Thermocouple type for tungsten versus tungsten 26 percent rhenium. Also known as acceleration due to gravity; equal to 980 cm/sec ²(32.2 ft/sec ²) on the surface of the earth s. 3. Specific gravity

In equipment corrosion specifications, the designation for one measure of mild environmental contamination, as defined in ISA standard ISA-71.04 1985 G1 represents less than 300 per month of copper corrosion (for electrical terminals).

In equipment corrosion specifications, the designation for one measure of moderate environmental contamination, as defined in ISA standard ISA-71.04 1985. G2 represents less than 1,000 per month of copper corrosion (for electrical terminals).

In equipment corrosion specifications, the designation for one measure of harsh environmental contamination, as defined in ISA standard ISA-71.04 1985. G3 represents less than 2,000 per month of copper corrosion (for electrical terminals).

Variant spelling of gauge.

1. The ratio of output signal magnitude to input signal magnitude. When gain is less than one this is usually called "attenuation." [ISA-26 1968] 2. The relative degree of amplification in an electronic circuit. 3. The ratio of the change in output to the change in the input that caused the change. 4. In a controller, the reciprocal of proportional band. For example, if the proportional band is set at 25 percent, the controller gain is 4. Proportional band can be expressed as a dimensionless number (gain) or as a percentage.
