The AM3100T2-Z2 is an Integrated Electronics Piezo-Electric (IEPE) accelerometer optimized for obtaining high quality vibration signals in harsh industrial environments. Its piezo sensing element provides exceptional dynamic range, frequency range, and linearity, while the integrated amplifier boosts the signal and improves immunity to electrical noise.
The sensor requires an industry standard constant-current power supply and provides an output voltage proportional to the acceleration signal, allowing interface with a wide variety of condition monitoring systems.
The AM3100T2-Z2 features a top-exit connector configuration, 100 mV/g sensitivity, and Zone 2 hazardous-area certification.

Frequency response and spectral noise values are typical.
Install the sensor on a clean, flat, and rigid mounting surface. Remove paint, rust, grease, and debris before installation to ensure proper mechanical coupling and accurate vibration transmission.
Poor mounting surfaces may reduce high-frequency response and introduce measurement errors.
Use the supplied ¼-28 mounting stud for installation.
Installation recommendations:
Use shielded twisted-pair cable as recommended by the manufacturer.
For best signal quality:
Recommended cable length should not exceed 100 feet.
