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
