  • High Temperature Use Strain Gauge ZF series

ZF series High temperature use strain gaugeCE

These strain gauges are designed for measurement in high temperature up to 300℃. It utilizes specially designed Ni-Cr alloy foil for the grid and polyimide resin for the gauge backing. Owing to the construction, the strain gauges are successfully used for measurement in high temperature.

    Each package contains 10 gauges.
    *We can also make self temperature compensated strain gauges suited to materials where the coefficient of thermal expansion is other than 11×10-6/℃ (made-to-order).
    Example material: stainless steel, aluminum alloy
