BRIX
Degrees Brix (symbol °Brix) is a measurement of the mass ratio of dissolved sugar to water
in a liquid. A 25 °Bx solution is 25% (w/w), with 25 grams of sugar per 100 grams of solution.
Coriolis
The Coriolis effect is an apparent deflection of moving objects from a straight path when they
are viewed from a rotating frame of reference. The effect is named after Gaspard-Gustave
Coriolis, a French scientist who described it in 1835. The Coriolis effect is caused by the
Coriolis force, which appears in the equation of motion of an object in a rotating frame of
reference.
EHEDG
European Hygienic Engineering & Design Group was founded in 1989 to promote hygienic
engineering in the European food industry. EHEDG provides practical guidance on hygienic
engineering aspects of manufacturing safe and whole some foods.
EMC
Electromagnetic compatibility (EMC) is the branch of electrical sciences which studies the
unintentional generation, propagation and reception of electromagnetic energy with
reference to the unwanted effects (Electromagnetic Interference, or EMI) that such energy
may induce. The goal of EMC is the correct operation, in the same electromagnetic
environment, of different equipment which use electromagnetic phenomena, and the
avoidance of any interference effects.
Fraction
Fraction designates a proportional relation between an object part and the object whole. For
example, the fraction 3⁄4 represents three equal parts of a whole object, divided into four
equal parts.
IP
An IP (Ingress Protection) number is used to specify the environmental protection rating of
enclosures around electronic equipment. These ratings are determined by specific tests. The
IP number is composed of two numbers, the first referring to the protection against solid
objects and the second against liquids. The higher the number, the better the protection. For
example, in IP67 the first Number (6) means that the device is totally protected against dust,
and the second (7) that it is protected against the effect of immersion between 15cm and 1m
