Vibration monitoring is a key aspect of gauging the safety of many equipment and structures, ranging from rotating machinery to bridges and buildings. The ALTA Advanced Vibration Meter features a configurable frequency measurement range from 0.4 Hz to 4800 Hz (24 to 288,000 rpm).

The wireless meter is a turnkey solution that uses an accelerometer to track vibration and frequency on three axes. The U.S.-manufactured sensor captures data for vibration frequency and velocity, displacement or acceleration. It also has the ability to report duty cycle as well as temperature, providing more key metrics to protect important assets and operations.

ALTA products employ Monnit's new Encrypt-RF Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again.

Integrated on-board data storage allows ALTA sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.

The standard version of this sensor is powered by two replaceable 1.5 V, AA batteries. 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 to 3.8 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.
