Sensors eye Fluids And Lubricants
bulk-phase separation has not taken place. Finally, at still higher concentrations water droplets coalesce and completely separate from the oil. Depending on fluid densities, this so-called "free" water settles to the bottom of the tank with some synthetic and hydrocarbon-based fluids or migrates to the top...

Fluid Performance Factors
. Compressibility is the degree to which a fluid undergoes a reduction in volume under pressure. As a rule of thumb, compressibility is about 0.5% for each 1,000-psi pressure increase up to 4,000 psi. Compressibility, or bulk modulus, has its greatest effect on performance in servo applications...

Fluid Transfer Pumps
Fluid-handling or transfer devices are not basically concerned with the modulation or transfer of power, but only with the movement of fluid. Two major types of fluid-transfer pumps are positive-displacement (either bulk-handling or metering pumps) and nonpositive-displacement (centrifugal...

Understanding Fluid Degradation
if the TAN number is greater than 1.0 to ensure maximum evacuation of the spent fluid prior to refilling. Thermal degradation. Thermal degradation or thermal cracking is the breaking of carbon - carbon bonds in the fluid molecules by heat in excess of the fluid's recommended maximum bulk temperture...

To perform reliable measurements, it is important to diffuse the surface contaminants into the substrate bulk and to passivate the surface. Passivation is necessary because surface...
