HBK - Hottinger Brüel & Kjaer (Germany) - Press Release: Cost-efficient force and mass measurement. The SLH700 strain transducer can endure rough environments, for example in silo weighing or structural monitoring tasks. Other typical applications are press monitoring, welding force measurements or force measurements in c frames.
Strain transducer SLH700 – Hermetically sealed and with minimal influence on the measured object allowing use for lower strain to force comparatives.
Extensometers, such as the SLH700 series measure forces indirectly and are distinguished by their simple yet effective functionality. When a force is applied to the structure on which the sensor is mounted, deformations whose magnitude depends on the applied force, occur. Therefore, even large forces can be measured with economically once the SLH700 has been calibrated.
SLH700 strain links are made from stainless steel materials, are hermetically sealed and have a high degree of protection (IP68). Their cable is resistant to most oils and many other potentially aggressive fluids. The transducer is built as a strain transformer. Therefore, the output signal is six times that of the single strain gauge.
The SLH700 strain link series can be purchased with or without an integrated amplifier, providing a selection of analogue output signals. All variants have an extremely low force shunt and can easily be mounted, requiring only two standard M6 screws.
- HBM accuracy class: 0.5
- Nominal (rated) measurement ranges: 150 µm/m
- Outputs: 1,5 mV/V, 0... 10 V, or 4... 20 mA, depending on variant
