Manner torque measuring flange now available with EtherCAT connection

Manner Sensortelemetrie seamlessly integrated into existing EtherCAT networks. EtherCAT technology offers huge advantages, particularly with larger test facilities. The real time protocol allows control processes for torque-guided drives. In its standard version, Manner’s torque measurement technology provides 6,700 readings per second. Decoupling the recording and bus processes allows the user to select the sampling frequency in the EtherCAT bus system. With the Ethernet hardware platform fibre optic cables can also be used. Large transmission distances of several kilometres are possible with guaranteed absolutely interference-free transmission of the measurements – even under harsh EMC conditions.

The rotation speed data collected using the integrated speed measurement system is also transmitted. The classical data recording interface is no longer needed which greatly cuts costs. In fact, the measuring flange, together with a PC represents a plug-and-play data acquisition system. The software needed to visualise the readings is also provided.

Using digital sensor telemetry, the system accuracy for hysteresis and linearity has been improved to better than 0.05%. With the new generation of sensors, the torque values are already digitised in the rotor with 16-bit resolution. For extremely high-precision applications the torque values can be recorded with 24-bit resolution in the rotor. Thus Manner is the first supplier to offer such high resolution and high accuracy for rotary torque meters.

The large distance between the rotor and stator, the compact pick-up and the robust design, not only guarantee easy fitting but have also proved themselves in practice. Of course, classic analogue output signals can also still be provided.
