Interface transmits torque and speed signals via fieldbus system

The recently upgraded TIM-EC interface, developed to transmit torque and speed signals digitally via the EtherCAT fieldbus system is now available from HBM.

Designed to enhance performance and the field of applications in field bus automation and control systems, such as in test benches for electric motors, combustion engines, gears, pumps and compressors, the recently enhanced module also permits the use of simulation models for performing early tests in the test bench before a prototype is available.

The advanced TIM-EC module provides accurate and fast data transmission with low delay times. In addition to providing angle of rotation and power output data, the most recent module also provides torque and rotational speed signal on the module’s backplane bus.

The TIM-EC module supports a sampling rate of up to 20,000 measured values per second on the bus and is characterised by a low group delay of approximately 100µs. Signals are transmitted digitally and without loss of accuracy and both the angle of rotation and the performance can also be captured.

The module also features an integrated coupler functionality or TIM-to-TIM communication that facilitates the integration of the torque transducer into independent industrial Ethernet networks, so that measured values can be independently adapted to the respective measurement task.  This opens up possibilities for high-precision control and analysis of measurement series, particularly for dynamic tests.
