| The SLB700A strain transducer from HBM attaches directly to a plane surface with a friction joint ａnd four bolts. This arrangement enables the strain of the test object to be transferred directly to the SLB700A making it ideal for installations where lack of space, or installation conditions, makes it difficult to use standard force transducers. Ideal applications for the stainless steel SLB700A include multi-stand ａnd C-stand presses. The strain transducer is mainly intended for applications where high forces are to be measured such as roll stands ａnd injection molding machines. Where bending effects need to be compensated, at least two SLB700A strain transducers should be mounted on opposite sides of the test piece ａnd connected electrically in parallel.

HBM SLB700A - 高應力應變傳感器
The SLB700A strain transducer from HBM attaches directly to a plane surface with a friction joint ａnd four bolts. This arrangement enables the strain of the test object to be transferred directly to the SLB700A making it ideal for installations where lack of space, or installation conditions, makes it difficult to use standard force transducers.
Ideal applications for the stainless steel SLB700A include multi-stand ａnd C-stand presses. The strain transducer is mainly intended for applications where high forces are to be measured such as roll stands ａnd injection molding machines.
Where bending effects need to be compensated, at least two SLB700A strain transducers should be mounted on opposite sides of the test piece ａnd connected electrically in parallel.
Reliable measurement resultsThe SLB700A is designed with compensating elements for adapting to the different steel types commonly used in mechanical engineering. The feature means that the temperature effect that could lead to major zero offsets can be neglected. Without the compensating elements, the different thermal expansion coefficients of transducer ａnd test object would change the transducer’s zero signal.
The SLB700A features a high degree of protection ａnd comes supplied with an oil-resistant cable.
Easy integration into automation systemsThe PME ａnd digiCLIP amplifier systems complete the SLB700A ａnd provide a self-sustained monitoring unit for all industry requirements. The complete system features a CAN or Profibus interface for easy integration into automation systems.
- For monitoring strain in statically ａnd dynamically loaded units such as cranes, presses ａnd roll stands
- Simply bolted into place
- Stainless steel
