330400/ 330425 Accelerometers
Brand : Bently Nevada

Accelerometer

The 330400 accelerometer is designed for general-purpose casing acceleration measurements and meets all requirements of API 670. The 330425 is identical except it provides a broader amplitude range ( 75 g peak) and a sensitivity of 25 mV/ g peak. Neither transducer requires an external interface module.

Electrical :
1. 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 Noise Floor : ( 10 Hz to 15 kHz) 0.039 m/ s2 ( 0.004 g) rms.

2. 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. Put on Product PartnerRecommend to your friends
