Sherwin: PSM-5 Penetrant System Monitor Panel
Penetrant System Monitor Panel
Sherwin PSM-5 Penetrant System Monitor Panel:
A stainless steel panel, 0.090" thick and measuring 4 x 6 inches. A chrome plated strip runs the length of one side of the panel. Five crack centers are evenly spaced in the chrome plating in order of magnitude; the largest is readily visible with low sensitivity penetrants, while the smallest is difficult to observe even with high sensitivity materials. Adjacent to the chrome plated section is a grit blasted area of "medium roughness" to judge penetrant wash characteristics.
The PSM-5 Panel comes in two versions. Both versions are manufactured to Pratt-Whitney P/N TAM 146040 specifications.
Grit Blasted Type - has a chrome strip which has been lightly grit blasted in order to dull the surface.
Smooth Type - the chrome plated strip of the second version is not grit blasted.
Sherwin Incorporated is an authorized manufacturer of TAM 146040 panels.
PSM-5 Panel processing meets MIL-STD-6866 and ASTM E-1417 requirements for daily system check.
