- Vertical - ± 30º from vertical
- Standard cable reel lengths are 30, 50, 75, 100, 125, 150m (other lengths available on request)
- The cable weighs 5.8kg per 100 metre.
Our Inclinometer system measures tilt using MEMS sensors, the technology which has become the standard technology within the industry.
The benefits of MEMS sensors are that they offer faster more rugged systems than the old servo-accelerometer systems and are virtually unaffected by temperature.
Lightweight & rugged
The lightweight but rugged construction of all components means that a 100m system can easily be carried by one person.
Data from the probe is transferred from the reel by Bluetooth connection to the handheld data recorder.
On-board probe calibration
Calibration is embedded into the MEMS conditioning board in the probe which means that only the probe itself needs to be returned for re-calibration or calibration check unlike a system where the probe is attached to the reel where the complete system has to be re-calibrated. This has a significant saving on delivery costs especially from overseas.
Any probe can be used with any cable reel and any handheld data recorder so that if you have an existing 50 metre system and now need a 100 metre system you only need to buy another cable and reel as you can use your existing probe and hand-held data recorder.
The spiral probe can also be used with any reel and hand-held data recorder.
Data visual at the borehole
The Android Smart Device (ASD) allows data sets to be viewed and compared at the borehole.
It is always recommended to use the cable gate supplied with the system as it not only protects the cable from damage but also provides the most accurate and repeatable readings.
On installations deeper than 40 metres it is recommended to carry out a spiral survey using a spiral probe. The data can then be input into software to correct any spiral effects
Basic operation tips
The A axis is defined as the direction of expected movement. If it has not already been done, identify the A axis on the casing and clearly mark it.
Always fit the cable gate onto the top of the casing.
Take the first set of readings is taken in the A+ direction. This is the orientation of the casing groove into which the leading wheel of the inclinometer probe is located.
Lower the probe to the bottom of the casing and allow it to stabilise for a few minutes.
Raise the probe at 500mm intervals resting the cable grips in the cable gate each time.
The readout has a visual stability scale on the left of the screen. Once the scale shows maximum stability the reading should then be confirmed on the Android Smart Device (ASD).
Once the probe has reached the top remove it from the groove and rotate it 180º and lower again to the base of the casing and repeat the survey.
Getting the data from your Inclinometer
Data is stored within the Android Smart Device (ASD) in a simple CSV format which can either be manipulated using Excel or imported into software.
Verifying your results
Checksums can be viewed on the Android Smart Device (ASD) during the survey so that the quality of the data can be verified.
Do I need to use the same probe to survey the same hole?
We believe in being realistic and practical about the levels of accuracy that should be expected and can be achieved on a working construction site. Although every Inclinometer probe leaves the factory with the same accuracy specifications they are unique and acquire individual characteristics over time as a result of many factors.
Therefore we would concede to get the “perfect” results it would be “ideal” to use the same probe. However since this isn’t always possible especially if they are hired so we support the practice of using different probes but having consistency in the taking of the readings.
Problems connecting to the probe
There could be a few reasons why you are unable to connect, we would advise the following steps to investigate the problem:
- Check the connection between the cable and probe.
- Check there is a blue flashing light on the reel – if the light isn’t flashing press the button on the reel.
- If after pressing the button no light shows remove the battery cover and ensure the battery is the right way round (they are shipped with them back to front to avoid power usage during shipping)
- Try swapping or charging the battery.
Battery life of the system
The Android Smart Device (ASD) offers up to 35 hours talk time and the reel can be used for a minimum 15 hours continuous.
Compatibility with other manufacturers casing
The probe can be used with casing from all other manufactures, from 48mm to 85mm.
Taking care of the probe
The inclinometer probe is a sensitive measuring instrument. Handle it with care.
Lubricate the wheels regularly. Spray a small amount of lubricant or place a drop of oil on both sides of the wheel bearings. Check that the wheels turn smoothly.
Taking care of the cable
Since the cable acts to send the signal it is a very important component of the system. However it can be vulnerable to excessive twisting, knotting and kinking and should be treated with care.
To avoid these types of issues with your cable ensure you remove the probe before winding it back onto the reel after the survey is completed and remove any kinks immediately.
Never allow the probe to free fall or run quickly down the borehole by letting the cable slip through your hands. Feed the cable down with your hands or reel it off the cable reel slowly.
Any sudden stopping of the probe when lowering it down will cause high torsion within the cable and if done repeatedly will eventually cause damage to the cable.
