Made in USA
No software to install and no cloud account to create. Mount the sensor to the machine, power it on, and start streaming 3-axis vibration over your own self-healing wireless mesh.
Attach the IP67 sensor directly to a motor, pump, or gearbox, with a magnetic mount for a quick survey, or the ¼”-28 UNF thread for a permanent stud.
The hybrid D-cell and supercapacitor power source runs for years with no wiring to pull. Battery level reports with every transmission, so you always know power is healthy.
The sensor joins a self-healing wireless mesh network, with up to 2-mile line-of-sight range, relaying through repeaters to blanket coverage across the plant.
Watch RMS velocity, peak acceleration, and temperature trend in your Atrium dashboard, and let threshold alerts open a work order the moment a signature climbs.
Both share the same 3-axis vibration core and Atrium platform. The difference is the form factor: this one seals the accelerometer, the radio and the antenna into a single puck that mounts straight onto the machine, so there is no probe to route and nothing that has to stay clear of a washdown.
Pair these sensors with an Atrium Gateway, open a browser on your network, and drag the readings you care about onto a dashboard. No code to write.
Industrial-grade condition monitoring, delivered wirelessly and reliably.
A 3-axis accelerometer sampling up to 25.6 kHz at ±16g captures both time-domain waveforms and overall vibration, with on-board FFT resolving the frequency detail that separates imbalance from early bearing wear.
Edge intelligence runs on the sensor, with motion-detect wake, on-board learning, and asset-runtime reporting, so you learn not just how a machine vibrates, but how long it actually runs.
The sensor samples continuously and wakes the instant vibration crosses a set threshold, capturing the event and sending it on. Machines that cycle on and off, like compressors, stay covered even when they run at odd hours.
A hybrid D-cell and supercapacitor power source delivers up to 5 years of life, with battery level reported on every transmission so you can plan replacements.
A fully sealed IP67-rated enclosure stands up to dust, washdown, and moisture on the plant floor, with magnetic and ¼”-28 UNF stud mounting to fit any machine.
Sub-gigahertz radio on the 868 / 900 MHz bands travels farther and penetrates walls and machinery far better than higher-frequency Wi-Fi or Bluetooth, so the sensor keeps reporting from deep inside the plant.

Anything that spins, pumps or rotates builds a vibration signature, whether it sits on a plant floor, in a quarry, at a pump station or on a rooftop.
Predictive MaintenanceTrend vibration over time to schedule repairs on your terms, before a fault becomes a failure.
Motor & Pump MonitoringCatch bearing wear, cavitation and imbalance on process pumps, wastewater lift-station pumps and the motors that keep production moving.
Fan & Blower BalancingDetect imbalance and looseness on process fans and power-plant blowers before it shakes the whole assembly loose.
Compressor & Gearbox HealthWatch gear-mesh and compressor signatures, including compressors at remote oil and gas sites, for the early roughness that precedes a costly rebuild.
Conveyor & Bearing MonitoringKeep tabs on rollers, idlers and drive bearings across long conveyor runs and paper-mill roll drives on a single mesh.
HVAC & Rotating EquipmentMonitor chillers, AHUs and rooftop units across a building or campus without running power or signal wire.
Crushers & Vibrating ScreensA screen deck in a mine or quarry is meant to shake. Trend its signature to tell normal motion from a drive bearing that is coming apart.
Mixers & AgitatorsAgitator gearboxes and shaft bearings in food, beverage and pharmaceutical plants sit on batches you can’t stop halfway through.
Centrifuges & SeparatorsA high-speed bowl has to stay balanced to stay safe. Uneven buildup shows up as imbalance well before the machine trips.
The math is simple. One purchase versus compounding monthly fees.
Vibration tells you how the machine is wearing. These sensors add load, pressure and run hours on the same Atrium gateway.
3-Channel AC Current MonitorClamp a CT on each phase feeding the motor. Current draw shows load and whether it is running, next to the vibration trend.
Pressure and Temperature SensorThread it into the pump discharge. A clogging filter or a failing pump shows up as pressure on the same dashboard.
Machine Runtime Hour MeterMagnet-mount it to the machine. Run hours set the schedule for greasing and service.
Everything you need to know about the Industrial IoT Wireless Smart Vibration Sensor Gen4.
It measures 3-axis vibration with both time-domain and overall vibration readings, plus temperature. A 3-axis accelerometer samples at up to 25.6 kHz across a ±16g full-scale range, with on-board FFT for frequency-domain analysis, and a built-in temperature sensor reads to ±1 °C.
The accelerometer samples at up to 25.6 kHz. A high sample rate captures the higher-frequency content where early bearing and gear faults first appear, so you can separate imbalance from bearing wear rather than just seeing an overall vibration number rise.
Yes. The sensor includes built-in machine learning and is always listening with motion-detect wake, and it reports asset runtime, so you learn not just how a machine vibrates, but how long it actually runs between idle periods.
Yes. Alongside vibration it reports temperature to ±1 °C accuracy, giving you correlated vibration and temperature signals from a single sensor.
Up to 2 miles line-of-sight on the 900 MHz band, or roughly 1000 ft in dense-urban conditions. Because it uses a self-healing wireless mesh network, data also relays through repeaters to extend coverage across larger or obstructed plants.
The hybrid D-cell-plus-supercapacitor power source delivers up to 5 years of battery life, depending on how often the sensor transmits. Battery level is reported with every transmission so you can plan replacements.
It uses a self-healing wireless mesh on your choice of 868 MHz, 900 MHz, or 2.4 GHz, with 128-bit AES encryption on the wireless link. The 868 and 900 MHz options are sub-GHz (sub-gigahertz) bands, and sub-gigahertz radio travels farther and punches through walls and machinery far better than higher-frequency Wi-Fi or Bluetooth, so the sensor keeps reporting from deep inside the plant. The mesh forms and repairs itself, relaying data around obstacles to your gateway.
Two ways: a magnetic mount for fast, tool-free placement during a survey, or a ¼”-28 UNF threaded stud for a permanent, repeatable installation. For the best high-frequency data, mount as close to the bearing housing as practical.
Yes. The sensor is sealed in an IP67-rated enclosure measuring 85 mm tall by 48 mm at the base and weighing 225 g. Its electronics carry a -40 °C to 85 °C component rating; NCD tests the assembled unit across 0 °C to 40 °C.
No. The sensor is a one-time purchase with no subscription or recurring cloud fee. Paired with an Atrium Gateway, you get dashboards, alerts, and reporting with no per-machine software charge. You own the hardware and the data it produces.
Wherever you choose. Data stays on your network with no required NCD cloud account. Through Atrium’s built-in Node-RED you can forward readings to AWS, Azure, Google Cloud, any MQTT broker, a local Modbus network, or your own REST API.
Yes. The sensor is made in the USA by National Control Devices and is RoHS compliant. Many NCD products carry a 5-year warranty, and you’ll always reach a U.S.-based engineer for support. Contact NCD to confirm coverage for your configuration.
