ALTA – Accelerometer, AA, Advanced Vibration Meter


Perfect for measuring frequency from 0.4 Hz – 4,800 Hz. Suitable for vibration monitoring, bearing monitoring, motor monitoring, vibration metering.


With industry-leading range, security & affordability, Monnit’s ALTA range of remote wireless sensors has set new benchmarks. Since their introduction in 2017, Monnit’s ALTA Sensors have been global game-changers for many industries including Food Service, Facility Management, Manufacturing, Logistics, Pharmaceutical & Medical.

This Advanced Vibration Meter (AVM) wirelessly monitors oscillation on three axes to capture vibration frequency, velocity, displacement, and acceleration. The US-made AVM also reports duty cycle and temperature, helping protect vital assets and perform end-of-life analysis.

This AVM sensor has a configurable frequency measurement range from 0.4 Hz–4,800 Hz (24 RPM–288,000 RPM) to track a subtly swaying bridge or high-RPM machinery. If a monitored variable exceeds thresholds, the AVM issues an alert via text, email, or call.

This sensor is perfect for a wide array of uses, including motors, pumps, fans, compressors, gearboxes, chillers, rollers

Using vibration analysis as a tool to determine the specific cause and location of machinery problems can expedite repairs and minimize costs. Vibration sensors can measure and analyze displacement, linear velocity, and acceleration.

Other common uses include:

  • Vibration Monitoring
  • Bearing Monitoring
  • Motor Monitoring
  • Bridge Monitoring
  • Assembly Line Monitoring
  • Vibration Metering



Our sensors have paired exclusive RF technology with industry-leading power management to achieve the best battery life in the IoT industry. While the competition lasts anywhere from six months to two years, Monnit has made 10 years battery life possible with a pair of two AA batteries.


Our sensors provide upto 4 times the range of standard competitor wireless sensors, which means you don’t need as many Gateway’s and a much wider coverage area. Our sensor has a non-line-of-sight reach of 300 meters through upto 12 walls. This is all possible due to the most advanced Frequency-Hopping Spread Spectrum (FHSS) technology that allows for superior interference immunity from other wireless devices.


The sensor has Monnit’s most secure embedded Encrypt-RF™ Security which consists of a 256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages. Security is maintained at all communication points from sensor → gateway then gateway → software, then back again.


The user-customization settings allow you to set the frequency of readings with the ability to set thresholds for alerts via SMS text and/or email.

The sensor will store as many as 3,100 time-stamped messages if communication is disrupted for any reason (power outage, network disruption … etc). Once the communication is restored all messages will be delivered in chronological order.
