Gauges on membranes

GAUGES ON MEMBRANES

High quality, miniaturized, semiconductor strain gauges – measures nano-strain!

Single gauge or multiple gauges on membrane; strain gauge bridges on membrane (half & full), with or without wires.

Innovative semi-flexible material that allows an easier application to the deforming surface. Reduced dimensions make it ideal for applications with reduced space.

Technical characteristics

Wide portfolio of high quality semiconductor strain gauges in various shapes (“Bar“, “U“, and “M“) or any other customized configuration.

Size as small as 0.4 mm to 6 mm. Gauge Factors (K): 100 – 200.

Resistance: 15 Ω – 50 k Ω. Ideal for wireless applications.

Advantages

Extreme sensitivity: 10-9 strain resolution
