Series 85040 and 85070 for compressive load, for tensile and compressive forces For static and dynamic forces High linearity from ± 0.1 % F.S. Very low sensitivity to lateral forces Models 85073 / 85075 suitable for extremely high dynamic stress, series 85070 up to 109 load cycles Extended temperature compensation range -55 °C to 120 °C (optional) Measuring ranges from 0 ... 20 N to 0 ... 2 MN Protection class IP68 (optional) 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. 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). 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. Technical changes reserved. All data sheets at www.burster.com 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. burster praezisionsmesstechnik gmbh & co kg Germany Talstr. 1-5 .

Dimensions Compressive load cell model 85043 - for static and dynamic operations Order Code Measurement Range Compressive load cell sensor model 85073 - also suitable for highest dynamic operations Order Code Measurement Range Dimensional drawings models 85043 and 85073 from 50 kN Permitted external forces As a result of the two stabilizing membranes with which these load cells have been designed, they only have very low sensitivity to forces that do not act centrally on the sensor. The effect of these undesirable external forces cannot be expressed in blanket figures; it depends on the sensor‘s...

A hole in the mounting surface allows force to be applied from below. If the sensor is mounted on a surface that has not been drilled, it is necessary to ensure that the threaded bolt that is screwed in from above does not press...
