This operation manual is intended to help familiarize you with the device and obtain the full functional benefit from its capabilities. The operation manual contains important information for the safe, proper and effective use of the device. Follow the instructions carefully to reduce repair costs and downtime, and to increase the reliability and service life of the device. This operation manual applies exclusively to the model 8565 load cell and torque sensor (henceforth: “sensor”). This operation manual is intended for personnel who install and operate the sensor. To enable you to work quickly...

Conversions and modifications Note: The warranty shall be deemed void immediately if you open or dismantle the sensor during the warranty period. The sensor does not contain any parts that are intended to be serviced by the user. Only the manufacturer’s own qualified personnel are permitted to open the sensor. It is not permitted to make any changes to the sensor without the written agreement of burster präzisionsmesstechnik gmbh & co kg. burster präzisionsmesstechnik gmbh & co kg does not accept liability for damages or injury if this condition is disregarded.

IMPORTANT: Read the operation manual carefully before using the device, and keep it for future reference. 2.1 Applications2.1.1 Intended use The sensor is intended mainly for force/torque measurements in production facilities, units newtons (N) and newtonmeters (Nm). The local acceleration due to gravity (g = 9.81 m/s2) must be taken into account when determining masses. 2.1.2 Restrictions on use The sensor does not pose a hazard if used within its specification and in accordance with safety regulations. The manufacturer does not accept liability for any personal injury or property damage arising...

Load Cell/Torque Sensor - X/Y/Z 85653 Description of the sensor Please refer to the sensor’s data sheet for full details of dimensions, weight, degree of protection etc. (see section 15). The sensor has an internal structure which, under deformation, allows forces and torques to be measured by means of strain gages and converted into an electrical signal. 2 Contact surfaces for force transmission (4x) (robot flange conforms to DIN ISO 9409-1) (robot flange conforms to DIN ISO 9409-1)

Requirements for accurate measured values Full-scale deflection The applied forces and torques deform the sensor by approx. 15 µm to 40 µm, depending on the load direction. This deformation is known as the “full-scale deflection”, and is so small that it cannot be seen with the naked eye. Crosstalk means the mutual influence of the individual channels on each other. If one component is loaded, the other channels show a very small, unwanted signal. It is only possible to specify the crosstalk if the sensor measures several components (forces Fx, Fy, Fz or torques Mx, My, Mz). The quality of the...

Planning the desired application Calculating the maximum load The maximum limit value (Lmax) must not be exceeded with dynamic loads. The formula for calculating Lmax can be found in the data sheet (see section 15). Use the formula to add up the maximum occurring force and torque vectors with a weighting factor. The calculated value for Lmax must remain smaller than the value specified in the data sheet. Please note that the sensor’s coordinate origin is located at the geometric center of the sensor. When calculating the maximum operational force, the additional bending moments due to leverage...

The maximum occurring forces and torques depend on the weight and shape of attached parts, as well as their orientation during acceleration. Contact surfaces A high quality measurement depends on a defined deformation of the measuring element under load. To prevent unwanted deformations, the upper and lower contact surfaces of the sensor (see section 3.2) must rest on the mounting surface. The mounting surface must meet the following requirements: • adequately stable • hardened, minimum hardness 60 HRC • ground, preferably lapped, surface quality: Ra < 0.8, evenness 10 pm • must contain no holes...

Load Cell/Torque Sensor - X/Y/Z 85655 Unpacking / contents of pack / storage5.1 Unpacking ► Never connect the sensor if it shows signs of damage incurred in transit. ► Only ever use sensor under the conditions specified in this operation manual. ► Inspect the sensor for damage. If you suspect that the unit has been damaged during shipping, notify the delivery company within 72 hours. The packaging should be retained by a representative of the manufacturer and/or the delivery company. The sensor should be transported only in its original packaging or in packaging capable of providing an equivalent...

Load Cell/Torque Sensor - X/Y/Z 85656 Installation6.1 Fixing method6.1.1 Requirements for fitting Screws ► Use only screws with the properties specified in the data sheet (see section 15). Mounting surfaces ► Make sure that all mounting surfaces meet the requirements described in section 4.3. 6.1.2 Fastening the sensor We recommend centering the sensor via the inner centering surface 046 H7. The inner centering surface is only intended for centering via the sides. Any transmission of force via the end faces must be avoided. ► When centering, make sure that the mating part does not completely...
