Compact strain transducer

July 2009 Operator Interfaces, Switches & Relays

HBM has introduced the 6 mm high SLB-700A strain transducer to measure strains on solid components, such as cranes and bridges, where high loads need to be measured. The compact size of the strain transducer allows it to be easily mounted on any component with standard M6 hexagon socket screws. The SLB-700A has a measuring range of 500 μm/m, and provides a high safety reserve with a breaking strain of 300%.

The 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 that is proportional to the change in length.

The SLB-700A’s housing is made of stainless steel and meets IP65 to protect the strain transducer against environmental influences. It can also be used under the harsh ambient conditions found in industry.

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