Why use the AC192 Accelerometer?
- Wide, flat bandwidth in a tiny package – ±3 dB from 0.4 Hz to 13 kHz (24 – 780 000 CPM) allows one sensor to capture everything from slow-roll unbalance to high-frequency bearing defects [0].
- Very low noise / high RF immunity – Spectral noise only 8 µg/√Hz at 10 Hz and < 2 µg/√Hz above 1 kHz; internal shielding and shear-mode element reject EMI and thermal transients [0].
- Rugged & submersible – 316 L stainless body, laser-welded hermetic seal and IP-68 rating for 60 m (200 ft) continuous submersion [0].
- Flexible cabling options – Standard 2-pin MIL connector (–1D) or integral polyurethane, armored stainless, or FDA-compliant hygienic cables (–2D/3D/6D/6N) for permanent installs [0].
- Lifetime warranty & SIL 2 – Certified safety integrity and CTC’s unconditional lifetime replacement guarantee.
Typical Applications for the AC192 Accelerometer
- Route-based data collection on motors, pumps, gearboxes where minimal mass is critical
- OEM machinery and tight-clearance bearing blocks
- Immersion or wash-down processes (food, beverage, pharmaceutical)
- Portable magnet-mount surveys with low added weight
- General-purpose condition monitoring when budget and footprint matter
