Speed measuring system has high
resolution
A robust magnetic speed measuring system, for use with torque flanges, enables the simultaneous recording of torque and rotational speed at high resolutions.
HBM has introduced a robust magnetic speed measuring system enabling the simultaneous recording of torque and rotational speed at high resolutions for its T10FS torque flange The speed measuring system is based on the non-contact sampling of a magnetized rotor by means of magneto-resistor sensors

Amplifier increases press-fit assembly accuracy
A measurement amplifier simplifies two-channel manufacturing and testing processes, such as press-fit monitoring, to ensure greater fitting accuracy.
Measurement consistency improved for torque
Improvements made to torque measurement equipment enable all SG full bridge amplifiers to be used for torque measurement and measurement shafts also benefit from a rotational measuring system.
Two half bridges, aligned at 90 degrees to each other, generate the angle-dependent analog signals.
Since the signals are absolute and adequate pulse stability is given even when stopped, the system can also be used for measuring angles of rotation.
The magnetic speed measuring system meets the high requirements demanded during power measurement when combined with torque flanges.
Depending on the nominal measuring range and other selected factors, an output pulse count of up to 1,800 pulses per revolution may be possible.
The number of electrical pulses is easily altered allowing the system to be coordinated with any electronics.
Integration of the system into the transducer simplifies handling and eliminates the connection problems of conventional speed transducers that, for example, use straps.
The large permissible radial working distance of between 0.3 and 2.2mm, depending on the measuring range, combined with the maximum permissible axial deviation of +/-1.5mm between rotor and stator, makes the system suitable for a wide range of applications.
The reversal hysteresis can be disabled avoiding vibration switching of the readings when stationary.
