EFRA Series High Temperature Use Strain Gauges
3-element stacked 0°/45°/90° miniature composite material high temperature strain gages
About the EFRA Series High Temperature Use Straingauges
EF series High temperature use strain gauge
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 operating temperature is +300°C for single element gauges and +200°C for dual and 3-element gauges. The lowest operating temperature is ‒196°C for both gauges.
Features EFRA
- Type: Miniature high temperature stacked 3-element, for metal and composite material
- Gauge resistance: 120Ω
- Gauge length: 0.5mm
- Gauge width: 0.4mm
