Precise measurement of forces

October 2010 Sensors & Transducers

High-precision measurement of compressive and tensile forces is possible with the S9M force transducer from HBM. The transducer works with strain gauges (SG) and the S-type geometry gives an accuracy class of 0,02, which is an improvement on its predecessor the S9, which had an accuracy class of 0,05. Compensation for parasitic influences, such as lateral forces or bending moments is excellent, and measurement reliability improves accordingly. The transducer is also insensitive to the effects of temperature and temperature gradients. The S9M is available with different nominal (rated) force ranges, from 500 N to 50 kN.

The strain gauges are hermetically integrated into the measuring body for safe protection. The stainless steel housing provides protection to IP68 for use in adverse ambient conditions. Mechanically, the transducer is fully compatible with its predecessor the S9 so there is no problem with compatibility of accessories and the older model can easily be replaced with the new S9M.
