Glossary

X, Port - It refers to pilot signal port.

X-ray Emission, Proton Induced PIXE - Its an X-ray emission spectrometer which is based on physics. It separates electrons from hydrogen atom and then accelerator drives protons at high speed for colliding with target/specimen. The spectrometer is capable of evaluating 72 elements simultaneously in one sample.

Y, Port - It refers to pilot signal port. .

Yield Strength - Its stress at which material exhibits specified deviation from proportionality of stress and strain. .

Young's Modulus - It's the ratio of simple tension stress that is applied to material to resulting strain parallel to tension.

Z Factor - here factor is defined by relation Z = PV/NRT and is based on assumption that at same reduced pressure and temperature all gases have same compressibility factor. .

Zero-lapped - It's a critical-center condition where spool land width is identical to port width. .

ZETA Rating - It's a contaminant abrasion rating system which allows Omega Life of component to be transformed to Zeta Life to reflect abrasive severity of the environmental contaminant. .

Z-Transform - It converts difference equations into algebra form and is normally used for handling discrete/digital samples.
