Oil Flow Switch, Compensates for Viscosity Change In Fluids
Quick Specs...
Overview / Design Principle:
A unique, patented piston design assures accuracy within 20% over a full range of viscosities - from 40 to 1000 SSU. Ideal for use in applications where liquids of different viscosities are blended; or for use in lubrication systems where oil flow monitoring is critical at start-ups. Switch compensates for viscosity changes automatically. Each unit is factory preset, using 300 SSU oil, for actuation at specified flow rates.
