Low degree of risk: indicates a hazardous situation which, if not avoided, could result in minor or...

Tension and Compression Load Cell 84272 IntroductionWICHTIG: Read the operation manual carefully before using the equipment, and keep it for future reference.2.1 Intended use The load cells in the 8427 model series are primarily designed for the measurement of force in production equipment, using newtons (N) as the unit of measurement. The local gravitational acceleration (g = 9.81 m/s2) must be taken into account when determining masses. Customer service 2.1.1 Customer service department For repair inquiries, please call our customer service department on +49 7224 645-53. Please have the serial...

Tension and Compression Load Cell 8427 The model 8427 tension and compression load cell must be stored under the following conditions: Hinweis: Provided the storage conditions have been observed, no special steps need to be taken after storage and prior to commissioning. NOTICE Only connect the model 8427 tension and compression load cell to instrumentation amplifiers that are fitted with a safety transformer to EN 61558. Transmitters connected to the outputs or other devices that are galvanically connected to the sensor’s signal lines must also be fitted with safety transformers to EN 61558....

Concept and general information Please refer to the data sheet for the model 8427 precision tension and compression load cell for full details of dimensions, weight, degree of protection etc. Mechanical design In the model 8427 tension and compression load cell, the spring element is designed as a horizontally oriented elastic membrane with a centrally arranged ring. Horizontally oriented membrane This elastic membrane is deflected by the applied force, resulting in a reduction in the height of the sensor. This deformation cannot be seen by the naked eye. It is measured with the aid of strain...

Foil strain gage Special techniques are used to mount strain gages manufactured in this way onto the surface of the spring element. Strain gage wiring In order to reduce undesirable influences on the measurement, the strain gages in model 8427 tension and compression load cells are connected as a Wheatstone bridge. Figure 3 illustrates this wiring in a simplified form. Full-bridge strain gage for model 8427 tension and compression load cells In addition to the four strain gages shown here, compensation resistors to reduce the effect of temperature and balancing resistors to balance the bridge...

External forces External forces here refers to any force that acts outside the sensor’s axis of symmetry – particularly transverse forces, bending moments and torsional forces. NOTICE Damage to the model 8427 tension and compression load cell Avoid vibrations, even if the generated loads remain below the rated load, and avoid external forces acting on the load cell. Design your measuring system in such a way as to prevent these external forces. WICHTIG: External forces acting on the model 8427 tension and compression load cell will significantly falsify the measurement result! Using the device...
