±8g 3-Axis Industrial Accelerometer

Description

The ±8g 3-Axis Industrial Accelerometer is the workhorse of the range. It is built for machine vibration monitoring and predictive maintenance — motors, pumps, fans, compressors and gearboxes, the rotating equipment that most plants start with when they build a condition monitoring program.

Healthy rotating machines usually generate vibration in the low single digits of g, and that number climbs as bearings wear, couplings misalign or impellers go out of balance. With 0.01g accuracy and 0.001g resolution, this model resolves those changes early enough to act on them, and ±8g leaves enough headroom for start-up surges and the occasional upset without clipping. It is the range we recommend first unless you already know your amplitudes are smaller or larger. It sits in the middle of our industrial accelerometers range, which runs from ±2g to ±32g on one shared platform.

Key Specifications

Output Options

Typical Applications

• Motor and pump condition monitoring — bearing wear, imbalance, misalignment
• Fan and blower vibration in HVAC, boilers and dust collection
• Gearbox monitoring on conveyors, mixers and crushers
• Predictive maintenance programs built around ISO 10816 machine vibration severity
• Compressor and chiller health checks in plant utilities

Mount it as close to the bearing as you can, on a flat, clean surface, and keep the cable clear of moving parts — mounting quality affects readings more than most people expect. If you are measuring a slow, near-static tilt rather than running vibration, our inclinometers are the right tool. If the machine is mobile or takes regular impacts, read the ±16g model first.

Frequently Asked Questions

How do I pick the right measuring range? As a working rule, your normal operating acceleration should sit at roughly one-third to one-half of the full range. That leaves headroom for start-up transients and fault conditions without wasting resolution. If your machine normally sees 0.5g, ±2g is right; if it sees 3-4g during normal running, move to ±8g and keep ±16g for shock events.

Which output should I choose? CAN for vehicles and mobile machinery where a bus already exists; 4-20mA for long cable runs and direct PLC/SCADA input; RS485 (Modbus RTU) when you want multiple sensors on one digital network; 0-10V for short, cost-sensitive runs. Our CAN version is in stock now — the other three are available on request.

Can you customize the sensor for our application? Yes. Range, output type, cable length, connector and mounting are all configurable, and we do OEM/ODM runs. Send us the machine type, speed, mounting position, and what you need to detect, and we will come back with a recommendation.
