Dual-range model for measuring start-up and continuous operation characteristics

• Dual-range model
• Ratio 1:10
• High precision for both measurement ranges
• Scaled standard signal output for both measurement ranges
• No downtimes for sensor replacement
• Cost savings

Task

In order to improve the electromechanical energy conversion in geared motors in different load scenarios with a view to long operation lives, it is essential to measure mechanical, electrical and thermal characteristics in endurance testing.

Specific requirement

During the start-up phase under load, disproportionately high starting torques often arise that lie well above the steady-state load torque.

Solution

The dual-range model can be used to measure precisely and reliably the starting torque in the first measurement phase and the steady-state load torque in the second phase. The change to the second measurement range is made by applying a signal level to the switchover channel.
