How do I choose wireless vibration sensors for predictive maintenance?

Check four things: a frequency range that covers the common fault bands, a long battery life, enough wireless range, and an ingress rating that survives your plant. The DHMSCare DS310 sensor covers 0–6000 Hz (±3 dB) and ±16 g and runs 5 years on its battery after activation. It reaches 60–80 m to the gateway inside a plant on industrial-grade Bluetooth 5.0 Class 1 and is IP69-rated. On this hardware, DHMSCare alerts are accurate in 90%+ of cases.
