IEPE Accelerometer Series
Datasheet

Bently Nevada Machinery Condition Monitoring

124M2609 Rev. DDescription
This series of Integrated Electronics Piezo-Electric (IEPE)
accelerometers are optimized for obtaining high quality
vibration signals in harsh industrial environments. Their piezo
sensing elements provide exceptional dynamic range,
frequency range and linearity, while their integrated
amplifiers boost the signal, making them relatively immune
to electrical noise.
They require an industry standard constant-current power
supply, and provide an output voltage proportional to theacceleration signal. So they can interface to a wide variety ofcondition monitoring systems.
Within the series are options for 100 or 500 mV/g sensitivity,
top-exit or side-exit connector, and several hazardous-areacertification levels.

FeaturesllllllRugged stainless design, corrosion resistant
Hermetic seal, case isolated
ESD protection
Reverse wiring protection
EMI / RFI shielded
Hazardous area certifications

Benefits
llllllAble to fit in small spaces
Light weight for walk around programs
Cross wiring does not harm sensor
Prevents ground loops in permanent mountapplications
Can be hosed down or submersed with proper
connector
Can be used in applicable certified hazardous areas
