The Particle Quantifier Index (PQ) measures the amount of ferromagnetic particles in the oil sample - often a sign of wear in steel-containing components. It provides a rapid and quantitative indication of severe abrasion injuries.
The sample is exposed to a magnetic field, and the particle amount is calculated based on how strong the signal is. The result is not affected by particle size, but total mass of ferrous material.
The customer receives an important notification of potentially serious machine wear and can react before the problem develops into a breakdown.
