Torque Measuring Flange

MANNER has developed a special, compact measuring flange with an integrated overload protection mechanism for drive trains. The overload protection allows an overload factor of 100. The destruction of the torque sensor during overload can therefore be prevented. This risk arises during a sudden blocking of the drive train (bearing damage). Another application case is the measurement of the smallest torque on an over-sized drive train. High breakaway torques are therefore no longer a problem. The overload protection also serves as fitting protection, particularly for smaller torque sensors (T <20 Nm). Here, the sensor can already be damaged by the tightening force of the screws. The measuring flanges operate without bearings. The system accuracy could be improved to 0.05% for hysteresis and linearity through introduction of the digital sensor telemetry. The torque values are already digitalised in the rotor with 16 Bit. The speed signal is also recorded without contact using a gear rim and HALL sensor. This robust design has already proven itself in practice. Ethernet, USB-bus and CAN-bus for connection to control are also available. In addition, the classical analogue output signal is also on offer.
