3500/42-01-00  (176449-02+128229-01)   Proximitor Seismic Monitor Bently Nevada

9200 and 74712 Vibration speed sensors
Unless otherwise stated, specifications are measured at +22°c (+72°F) and 25 mm/s (1 in/s) at 100Hz.
Electrical characteristics
Sensitivity: 20mV/mm/s (500mV/in/s)±5% at 10OHz(6,000 cpm) and 25mm/s(1 in/s) zero to peak ±5% at 10OHz(6,000 cpm) when properly terminated and positioned at the calibration Angle
Frequency response: from a small operating frequency (see ordering information) to 1kHz(60,000 cpm); Typical values range from +0 to ±3dB Impact resistance: Withstands 50g peak acceleration
Lateral sensitivity :±10%
Lead length: Longer 305m(1,000 ft) between the vibration and 3300 monitor. Frequency attenuation as length increases. Environmental restriction
