HFM Series Moleculoy® Alloy wire strain gages provide a “no shelf life” alternative for
elevated temperature dynamic strain gage requirements. Moleculoy is a non-magnetic
75/20-nickel omium alloy modified with cobalt and aluminum. The flattened and
heat-treated Moleculoy grid eliminates the need for a grid carrier during storage,
virtually eliminating shelf life. The standard omel leads are installed inboard. This
feature combined with a narrow pitch reduces grid size to a minimum. Convoluted leads
also available.

high-temperature weldable strain gages are free-filament wire

strain gages pre-bonded to shim
stock using flame sprayed alumina. The gages can be
welded to the test structure using a capacitive disge spot
welder (such as Micro-Measurements Model 700), permitting
easy installation in the field, especially on large structures.
High-temperature weldable strain gages are excellent in
applications protection against moisture is not
required. The fatigue resistance of this bonded wire strain
gage makes it the best choice for dynamic, impact or
vibratory strain measurements to 1800°F [980°C]. Their use
in measuring static strains should be avoided.
High-temperature weldable strain gages are available with
grids of Niome V or Pt8W alloys. They can be ordered
with either of two types of preattached high-temperature
insulated cable.

Complete assembly consists of a free-filament gage bonded
to a shim with an integral high-temperature cable with
omel/alumel wires. The mineral insulated, two-conductor
cable with an Inconel metal jacket is rated to 1800°F [980°C]
and offers excellent protection in harsh environments. While
the ends are sealed to avoid moisture absorption during
shipping or storage, care should be taken when using
M-Series cables to ensure that the mineral insulation does
not absorb moisture during handling and application.
Complete assembly consists of a free-filament gage bonded
to a shim, a weldable transition terminal and a high
temperature cable with omel/alumel wire. A fiberglass-
insulated braided, two-conductor cable assembly is attached
at the gage end through alumina insulators strap-welded to
the terminal shim, providing a firm anchor for the cable at the
gage end. The cable conductors are threaded through
lengthwise holes in the alumina insulators and bonded to the
insulators with high strength ceramic cement to prevent wire
movement at the gage - cable weld junction. The fiberglass
cable is rated to 1200°F [650°C] and is used fraying
due to vibration is not a concern. F-Series cables are more
flexible than M-Series cables.
