Introduction
ABC-MEMS
is the third generation of
ABC
Instrument’s smart vibration meter/datalogger. It
includes It includes a 3-axis MEMS accelerometer, an accurate date/time clock, a non-volatile 128 Mb
recording memory and
wireless
connectivity with fast USB and
WiFi™
download. Depending on the
settings it can record vibration/velocity signals and/or RMS vibration/velocity levels for months. Its very
small size allows it to be attached to, or embedded within, the monitored equipment.
The
ABC-Mems
model is an evolution of the
1e
model. It has the following new
features:
•
Can measure, record and trigger on velocity signals, in addition to acceleration signals.
•
Has
WiFi™
reporting and email alarms.
•
Includes an accelerometer with exceptional noise floor (20 times better noise floor than the
Vibration
Mems
-16g).
•
Sampling rates up to 4 kHz.
•
Improved anti-aliasing filter.
The
ABC-Mems
includes the following features:
•
3-Axis integral MEMS accelerometer
•
Measures and records:
o
Raw acceleration or velocity signals
o
Acceleration or velocity signal statistics
o
Vibration or velocity RMS levels
o
Inclinations
•
All-digital design.
•
Integrated oscilloscope function that can show the vibration or velocity signals in real time.
•
Allows the observation of recorded data while the recording is ongoing.
•
Works standalone, or USB or
WiFi™
connected for setup and data transfer to PC.
•
Long life internal rechargeable battery that recharges from USB.
•
Self-calibrated using the earth’s gravity as a reference.
•
Observes and records 100% of the acceleration signals (no missed samples).
•
Editable individual custom ID for easier instrument management.
•
Completely sealed weatherproof enclosure.

Applications
•
Building-health monitoring on construction sites.
•
Long-term seismic monitoring.
•
Long-term inclination monitoring.
•
Long-term measurement and recording of acceleration signals, velocity signals, signal
statistics (peaks and average) and RMS levels.
•
Continuous monitoring of machinery wear.
