Description
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 falsify the measurement 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
- Handling gear
The force to be measured is applied to the cylindrical sensor unit in the tension or compression direction by means of the two external threads. This means that the sensor must be mounted without any attachments touching the end faces of the sensor housing. This avoids excessive contact pressures on the material and tensions inside the sensor that would affect its measuring element. Please refer to the sensor user manual for guidance on the various options for fitting the sensor, which depend amongst other factors on its measurement range. Although the precision miniature load cell is designed to isolate the measuring element from external forces, torsion and bending moments should be avoided.
Two stabilizing support diaphragms inside the sensors for small measurement ranges minimize the effect of transverse forces and moments and ensure long-term mechanical stability for measurements. The network for temperature compensation or standardization of the output signal is located on a sheathed circuit board in a wider section of the sensor's connecting cable. The maximum static operational force is the maximum force in the direction of the measurement axis that the sensor can tolerate. The overload protection is not designed for frequent use of the sensor in the overload range or for sudden loads. The sensors work in any orientation. They have an active side which acts directly on the measuring element, whereas the passive side is fixed to the housing.
