The following symbols are used in this operation manual to warn of hazards. Symbols used in the operating manual 1.1.1 Signal words The following signal words are used in the operating manual according to the specified hazard classification. DANGER High degree of risk: indicates a hazardous situation which, if not avoided, will result in death or serious injury. WARNING Moderate degree of risk: indicates a hazardous situation which, if not avoided, may result in death or serious injury. CAUTION Low degree of risk: indicates a hazardous situation which, if not avoided, could result in minor or...

IMPORTANT: Read the operating manual carefully before using the equipment, and keep for future reference. The load cells in the 8561 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. 2.1.1 Customer service department For repair inquiries, please call our customer service department on +49 7224 645-53. Please have the serial number to hand. The serial number is essential to establishing the definite technical...

2.3.1 Storage The model 8561 2-axis load cell must be stored under the following conditions: • dry • no condensation • temperature between 0 °C and 60 °C Note: 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 8561 2-axis 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 8561 2-axis load cell for full details of dimensions, weight, degree of protection etc. Mechanical design The model 8561 2-axis load cell consists of two spring elements in the form of bending beams, which are joined to the central part. Strain gages X/Y measuring elements with strain gages applied A radial force in the central part of the load cell deforms these measuring elements, causing a displacement of the measuring axis. The resulting elongation is not visible to the naked eye and is measured using strain gages....

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, in the model 8561 2-axis load cell four strain gages are connected as a Wheatstone bridge for each measurement direction. Figure 3 illustrates this wiring in a simplified form. Full-bridge strain gage on the model 8561 2-axis load cell for one measurement direction To reduce the effect of temperature, modulus-compensation strain gages are used. In addition to the four strain gages shown...

External forces External forces here refers to any force that does not act radially to the sensor’s axis of symmetry – particularly transverse forces, bending moments and torsional forces. NOTICE Damage to the model 8561 2-axis 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. IMPORTANT: External forces acting on the model 8561 2-axis load cell will significantly falsify the measurement result!

Using the instrument for the first time CAUTION Never switch on the model 8561 2-axis load cell if it shows signs of damage incurred in transit. Only ever use the model 8561 2-axis load cell under the conditions specified in this operating manual. NOTICE Only connect the model 8561 2-axis 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 signal lines of the model 8561 2-axis load cell must also be fitted with safety transformers to EN 61558.
