Why use the AC202?
- High-performance signal quality – ±5 % sensitivity tolerance and an exceptionally flat ±3 dB response from 0.5 Hz to 15 kHz (30–900 000 CPM) deliver clean data for everything from slow-speed imbalance to early bearing-fault detection.
- Wide 80 g dynamic range – Captures both subtle low-level vibration and severe shock events without clipping when powered from a 22 V (or higher) constant-current IEPE source.
- Rugged, submersible construction – Welded 316 L stainless-steel housing, IP68 hermetic seal, 5 000 g shock rating and 200 ft (60 m) submersion capability thrive in the harshest plant environments.
- Excellent temperature stability – Shear-mode PZT element maintains bias and sensitivity from –58 °F to +250 °F (–50 °C to +121 °C), ensuring repeatable results across seasonal swings.
- Low noise floor – Just 4 µg/√Hz at 100 Hz, allowing earlier fault detection on smooth-running machines.
- Plug-and-play integration – Standard 2-pin MIL-C-5015 top-exit connector or integral-cable options connect to virtually any IEPE data collector, analyzer or online system.
Typical Applications for the AC202 Accelerometer
- Online and route-based condition monitoring
- High-speed turbomachinery and precision spindles
- Pulp-and-paper wet ends and other wash-down zones
- Portable test stand or R&D measurements demanding low noise and high bandwidth
