General information
Bondable high temperature gages are intended for measurements of deformations in the details of machinery and equipment, including jet engines and gas turbines, under static and dynamic loads in -269…+1150°C temperature range. Strain gage can be produced of NiCr, FrCrAl or PtW alloys and fixed with the temporary carrier, of fiberglass-reinforced PTFE.
Schematic drawing
Measurement of stress-strain parameters of machine parts is the most important task in ensuring their strength and reliability. To measure the deformation of parts, strain gages — resistors whose resistance changes depending on its deformation (stretching or compression) — are widely used. Strain gages are used both for measuring the deformation of various parts for research and testing purposes and as part of various sensors: force or weight, pressure, displacement, torque.
Designation system
Packaging
Individual strain gages are supplied on plastic or glass carriers, can be covered with protective plastic foil. Each strain gage is labelled with the actual electric resistance values. Groups of strain gages are packed in plastic boxes in amount of 1...25 pieces. Each group packing has a label with the main parameters of the gages, including resistance range of the gages group, gage factor, production date, etc. Batches of strain gages are packed in plastic containers with or without auxiliary installation tools. Each batch container has a label with all main parameters of the gages, general description, batch number and production date.
