Vibration Monitor Guide

The AVA-M80 is a vibration measurement device which is intended for use in situations where you need reliable noise measurements with the minimum amount of effort according to BS-5228-2 & BS-7385.

Weight: 6 kg

Dimensions: 30 x 20 x 15 cm

Local Measurement Data

Data saves internally to the monitor and once a cloud connection is established, the data is sent and processed in our cloud system to give you real-time access and alerts via SMS and Email depending on the user preferences. This happens once every 24 hours to save the battery, which is an incredible 8 months! But don’t worry, if you get a breach, you’ll see all the data immediately with the alerts.

The unit can be setup to measure PPV in all three tri-axial directions. The unit can log in 1 minute intervals up to 24 hours. Frequency waveforms and dominated frequency can be collected on a device enabled with the frequency option. Audio samples can be captured on the device and uploaded to the AVA net cloud for Identification with customisable trigger settings available, to be configured remotely from any where, any time.

Enable low power mode and go longer with special configuration of the settings.

Cloud Based Login

You can login to your Sonitus Cloud portal anytime to access your noise monitor and download your readings. Visit app.sonitussystems.com

Calibration

The unit requires calibration once every two years in our UKAS accredited laboratory. The system utilises a robust geophone which maximises the calibration interval and ensures reliable data.

Power

The monitor will accept mains power or battery power. It can run for up to 72 weeks from 6 no. of D-cell batteries available at your local supermarket.

How to change the batteries?

1. Hold START/STOP to stop the measurement.
2. Ensure DATA PROCESSING light is OFF before proceeding.
3. Open the battery compartment by twisting the locks.
4. Pull out black battery holder and replace 6 x D-Cell batteries, making sure the batteries are the correct way up.
​5. Once batteries are replaced and compartment is closed, press START/STOP once to restart measurement.

Mounting & Fixing Options

The vibration monitor can be mounted easily outdoors using its weather protected enclosure. For example it can be mounted on a hoarding, wall or ground easily and quickly.

Wall Mounting

Tools Required

• Metric set of Allen keys
• Adjustable spanner
• Battery operated drill with an 8mm masonry drill bit for the wall plug where required. 
• Padlock to secure the monitor in the locking clamp
• Zip ties to tidy up the loose cables

Ground

Tools Required

• Metric set of Allen keys
• Adjustable spanner
• Battery operated drill with an 8mm masonry drill bit for the wall plug where required. 
• Padlock to secure the monitor in the locking clamp
• Zip ties to tidy up the loose cables  

Secure the geophone to the base plate using the allen head screw supplied.

Attach the base pins to the bottom of the floor plate to ensure a stable mounting. Level the sensor.

Cable Connections

Match the colour cables in this order.

(T)ransverse = Red
(V)ertical = Black
(L)ongitudinal = Green

Sensor Types

We have a two types of sensors, but both operate in a similar way. Just pay attention to the direction of mounting. With the gold plate sensor this should be mounted with the gold plate to the top of the sensor.

For the block sensor with single cable outlet, note the arrow in the direction of the source of vibration and ensure the spirt level faces upward to the sky.

Security

Use the supplied security locking clamp bracket to by installing 3 screws with washers and wall plugs to the mounting point and a padlock to secure the device.

Ground Mounted Noise Monitor

When installing your vibration monitor aim to install it on the building which is sensitive to vibration and to be protection. Ensure the unit is installed no more than 0.5m from the ground for the first monitoring position and ensure it is installed on a solid base or structure, do not fix the unit to wood or flexible materials. A wall would be ideal.
