On the torque sensor model 8661 and in this manual the following symbols warn about risks. 1.1 Symbols in this manual The following signal words are used in the operation manual according to the specified hazard classification. DANGER DANGER indicates a hazard with a high level of risk which, if not avoided, will result in death or serious injury. WARNING indicates a hazard with a medium level of risk which, if not avoided, could result in death or serious injury. CAUTION indicates a hazard with a low level or risk which, if not avoided, could result in minor or moderate injury. Property damage...

General safety instructions The torque sensor model 8661 uses state-of-the-art engineering and is safe to operate. However, if the torque sensor model 8661 is not used or operated as intended, it may present a hazard. DANGER Danger of electric shock! The following instructions must be followed to prevent electric shock and injuries: • In order to achieve high measuring characteristic value, the torque sensor model 8661 is not designed with the usual safety factors (2…20) for machine designs. For applicable overload factors, see the technical data (data sheet). • Observe accident prevention regulations,...

IMPORTANT: Read the operation manual carefully before using the equipment, and keep for future reference. The torque sensor model 8661 measures static and dynamic torques on rotating or stationary machine parts in either direction of rotation. You have the option of measuring rotational speed or angular displacement. The respective upper range value is shown on the type plate. The USB version of the 8661 torque sensor model 8661 transmits all measurement signals via USB. Both the low mass of the torque sensor model 8661 and its high torsional rigidity are an advantage when measuring dynamic torques....

2.3 Environmental conditions • Avoid radiant heat or cooling from one side. • Protect the torque sensor model 8661 from moisture. • The torque sensor model 8661 is not resistant to the effects of chemicals. Do not use the torque sensor model 8661 in a corrosive environment. • Keep the bearings and connectors free of dust, dirt and other foreign matter. Use clean packaging to package the torque sensor model 8661. The torque sensor model 8661 must be stored under the following conditions: A DANGER Electric shock hazard! Disconnect the torque sensor model 8661 from the electrical supply before cleaning....

• Torque sensor model 8661 • Mating connector • Operation manual • Data sheet DANGER Electric shock hazard! Never connect up the torque sensor model 8661 if it shows signs of damage incurred in transit. Only ever use the torque sensor model 8661 under the conditions specified in this operation manual. Inspect the torque sensor model 8661 carefully for damage. If you suspect that the torque sensor model 8661 has been damaged during shipping, notify the delivery company within 72 hours. The packaging should be retained for examination by a representative of the manufacturer and/or the delivery...

2.8 Conversions and modifications Note: If you open or dismantle the torque sensor model 8661 during the warranty period, this will void The torque sensor model 8661 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 torque sensor model 8661. It is forbidden to make any modification to the torque sensor model 8661 without our written permission. We cannot accept liability in the event of such action. • Check the bearings at least once a year to see that they still move freely. • Replace the special...

Test side The test side is that end of the shaft at which you apply the torque being measured to the torque sensor model 8661. This side normally has the smallest moment of inertia. Torque sensors model 8661 with measuring ranges up to 2 Nm have a smaller and therefore lower-friction ball bearing fitted at this end. You will see these markings on the measurement end of the torque sensor model 8661: Test side Drive side The drive side is the opposite end to the measurement end. The torque sensor model 8661 is also mechanically connected at this side. This side normally has the larger moment of...

You can use the torque sensor model 8661 to measure both clockwise and counterclockwise torques. If the torque is exerted in an anticlockwise direction (looking at the measurement end), you will get a negative signal at the output. Torque, anticlockwise (looking at measurement end) Sign convention for measuring angular displacement If the sensor shaft rotates clockwise (looking at the drive end), channel A leads channel B by 90°. If the sensor shaft rotates anticlockwise (looking at the drive end), channel B leads channel A by 90°. Static and quasi-static torques Static and quasi-static torques...
