Compact strain transducer features high safety reserve

Paul Boughton
HBM is introducing the 6mm high SLB-700A strain transducer to measure strains on solid components, such as cranes and bridges, where high loads need to be measured. Its compact size means the strain transducer can easily be mounted on any component with standard M6 hexagon socket screws. The SLB-700A has a measuring range of 500 um/m and provides a high safety reserve with a breaking strain of 300 per cent.

Strain is transmitted through the connection with the component to the strain transducer. The change in length is transmitted in the strain transducer to an integrated strain gauge, which supplies an output signal through an appropriate circuit that is proportional to the change in length.

The SLB-700A's housing is made of stainless steel and is protected to IP65. It can also be used under harsh ambient conditions, such as in industrial applications.

Typical applications for the strain transducer are large machines and steel structures such as cranes and bridges, as well as press fitting, punching or rolling machines.
