NE3502D proof vibration sensors

Overview NE3502 series transmitters built MEMS piezoelectric element induced vibration velocity, acceleration by high-precision integrated circuit will be converted to velocity peak / RMS; then speed Peak / RMS converted into 4 ~ 20mA current output corresponds to the range; the ideal to be connected to DCS, PLC and data acquisition system medium. To provide the most stable detection circuit, built-temperature impact protection, offers a variety of mounting screw, a variety of vibration measuring range, excellent frequency response characteristics, high accuracy, wide application range, is ideal for fans, pumps and other rotating machinery vibration monitoring. Technical Specifications Power: 14 ~ 28VDC power supply, the maximum power consumption 0.5W; measuring range: the sensitive direction 10 ~ 2000Hz;; -3dB, the maximum 5 percent:: axial speed in any direction RMS / peak, range selectable frequency range / angle of installation; transverse sensitivity: ≤3%; housing materials: 316L stainless steel shell, inside sealed with epoxy filler; electrical isolation: 500Vrms, circuit isolation and housing; lead the way: (1) Top Grommet (2) with protective box terminal outlet Current output: speed RMS / peak proportional 4-20mA DC current accuracy: better than ± 3%.
