Precision Tension and Compression Load Cell Model 8524 Large measurement ranges Small measurement ranges Medium measurement ranges Optional overload protection up to the fivefold of measurement range Application Due to their compact design and construction, these tension-pressure load cells can be operated without any problems in laboratories as well as in industrial environments. Made of corrosion-resistant steel, these load cells can be integrated easily in existing structures, due to their standardized nominal characteristic value and simple assembly. Model 8524 can be used to measure static, semi-static and dynamic tension and compression forces depending on the measurement task. Areas of application include: ► Measurement of press-in and insertion forces ► Measurement of spring forces ► Measurement of shearing and cutting forces ► Force measurement and control during assembly ► Measurement of pressure on drilling machines A load-centering plate mounted on the load cell can be used to measure joint lugs, tension forces in ropes, chains, etc. (refer to page 4: load-centering plate). ■ Measuring ranges from 0 ... 500 N to 0 ... 200 kN ■ Measurement accuracy better than 0.25 % F.S. ■ Output signal 1.5 mV/V, standardized ■ Highly versatile and for universal use ■ Type of protection acc. EN 60529 IP67 for measuring ranges > 0 ... 20 kN ■ Linearity error 0.1 % F.S. for measuring ranges < 0 ... 5 kN (option) ■ Cable suitable for drag chains and highly flexible Description The bending diaphragm inside the load cell is equipped with strain gauges which, on the exertion of a force, supply a bridge-output voltage directly proportional to the measurement variable. The center axis of the tension/ compression load cells incorporates a continuous thread through which the measurement force is applied free from lateral or torsion force either using a load application button or an application-specific adapter part. Starting at a measurement range of 0 ... 5 kN, the measurement accuracy is ideal if the load cell has been mounted on a levelled, hard and polished base. This condition is not necessary for small measurement ranges of 0 ... 2 kN due to 3 special knife-edge bearings (see dimensional drawing 1). Structural measures should be taken to avoid exposing the load cell to lateral forces (for instance, mounting on movable bearings, levers held by roller bearings). Attachment via the clearance bore holes integrated in the external ring allows simple handling of the sensor. A stop serves as overload protection against damages caused by impermissible high compression forces (option up to measurement range 0 ... 20 kN). Lateral forces of up to 5 % nominal strength only have little influence.

Pull Plates A pull plate extends the range of application of flat-design tension-pressure load cells to include the measurement of tensile forces in freely movable arrangements (rope tension, joint tension ...). A pull plate has roughly the same dimensions as the sensor body and is mounted on the load cell (see drawing). The central tapped holes allow an installation of customer-specific or standard threaded components (for example, joint heads). Order Code Screws of strength class 12.9 are required for attaching the pull plates to the load cells. Mobile high-precision calibrator and...
