How do I choose wireless vibration sensors for predictive maintenance?

Look at four parameters: a frequency range that covers common fault bands, long battery life, enough wireless range, and an ingress rating that survives the plant environment. The DHMSCare DT310 sensor covers 0–6000 Hz (±3 dB) and ±16 g, runs 5 years on its battery after activation, reaches 60–80 m to the gateway inside a plant on industrial-grade Bluetooth 5.0 Class 1, and is IP69-rated. DHMSCare delivers alerts accurate in 90%+ of cases on this hardware.
