LF: Miniature Linear strain gauges with 1 measuring grid

With the LF miniature strain gauges we offer you suitable strain gauges for measurements on small components like printed circuit boards or other applications with limited space available. 

Compact

  • The smallest variant is only 2.3 mm wide and 2.9 mm long

Easy handling

  • Various connection options
    • Pre-wired with color-coded, enameled copper wires, 0.5 m wire length in a 2-wire configuration
    • High flexibility due to extra thin carrier

No soldering on the strain gauge required

Available for immediate delivery

  • Standard versions available from stock

Save time and start straight away!

 

The high-quality, reliable, and flexible strain gauges for experimental stress analysis can be combined perfectly with HBK's DAQ amplifier QuantumX and catman DAQ software for a complete measuring and testing solution. From the sensor to the software: simply "plug and measure".
