Delivery: ex stock/3 weeks | Warranty: 24 months Metal Bellows Coupling MODEL 8690 Highlights Rated torques from 0 ... ±0,5 N·m to 0 ... ± 200 N·m Adaptation to the required shaft diameter Accurate transmission of angle and torque Suitable for dynamic and static application Options Keyways Finely balanced version Applications Simple assembly and safe integration of torque sensors Compensation of shaft diameter Product description Even after careful alignment of the shaft ends of the sensors with the shaft ends of the plant; slight axial, angular or lateral shift must be anticipated. These interfere with the measurement and can lead to damage on the sensor in the event of high speeds. Rated torque ≥ 2 N·m The 8690-type steel bellow coupling is fastened, using a clamping hub per torque transmission, to the sensor and plant shafts. The facility-side bore is adapted to the existing shaft diameter, which means that the torque sensor can be mechanically integrated without further adaptations. A stainless steel bellow transmits the torque between the clamping hubs without backlash. Through its highly elastic but stiff material properties, a lossless transfer of the torque transmission is guaranteed. Axial, angular and lateral shifts caused by assembly and construction are effectively compensated. burster Sensors and Process Instruments – Technical changes reserved. All data sheets at www.burs

Dimensional drawing Model 8690 For detailed dimensions, you can find the CAD data of the sensor on our website www.burster.de Mounting The couplings have two different attachment systems: To rated torque 0.5 N·m: The coupling has two radial set screws (ISO 4029). The screws are forming an angle of 120°. The screws are arranged at an angle of 120° to each other and press directly on the shaft. With integrated disassembly nut. Mounting instructions From rated torque 1 N·m: The connection between the shaft and coupling is made with a clamping hub. Only one radially arranged clamping screw (ISO...
