The version with a second measuring range (optional) is ideal for applications with a high peak torque but moderate operating torque. A torque sensor with only one measuring range would have to be chosen to withstand the peak torque. As a result it would, however, be oversized for measuring the oper ating torque actually of interest.
The dual range sensor offers the advantage of range switch ing, which allows highly accurate measurement of both the peak and particularly the operating torque.
Power is supplied and the measurement signals transferred between the rotating shaft and the case without contact. In addition to suitable mounting of the shaft, low production tol erances and high grade balancing, this is a further prerequisite for the high speed limit of up to 50 000 1/min achieved with the "H" version.
