Why choose the AC140 Accelerometer?
| Benefit | What it means for you |
|---|---|
| Miniature footprint – Ø 0.48 in (12 mm) body, 0.7 oz mass | Mount on small motors, spindles, robotics arms or inside crowded guards without mass-loading the machine. |
| Wide usable bandwidth – 36 – 900 k CPM (0.6 – 15 kHz, ±3 dB) | Capture both slow-speed bearing defects and high-frequency gear mesh harmonics. |
| −58 °F → +250 °F (−50 °C → +121 °C) | One part number for cryogenic, ambient, and hot-process locations. |
| Hermetically welded 316 L stainless housing (IP68) | Submersible to 60 m; resists chemicals, wash-downs and corrosive atmospheres. |
| 5 000 g shock & SIL 2 rating | Survives rough handling and qualifies for safety-instrumented protection loops. |
| Food-safe cable option | “-6N” integral cable uses FDA-compliant heat-shrink for hygienic zones. |
Typical use cases for the Industrial Accelerometer
- Route-based vibration surveys where sensor weight and cable clearance are critical
- Small fractional-horsepower motors, fans, pumps and gearboxes
- Spindle and tool monitoring on CNC machines
- Robotics, drones and lightweight test fixtures
- Hygienic or wash-down environments (integral FDA cable)
