Torque Measuring Flanges with Approval for Ships

MANNER has expanded its portfolio of torque measuring flanges to cover higher measuring ranges. The tried and tested design of the short torque measuring flange is now also available for measuring ranges above 1,000 kNm. The flange is characterized by a compact form offering high overload resistance. This technology is useful in many areas of application, and for years has proved to be of particular value in the shipbuilding industry. Through the use of our digital sensor telemetry, acquiring the measurement signals from the rotor is a straightforward process. Typical 10 mm radial clearances between rotor and stator and axial displacement paths of 100 mm can be realized easily.

Another option is the non-contact measurement of the speed signal by means of ring gear and sensor. This robust design has been proven in practice.

Particularly noteworthy is the extended network capability in our products. In addition to the available network connections USB, CAN and Ethernet (TCP/IP), we now provide EtherCAT connections to help integrate the torque sensor seamlessly into existing EtherCAT networks. EtherCAT technology offers enormous advantages in particular with large test rigs. The real-time protocol allows control processes for torque-controlled drives. The standard version of MANNER torque measurement technology delivers 6,700 readings/second. The decoupled acquisition and bus processes mean that the user is free to select a sampling frequency in the EtherCAT bus system. The use of the Ethernet hardware platform gives the option of using fibre-optic cables, which support large transmission distances of several kilometres and ensure a completely interference-free transmission of the measured values – even under harsh EMC conditions.

Utilizing digital sensor telemetry helped to further optimize system accuracy for hysteresis and linearity and improve on the 0.05% results. With this sensor generation, the torque values are already digitized in the rotor with 16 bits. For extremely high-precision applications, the torque values are acquired in the rotor with a 24 bit resolution. This makes MANNER the first provider to offer such high resolution at maximum accuracy for rotating torque sensors.
