1 Applications
The SLB700A strain transducer measures static and dynamic strains or
upsets to steel structures.
The application concentrates on monitoring functions on cranes, containers,
bridges, presses, roll stands and similar structures. Simply attached by four
screws, the SLB700A can also be subsequently fitted to existing structures.
2 Principle of measurement
The four screws maintain a solid connection between the SLB700A strain
transducer and the measurement object. Mechanical loading produces a
change of length in the measurement object, which is conveyed to the
SLB700A. Because there is a change in length, the electrical resistance of the
applied strain gauge also changes in proportion to the strain. If there is
excitation voltage, the circuit supplies an output signal proportional to the
change in resistance and therefore also proportional to the change in length.
A carrier frequency or DC amplifier suitable for strain gauges enables
measurement signal evaluation to continue.
3 Mounting
The SLB700A strain transducer is attached to the measurement object by
means of four normal M6 hexagon socket screws (e.g. DIN 912). We
recommend screws of resistance class 12.9, which should be tightened in a
sequence of diagonal opposites, using a tightening torque of 16 N
⋅
m.
Alternatively, use screws of resistance class 8.8 and a tightening torque of
8 N ⋅ m. The strain transducer must not be mounted in the central, offset area
and it must be installed free from distortion.
