  • Page 4: Safety Instructions

    General dangers due to non–observance of the safety instructions The U3 force transducer corresponds to the state of the art and is fail–safe. The transducers can give rise to residual dangers if they are inappropriately installed and operated by untrained personnel.
  • Page 5 Meaning: CE mark The CE mark signals a guarantee by the manufacturer that his product meets the requirements of the relevant EC directives (see Declaration of conformity at the end of this Mounting Instructions).

  • Page 6 Protect the transducer from damp and weather influences such as rain, snow, etc. Maintenance The U3 force transducer is maintenance free. Accident prevention Although the specified nominal force in the destructive range is several times the full scale value, the relevant accident prevention regulations from the trade associations must be taken into consideration.

  • Page 7: Scope Of Supply

    100kN Order no. 1–Z4/100kN/ZGUW Application information Force transducers of the U3 type series are suitable for measuring tensile and compressive forces. They measure static and dynamic forces extremely accurately and therefore require careful handling. You must take particular care when transporting and installing the devices. If you knock or drop the transducers, this could permanently damage them.

    50mm stranded copper wire (highly flexible signal ground cable EEK from the HBM line). The cable is attached by screws both above and below the transducer. This prevents welding current flowing over the transducer and welding the force introduction point.

  • Page 12: Installation For Tensile Loading/Compressive Loading

    12.9 DIN912 galvanized HBM supplies knuckle eyes as mounting accessories for transducers of the U3 type series. Knuckle eyes are suitable for use during quasi–static loading (10Hz alternating loads). In the case of dynamic loading at a higher frequency, you should use flexible tension bars. Knuckle eyes prevent the introduction of torsional moments and when 2 knuckle eyes are used, stop bending moments and transverse and angular loading being introduced in the transducers.

    1000 M10x25 Attaching the knuckle eye: • Screw the correct adapter (dependent on nominal force!) to the U3 (please note screw length, screw quality A2–70, at 100kN. 12.9 DIN912, galvanized) • Turn the lock nut back as far as the eye •...

    M10x25 M10x30 Attaching the knuckle eye: • Screw the correct adapter (dependent on nominal force!) to the U3 (please note screw length) • Turn the lock nut back as far as the eye • Screw the knuckle eye into the adapter as far as the stop ATTENTION Do not apply force to the transducer flange.
