1.0 INTRODUCTION
With this torque sensor the effective torque on the gauge bar can be measured bi-directionally
independent from rotational speed. The sensor is delivered as a complete unit with corresponding
connecting cable and key stones. The transmitting shaft, the contact-free signal pick-up and the analog
signal processing are integrated into the sensor structure. No external amplifier is needed. Based on
magnetic field and therefore completely non-contact measurement principle, the sensor works totally
maintenance-free over a wide temperature range.
• Torque sensor with non-contact principle
