Specifications
Parameters are specified from +20 to +30 °C
(+68 to +86 °F) and 100 Hz unless otherwise
indicated.
Operation outside the specified limits may
result in false readings or loss of machine
monitoring.
Electrical
330400
Sensitivity 10.2 mV/m/s2 (100 mV/g) ±5%.
Acceleration
range
490 m/s2 (50 g) peak overall
acceleration within the 10 Hz to 15
kHz frequency span. Vibration at
frequencies above 15 kHz, especially
at the transducers resonance will
significantly decrease this range.
Amplitude
Linearity
±1% to 490 m/ s2 (50 g) peak.
Broadband

(10 Hz to 15
kHz)
0.039 m/s2 (0.004 g) rms.
330425
Sensitivity 2.5 mV/m/s2 (25 mV/g) ±5%.
Acceleration
Range
735 m/s2 (75 g) peak overall
acceleration within the 10 Hz to 15
kHz frequency span. Vibration at
frequencies above 15 kHz, especially
at the transducer’s resonance, will
significantly decrease this range.
Amplitude
Linearity
±1% to 735 m/s2 (75 g) peak.
Broadband
Noise Floor
(10 Hz to 15
kHz)
0.098 m/s2 (0.01 g) rms.

10 Hz to 15 kHz
(600 cpm to 900,000 cpm) ±3dB;
30 Hz to 10 kHz
(1800 cpm to 600,000 cpm) ±10%
Temperature
Sensitivity
-11% to +3% typical over the
operating temperature range.
Transverse

20 dB maximum.
Base Strain Sensitivity
For serial
numbers
preceded by
the letter “G”
(including all
new sensors
49 mm/s2/mstrain (0.005 g/mstrain)
For serial
numbers NOT
preceded by
the letter “G”
(shipped
prior to April
2004)
980 mm/s2/mstrain (0.100 g/mstrain)
without Mounting Base (API
adapter);
4.9 mm/s2/mstrain (0.0005 g/mstrain)
with Mounting Base (API adapter)
supplied with the accelerometer.
Bently Nevada recommends
installing with the Mounting base to
minimize base strain sensitivity for
serial numbers NOT preceded by the
letter “G”.
Maximum
cable length
305 metres (1000 ft) with no
degradation of signal.
Power requirements
Input Voltage -24 ± 0.5 Vdc.
