Our Approach

We work closely with you to develop a tailored vibration management solution that ensures your compliance requirements are met this can also extend to operational improvement.

We start by having a conversation with you and your team to gather a comprehensive understanding of the environmental who, what, when and how factors. We work closely with you to understand which areas are of most risk, key criteria, and your monitoring objectives.

We then tailor our vibration monitoring solution to your specific requirements, factoring in the appropriate product/s, quantities, installation considerations and the right service framework to ensure the data provided to you gives you the exact data you need, when you need it, to make informed project decisions.

It might sound obvious, and in some ways it is! But it’s also an essential part of getting it right, and making sure you have access to your data at all times.

We find that the best solutions can be delivered from thorough investigation and experience, to ensure your project is delivered safely every time.

Compliance Monitoring 101...

It’s important to define what we are measuring – e.g. velocity or acceleration – and why – e.g. structural damage or human comfort.  This will begin to point us in the direction of systems.

Consider why we are  measuring.  It may be for structural damage, human comfort or both.  Here are a few standards that we may be required to report, or compare the measurement, against ( e.g. DIN 4150, AS 2187, BS 6472)

It’s critical that our settings are configured to report the appropriate data otherwise all our good effort could be undone.

We would recommend monitoring in both continuous and trigger modes.  This will give you transparence to the highest interval and trigger values during the nominated operational time table.  Let’s say all events over 5mm/s are of concern. Once trigger mode is enabled we have the ability to set a level eg 5mm/s and duration of waveform to suit the event (e.g. Rock Hammer, Piling, Roller, Blast) this will ensure we capture the entire waveform to permit us to report it against the relevant standard.

If your blast or vibration monitoring work requires or desires the ability to alert on exceedances, report, check system diagnostics, communicate, control, or manage activities in real-time..  Yes is the likely answer..

Consider the standards in line with your scope of works.  What will we be reporting against or comparing our results to. This will influence how we mount our sensor, sensor type, location between source and receiver.  When mounting will it be horizontal, vertical, down hole (sonde).. Will we secure with soil spikes, glue, dyna bolts, or other means  

Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 Hz. If it takes 1/100 of an hour, the frequency is 0.028 Hz.

Usually frequency is measured in the Hertz unit (Hz), named in honor of the 19th-century German physicist Heinrich Rudolf Hertz. For example, an “A” note on a violin string vibrates at about 440 Hz (440 vibrations per second).

frequency

When we talk about frequency in these contexts, we refer to two separate issues. The frequency of a waveform (as above) is generated by the source of vibration. However, we also use the term frequency when referring to the sample rate (or sample frequency) of the monitoring instrument. The first is generated by the source, while the second is a property of the monitoring device.

Sample rate is literally how fast samples are taken. How often that snapshot is taken represents the sample rate or sampling frequency. It’s measured in “samples per second” and is usually expressed in kiloHertz (kHz), a unit meaning 1,000 times per second. Audio CDs, for example, have a sample rate of 44.1kHz, which means that the analog signal is sampled 44,100 times per second.
