We recently enjoyed a flying visit to Tollo in Italy to put the finishing touches to a PL3000/CFA system installed by Soil-Tek to one of their S60 piling rigs.

In addition to the standard range of NDT CFA sensors, the system was supplied with optional wireless concrete pressure sensing and an integrated mast inclinometer.

The rig is now heading for a customer in Australia and, with the benefit of NDT's high speed two-way remote data link, its performance on job sites can be monitored remotely from our base in the UK.

The cellular data link will also allow the rig's computer to be uploaded remotely with detailed piling schedules, CFA construction profiles, new software and any changes to rig or auger configuration with no requirement for an engineer to visit site.

CFA rigs with auger extensions and wired concrete pressure sensors require a recoil drum to allow the rotary table to move independently of the rotary table whilst maintaining a signal from the sensor.

How often do you need to replace a drum where the cable has been overstretched, or caught / snagged and damaged the recoil mechanism ? How much down time is caused ? How much extra concrete have you used whilst the pressure sensor was not working ?

With NDT's innovative wireless concrete pressure sensor, expensive recoil drums and cumbersome cable extensions become a thing of the past.

The wireless sensors fit into a standard NDT pipe boss and are simple to incorporate into existing NDT systems. Very low powered electronics and high capacity batteries ensure the sensors can be used for up to 2 years before a battery change is required.

Having a working concrete pressure sensor is vital for rig operators to confidently extract to lower oversupply targets. In turn, this can significantly reduce your excess concrete volumes which means a wireless concrete sensor upgrade could pay for itself in a matter of days.
