Product Description

Product Description

 

Description:

The force to be measured is introduced via the threaded pin in the directions of both tension and compression in the cylindrically shaped sensor body. Torsion and bending forces must be avoided. It is not absolutely necessary that the interior threaded parts are seated solidly on the end of the threads or floor surface of the sensor housing. It suffices to apply the forces via the threadings, but they have to be fixed by a nut or pinch screw. Two stabilizing membranes in the interior of the sensor reduce the lateral force and torque to a minimum and guarantee high long-term stability of the electrical and mechanical values. The network for temperature compensation or standardiza

tion is positioned on a covered board as a thickened part of the sensor's connecting cable. The maximum static usage force is the greatest force in the direction of the measurement axis that the sensor can endure. The overload protection is not suitable for using the sensor often in the overload range nor for sudden loads. The sensors work independent of positioning and have an active side which effects the measuring element directly, whereas the passive side is solidly connected to the housing.

Model 8432 with overload protection for directions

tension and compression

Application situation :

Precise tension and compression force measurements can be performed in limited space with model 8431 and 8432 precision miniature load cells. High precision, various measuring ranges, convenient load application via threaded pins with external winding and small dimensions offer a wide scope of

applications in laboratories and production. The series are among our most precise and yet mechanically sturdy miniature load cells. All options, typical only for larger load cells, are available with this miniature series such as hermetically sealed construction, overload protection and boring for pressure compensation when applied under vacuum. Its complex design with integrated support membranes and overload protection reduces additional construction effort for external overload protection or guidance of force of applied parts in many applications. This requires little space, has little material and weight and almost no component friction, which could falsifythemeasurement result. The connection cable suitable for robot applications make the precision miniature load cells especially suitable for use in the areas of special purpose machinery manufacture, tool manufacturing and handling gear.
