These load cells feature an outstanding ability to withstand static and dynamic stress and have exceptional precision and service life. These products have a huge range of applications in industry, R+D and testing thanks to the optional IP68 degree of protection and low sensitivity to lateral forces.
Examples of applications would be the measurement of:
- Insertion forces
- Reference measurement
- Weights (e.g. silos, skips)
- Tensile forces (tension in cables, chains etc. with load centering plate)
- Materials testing
For the compressive force sensors (models 85043 and 85073) the force must be applied through a plane plate, hard enough for the range of forces being measured, or a piston.
The force-sensitive diaphragm with fitted strain gauges is located between the central part, where the force is applied (force application), and the outer ring (containing fixing holes).
Two support diaphragms are additionally fitted, above and below the actual measuring element, to desensitize the sensors to extraneous lateral forces or moments. (see „Permitted external forces“ on page 2).
Models 85041/85075 (tension/compression) are calibrated in the tensile direction. The characteristic figure for the compression direction can nominally vary by ± 0.25 % from the figure for the tensile direction. The output signal is positive when the applied force is tensile.
The 8507X series (models 85073 and 85075) is designed for the highest possible dynamic stress and service life. This is > 109 cycles from zero up to the full value of the measuring range in the tensile or compressive direction and tolerates a maximum operational force of up to 200 % of the nominal range.
