Tension-Compression Load CellsModel 8523 Application These sensor series are especially suitable for the measurement of static and semi-static tension and compression measurements. The membrane load cells are designed based on proven principles. Their compact design and very solid construction makes them suitable for use in manufacturing plants as well as in laboratories and testing. Sensor characteristic value is standardized with the exception of model 8523-20/50 N. This makes it possible to replace the measurement amplifier without adjusting it. Furthermore it is possible to connect several load with the same measurement range at the same time by totaling the individual forces. Applications: ► Cable force ► Measurement of bar, rods and framework forces ► Press-fit processes ► Balance and test scales ► Friction forces ► Withdrawal forces ■ Measuring ranges from 0 ... 20 N to 0 ... 5000 N ■ High measurement accuracy up to 0.15 % F.S. ■ Material high-strength aluminium ■ Standardized nominal characteristic value starting with a measurement range of 0 ... 100 N ■ Especially inexpensive Description The load to be measured is applied either using a load button or an application specific thread part to the load cell via a M8 thread, which is located in the axis of the tension and compression sensors. A strain gauge full bridge is in the sensor element, which converts the applied load into an electrical signal. The mounting of the load cells is unproblematic due to the three-point support. This reduces the mounting surface requirements. In order to achieve an optimal measuring result, the force to be measured must be applied to the sensor axially. Lateral forces can be avoided by constructional measures like mounting the load cell on movable bearings, guiding sleeves, etc. Load buttons (see drawings) enable an optimal appliance of the compression forces to the load cells. The measurement error upon non-axial load application is negligible up to an angle error of 3° due to the sensor’s convex surface. The output signal is positive in the calibrated direction of motion (compression force). The characteristic value in the direction of tension can deviate from the calibrated direction of compression by up to 0.3 %. Technical changes reserved.
