Strain gauge incorporates solder tabs and strain relief

Any resistance variations at the strain gauge connection points are compensated by the four-wire configuration. The temperature response of the strain gauges is matched to either ferritic steel or aluminium in a temperature range of ""200 to +250degC.

The strain gauge is available in standard measuring grid lengths of 3mm and 6mm, with a resistance of 350ohms. Different configurations of measuring grid length, resistance, and type are available on request.

HBM says the LC61-3/350 significantly reduces the installation time in extreme temperature ranges (-269 to +250degC). This is because it replaces the metal foil strain gauges based on chrome-nickel alloy that are often used for these applications and take longer to connect.
