Installing Gages With Option P

Protective Coatings

Option P provides electrical insulation of the gage grids, solder joints, and conductors on the gaged end of the cable. Nevertheless, an additional protective coating is recommended when the gage installation is exposed to moisture, chemical attack, or potential for mechanical damage. When applying coatings, pay particular attention to the junction between the jumper and cable leadwires. The vinyl insulation covering this connection does not provide a waterproof barrier. Apply an appropriate coating in this area before the cable is permanently anchored to the specimen.
