High Temperature Use Strain Gauge EF Series

These gauges have a small grid pattern required for measurement of printed circuit boards and surface mounted devices, which are getting smaller and smaller. The backing of the gauges is made of polyimide resin. The maximum operaing temperature is +300℃ for single element gauges and +200℃ for two and three elements gauges. The lowest operating temperature is -196℃ for both gauges.
