Itokii Vibration Meters use an accelerometer to measure g-force on 3 axis and then determine speed and frequency. They can be set to only capture when a vibration occurs and sleep when no vibrations are present, or they can be set to measure at a given assessment interval regardless of whether a vibration has occurred. If set to always measure, the sensitivity can be further adjusted to filter out noise. The Vibration Meter will also report the duty cycle, or how long the sensor was measuring vibrations throughout the heartbeat.
The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 - 3.6 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.
Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.
- Reports data as speed (mm/s) and frequency (Hz) on all three axes, and how long the sensor was measuring during the interval.
- Adjustable measurement methods: Peak acceleration RMS, peak velocity RMS, and true RMS.
