This model series allows reliable and accurate measurements of static and dynamic torques in both directions of rotation, making it suitable for a large number of applications. The variants of this series constitute standard equipment for quality control, production, assembly and laboratory tests.

Typical applications:

	Screw joint technologies
	• Checking and adjustment of screw tools such as angled torque spanners or screw instruments •  Testing of screw connections
	Measurement of
	• Drag moments on motors and pumps •  Friction moments on gearboxes, bearings and seals •  Torsion springs •  Adjustment devices in the automobile industry (sliding roofs, window lifters etc.)

Description

4 strain gauges are mounted and connected to form a full bridge on a steel sensor element, in the center of the rotatable shaft.
The electrical power supply for the strain gauge full bridge and the measurement signals are transmitted between rotor and stator via a high-grade, 4-fold slip ring system.
Measurement signals are positive for right-hand torques and negative for left-hand torques.
For optional angular measurement, variants 86402-...-V 501 are equipped with a pulse disc. The 2 pulse rows displaced by 90° allow directions of rotation to be identified.
The sensor characteristic values are standardized (1 resp. 2 mV/V) to facilitate tests of the connected amplifier and sensor replacement.
