This tensile force sensor is an especially small component which can be easily integrated into a girder assembly, between two cables or chains, for measuring force. The outer threading along its axis can accommodate various adapters, or alternatively it is very easy to drill a threaded hole in which this sensor can be inserted.
The radial connection cable is suitable for robotics applications; i.e. it is extremely flexible and designed for a wide range of movements. In order to achieve the greatest possible stability for such a small sensor, making it suitable not only for the laboratory but also for industrial use, all parts have been welded together, including the cable guide bush in the sensor housing.
Typical uses are the determination of forces in a Bowden cable, testing the durability of soldered and welded joints, measuring tractive force of a plug-model connection, or monitoring the forces during winding of cables onto cable drums.

Description

Force sensor model 8417 measures the tensile or compressive force between both axially mounted metric exterior threads on the cylindrical sensor housing with a typical accuracy better 0.5 % F.S.
Forces are only applied to the threading and must not be affected by external components such as bending, transverse force or torsion.
Any contact with units affixed to the sensor housing - especially at its front ends - surfaces must be avoided.
The measurement element is a membrane perpendicular to the axis of the sensor with a full bridge of wire strain gauge applied to the inner surface requiring a stable voltage feed with a rated value of approx. 1.2 mV/V.
The connection cable is fed radially through a sleeve from the housing. A standardisation of the output to 1.0 mV/V into the cable is also available.
