3 AXES VIBRATION AND SHOCK SENSOR • 4÷20 mA Output • M12x1 connector output • General features: These new accelerometers give a single 4 ÷ 20 mA signal proportional to the vibrations applied to X, Y and Z axes. Since the measurement is made from a very low frequency, the acceleration due to gravity is not detected, so the measurement will not be affected by the mounting position. Depending on the connection polarity (direct or reverse) it’s possible to perform the RMS measurement on the vectorial sum of the acceleration on the three axes X, Y and Z or the instantaneous value , simply reversing the two connection wires. On the version VBS… (bump sensor) the highest instantaneous value is held on the output for one second, allowing analogue value measurement. For a reliable connection it is recommended to use M12x1 connectors with the shield of the cable connected to the nut (see section H of the catalogue). Applications: • Collision detection on electrospindles, handles and robot arms • Unbalancing detection of tools on milling and grinding machines • Detection of wearing or abnormal working of ball bearings and rotating parts • Detection of incorrect loading of drum in washing machines • Out of balance loads on rotating machinery Technical data: • Measuring range: ± 6 g, ± 10 g • Supply voltage: 8 ÷ 40 Vdc • Output current : 4 ÷ 20 mA • Output current variation: see the table • Hold time of the peak value (version VBS…) 1 sec. • Frequency range: 2 ÷ 300 Hz • Max survival shock: 2000 g • Working temperature: — 20° ÷ + 80° C • Degree of ingress protection: IP68/IP69K • Shock and vibration resistance according to EN60068-2-27 EN60068-2-6
