What makes the AC244 stand out?
Miniature form, maximum bandwidth
Only 2.1 oz (60 g) of 316 L stainless steel, yet the shear-mode ceramic element delivers a resonance near 33 kHz and a flat, usable response from 36 to 900 kCPM (0.6 – 15 kHz, ±3 dB) – perfect for high-speed spindles, turbines and small rotating assets 1.Premium build for harsh plants
• Welded hermetic seal, IP68-rated to 200 ft (60 m) submersion
• Survives 5 000 g shock and –58 °F to 250 °F (–50 °C – 121 °C) operating range [1].Plug-and-play IEPE electronics
Runs on any 18–30 V DC, 2–10 mA constant-current source. Bias voltage 10–14 V simplifies health checks. The 2-pin mini-MIL connector or integral cable options drop straight into existing route-based or online systems.Wide dynamic span
±80 g peak dynamic range lets you capture everything from rolling-element bearing chatter to severe imbalance without clipping [1].Certified peace of mind
SIL-2 safety rating for critical applications and CE electromagnetic compliance.
Typical Applications for a small size Accelerometer
• High-speed electric motors and micro-turbines
• CNC machine spindles and toolholders
• Gearboxes with limited mounting real estate
• Pump, fan and blower vibration programs where sensor mass must be minimised.

Why choose the AC244?
- Detect early-stage faults on high-speed assets thanks to superior high-frequency fidelity.
- Reduce downtime: hermetic sealing and stainless housing thrive in wash-downs, oil spray and caustic atmospheres.
- Simplify spares – one compact, 100 mV/g accelerometer fits most route-based and online IEPE channels.
Bring miniature precision to your condition-monitoring program with the AC244 – where premium build quality meets miniature convenience.
