Pick hardware for the fault,
not for the datasheet.
What you're trying to detect determines the sensor, the sample rate and the mounting. These are the four questions we work through with every client before a parts list is final.
Envelope analysis for early bearing and gear defects
Spalling, pitting and fatigue cracks show up as impulsive, low-energy events that the raw spectrum buries under running speed and its harmonics. Envelope (demodulation) analysis isolates the amplitude modulation carrying those impacts, which is why it catches bearing and gear-mesh faults well before a velocity trend moves. It needs a sensor with real high-frequency headroom — the Phantom G3 samples to 25,600 Hz and returns full waveform, not just an RMS number.

Turbines, centrifugal pumps and motors turning at thousands of RPM produce complex high-frequency signatures best resolved with FFT and high line counts. Robots, conveyors, gearboxes and reciprocating compressors running below a few hundred RPM hide their faults in low-frequency, long-period behavior, where time-waveform and envelope techniques do the work. Same sensor family, different resolution lines and sample rates — worth settling before you order.
Read: Fast vs. slow equipmentCount your gateways before you count your sensors
Sensors are the easy part. BLE range, wall penetration, sensor density per gateway, and whether the location has network drops all decide how many Gateway 2.0 units you need and whether they run on Ethernet, Wi-Fi or cellular. Sites without IT-approved network access typically pair a gateway with the cellular service and a weather-rated enclosure. Defiant 8- and 16-channel units cover assets that need simultaneous wired acquisition.

Mounting method sets the usable frequency range of the measurement. Adhesive-mounted stainless studs preserve high-frequency response and keep the sensor repeatably located shot to shot — which matters, because trending only works if measurements come from the same place. Match stud diameter to the available flat, use the ¼"-28 thread the Phantom sensors ship with, and bond with a structural acrylic rated for the surface temperature.
