It holds itself on a ferromagnetic surface by its own magnet and presses the foil strain gauge, protected under a stainless steel foil, so firmly against the surface that friction takes over the task of the adhesive.\u003c\/p\u003e\n\u003cp\u003eMounting takes seconds instead of the three quarters of an hour a bonded gauge needs. The surface is neither cleaned nor ground, and coats of paint do not stop the reading. Calibrated to GF = 2.00, the sensor reads tension and compression directly and can be exchanged without recalibrating the amplifier. It cannot be overloaded – an offset appears instead of damage – and it is used again. The usual instrument for checking FEM calculations and for stress analysis on flat steel structures.\u003c\/p\u003e\n\u003ch2\u003eMeasurement\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDirect reading of the surface strain, like a bonded strain gauge\u003c\/li\u003e\n\u003cli\u003eMeasuring range ± 300 … ± 500 µε, depending on the surface\u003c\/li\u003e\n\u003cli\u003eFoil strain gauge with GF = 2.0, bridge resistance 350 Ω\u003c\/li\u003e\n\u003cli\u003eOne quarter bridge active, 350 Ω completion resistor in the connector\u003c\/li\u003e\n\u003cli\u003eAccuracy and linearity each \u0026lt; ± 0.5 % of RO\u003c\/li\u003e\n\u003cli\u003eSensitivity tolerance ± 0.2 %, transverse sensitivity 0.9 ± 0.2 %\u003c\/li\u003e\n\u003cli\u003eCalibrated to GF = 2.00 for dynamic applications\u003c\/li\u003e\n\u003cli\u003ePassive – external amplifier recommended, such as MBA100, VDA or Monitor DU-1D\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eMounting and use\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMounted and removed in seconds with the tool included\u003c\/li\u003e\n\u003cli\u003eHolds on magnetic structures – no adhesive, no screws, no drilling\u003c\/li\u003e\n\u003cli\u003eThe surface needs neither cleaning nor grinding, and the reading passes through coats of paint\u003c\/li\u003e\n\u003cli\u003eSensors are interchangeable without recalibrating the amplifier\u003c\/li\u003e\n\u003cli\u003eReusable – no single-use material, no consumables\u003c\/li\u003e\n\u003cli\u003eSteel housing Ø 34 mm, 36 mm high, protection IP54\u003c\/li\u003e\n\u003cli\u003eSupply 5 V DC, 8 V DC at most, current draw below 15 mA\u003c\/li\u003e\n\u003cli\u003eOperating temperature 0 … +50 °C, storage 0 … +70 °C\u003c\/li\u003e\n\u003cli\u003eWeight including cable 200 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCable lengths\u003c\/h2\u003e\n\u003cp\u003e3 m as standard; 0.5 m, 5 m and 10 m are available, as is any intermediate length from 0.5 to 10 m.
