E xtended temperature range of -30 ... +120 °C S tandardized nominal sensitivity 1.5 mV/V b urster TEDS O verload protection up to 5 times the nominal force P ull plate and rod end bearings Large measuring ranges Applications All areas of mechanical engineering Assembly and joining equipment Hydraulic presses Measurement of cable strengths Product description Medium measuring ranges (with accessories) Small measuring ranges The 8524 precision tension & compression load cell is a versatile sensor for highly accurate load measurements in diverse applications. Optimum measurement quality is achieved with the load cell mounted on a flat, hard and polished contact surface. This requirement does not apply to small measurement ranges of up to 0 ... 2 kN because three knife-edge bearings ensure that the sensor is seated securely. Our brochure „Load Cells“ explains how you can design parasitic loads out of your mechanical system. Through-holes in the outer flange are used for fastening the 8524 sensor to the system structure. The load is applied via the central blind threaded hole or optionally via a load button. Alternatively, a pull plate and even rod end bearings, if desired, can be attached to the sensor for equally easy measurement of purely tensile loads, for instance in Bowden cables or chains. The 8524 sensor is designed to measure static, quasi-static and dynamic compressive and/or tensile loads. Inside the sensor is an elastic membrane, on which are applied strain gages connected in a full Wheatstone bridge. If a tensile or compressive load is applied to the sensor, the ohmic resistance of the measuring bridge changes and detunes the output signal in proportion to the measured load in mV/V. burster Sensors and Process Instruments – Technical changes reserved.

Options Overload protection in compression direction Example for measuring range 0 ... 20 kN The optional overload protection guards a load cell against damage under a static load that exceeds the safe load (150% of the rated load). The overload protection is available up to the measurement range of ≤ 20 kN. Protection is achieved via a mechanical stop, which limits the measurement displacement of the sensor (to about 80 µm). The overload protection contains additional holes for mounting on a fixed system structure, which then allows the transmission and measurement of tensile loads as...

Accessories Rod end bearings The 8524 load cell can be optionally supplied with a rod end bearing. In combination with a pull plate (see option), up to two rod end bearings can be used. Rod end bearings ensure optimum load application when the sensor is used in the tension direction. In addition, they can compensate for slight misalignment in the compression direction.
