High axial and radial load allowed
This torque sensor enables the maintenance-free measurement of static and dynamic torques. It opens up new applications thanks to its low price, ease of use and high insensitivity to lateral forces and bending moments.
In addition to classic torque measurement on test benches, in production facilities and for monitoring bolting tools, costeffective torque measurement is also possible in applications including:
Automotive (steering, gearing, motors)
Fitness and workout gears
Mechanical conveying technology
This sensor uses a non-contact and maintenance-free technology to convert the torque into an electrical signal.
The nickel steel shaft is conditioned with a permanent magnetic pattern. Apart from this, no other components such as strain gauges or wiring are required on the shaft.
The magnetic pattern changes as a result of the torque being measured. This produces a measurement signal that is dependent on the torque.
Via the integrated amplifier, the sensor supplies an output voltage of 0.5 ... 4.5 V. The zero point is at 2.5 V, which makes it easy to evaluate the direction of torque.
The measurement solution. It‘s with this ambition and for over half a century burster, a global player in the precision measurement technology industry, supplies some of the world’s most recognizable brands with sensors, precision measuring devices and measuring systems for sensor signaling processing. This is all done through our research, development and production headquarters in Germany.
Where quality assurance and production control play a significant role, burster is on board.
