence on the conductor's geometry. When an electrical conductor is stretched within the limits of its elasticity such that it does not break or permanently deform, it will become narrower and longer, which increases its electrical resistance end-to-end. Conversely, when a conductor is compressed such that it does not buckle, it will broaden and shorten, which decreases its electrical resistance end-to-end. From the measured electrical resistance of the strain gauge, the amount of induced stress may be inferred.

A typical strain gauge arranges a long, thin conductive strip in a zig-zag pattern of parallel lines. This does not increase the sensitivity, since the percentage change in resistance for a given strain for the entire zig-zag is the same as for any single trace. A single linear trace would have to be extremely thin, hence liable to overheating (which would change its resistance and cause it to expand), or would need to be operated at a much lower voltage, making it difficult to measure resistance changes accurately.
