Americium-241 has been used industrially in fluid-density gauges, thickness gauges, aircraft fuel gauges, and distance-sensing devices, all of which use its gamma radiation.
The thickness of the coatings was measured by eddy current coating thickness gauge.
The effects of a number of key geometric parameters such as angle thickness, gauge distance, depth of beam, bolt size and length of angle were considered.
Magnetic thickness gauge was used to determine the thickness of the coating and the bath sludge weight was specified to determine the bath efficiency.
The experimental results offer direct information on the influence of important geometric and material properties, such as angle dimensions, column face thickness, gauge length and bolt class, on the key response characteristics including stiffness, strength, energy dissipation and failure mechanism.
This results can be used during the designing of high-temperature X-ray and gamma-radiation detectors for radiation hot rolling thickness gauges which are widely used in the metallurgy.
Although this probe arrangement is similar to that of a coulometric thickness gauge, the porous nature of the battery plate results eventually in full discharge of the entire specimen.
Further, the coating thickness as measured by eddy current thickness gauge and SEM coating cross section confirmed that the 1000 Hz frequency and 20% duty cycle produced a thicker coating.
The phase composition, roughness, thickness, surface morphology and cross-sectional microstructure of the coating were assessed using X-ray diffraction (XRD), optical profilometer, eddy current thickness gauge and scanning electron microscope (SEM).
It is also used as a source in thickness gauges and has been used in radioisotope thermoelectric generators, where the heat of its radioactive decay is converted to electricity for long-lived, lightweight power sources in navigation buoys, remote weather stations, and space vehicles.
Noisy and erratic valve operation can be eliminated with entirely mechanical valve-lifter linkage only if the tappet clearance between the rocker arms and the valve stems is closely maintained at the specified value for the engine as measured with a thickness gauge.
