Triaxial accelerometer SV 85

piezoelectrichermeticindustrial

The SV 85 is a ICP® based TRI-AXIAL ACCELEROMETER designed for general purpose vibration measurements with the SVAN 958A four-channel analyser. The HERMETIC SEALED tri-axial industrial piezoelectric accelerometer is suitable to monitor the vibration in harsh industrial environment. The signal ground is ISOLATED from the mounting surface and outer case to prevent ground loops. Features: Piezoelectic accelerometer dedicated to building/ground structure vibration measurements Compatible with SVAN 958A and SV 106 Hermetically sealed SV 84 Building/Ground Vibration Acelerometer Specification 300 μg RMS Performance: Number of axis: 3 Sensitivity (± 10 %): 10 mV/(ms-2) ~ 100 mV/g Measurement range: 0.005 m/s2 RMS ÷ 500 m/s2 Peak Frequency response (± 3 db): 0.5 Hz ÷ 13 000 Hz (Z axis); 0.5 Hz ÷ 10 000 Hz (X, Y axis) Linearity: ± 1 % Residual noise (1 Hz, 24°C): 300 μg RMS Residual noise (1 kHz, 24°C): 3000 μg RMS Transverse response sensitivity (20 Hz, 50 m/s2): 100 mΩ Dual case isolationinternal Faraday shield (suitable for permanent installation Supply current (IEPE): 2 mA ÷ 10 mA Supply voltage (IEPE): 22 V ÷ 28 V Bias voltage (IEPE)+12 +/- : 2 VDC Output impedance (Nominal): 50 Ω Charge/discharge time constant (start-up time): < 1 sec. typ.
