• Description

  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 gages 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.

  Areas of application:

  • Automotive (steering, gearing, motors)
  • Drilling systems
  • Textile machines
  • Pumps, mechanical conveying technology
  • Fitness and workout gears, household appliances
