Portable / Field Testing 53 The Pipe Locating Device You Have Been Looking For


If you’re looking for a precise, reliable and versatile pipe locating device, Sewerin’s (Germany) new UT 830 is the one for you: no matter where you’re working or how diffi cult the conditions, the 83 kHz frequency is perfect for actively locating underground gas and water pipes.


The UT 830 can also be used to passively detect power and cathodic-protected lines. Exclusive technical functions provide fast, accurate and reliable results. The high protection class, robust construction and easy operation make the UT 830 your perfect companion on virtually every pipe location task.


With its IP65 protection class, extremely robust construction and compact size, the UT 830 is ideal for all working and weather conditions, even in diffi cult environments.


The UT 830 proves particularly versatile, for example in the building trade, thanks to its ability to passively locate power and cathodic-protected lines. 50 Hz, 100 Hz and 150 Hz frequencies are available for this.


Exceptionally long operating times of 75 hours for the receiver and up to 150 hours for the transmitter guarantee maximum availability and minimum downtime.


Thanks to its adaptive fi ltering, the UT 830 offers impressive response times. The extremely quick and reliable directional arrow display means that pipes can be located in very tight and precise location corridors. This directional arrow indicates the location of the pipe in relation to the position of the user, thus guaranteeing accurate results, irrespective of operating mode or operating style.


The unique PEAK function verifi es the location results immediately. Surrounding pipes also energised because of the high frequency can be easily hidden from view at the touch of a button. This prevents measurement errors and the unintentional location of parallel pipes.


Fully automatic depth measurement guarantees an accurate overview of the pipe position at all times. Thanks to the special internal positioning of the aerials, locating main pipes and branches is child’s play.


Its high location frequency of 83 kHz means that the UT 830 can pinpoint underground gas and water pipelines beyond insulated connection points – even with long pipes and weak signals. The signal allows you to track the pipe, even beyond several sleeves and connection points that would otherwise present signifi cant resistance for a lower frequency.


Thanks to its easy and self-explanatory operation on just one frequency, even less experienced users quickly and intuitively get to grips with the UT 830 without extensive training. Visual and acoustic signals provide feedback, facilitate progress and inspire confi dence in the location results.

A Powerful Solution for Monitoring Soil Water Profi les


For More Info, email: email:


The PR2 Profi le Probe, from Delta T Devices (UK), offers a highly convenient single instrument solution for accurate and concurrent measurement of soil water content at various depths down to one metre. The system offers two lengths of probe; the PR2/4, measuring at 4 depths down to 40 cm, or the PR2/6 measuring at 6 depths down to 100 cm. The PR2 system generates volumetric moisture content values at each of the sensor positions along the length of the Profi le Probe.


The PR2 is built around patented sensing technology which provides research grade performance in all soil types - offering low salinity and temperature sensitivity. Installation is via a bespoke access tube - which is inserted into a pre-augered 27mm diameter hole in the soil. This results in minimal soil disturbance. Customised augering equipment is available to optimise installation.


The PR2 can be used in both portable and long term installation applications. A hand- held readout unit enables instant readings at multiple locations with a single probe. Alternatively, a PR2 can be permanently installed for continuous monitoring with a data logger (such as the GP2 Data Logger and Controller).


The PR2 Profi le Probe is a powerful research grade tool that can generate large amounts of accurate information quickly and easily. As such it has proved to have a wide range of applications in academic and industrial environments, from crop water balance and catchment scale studies to geotechnical, forest and viticulture applications. It has even been used to monitor relative changes in moisture content in stone walls.


The PR2 is small, lightweight, portable, and easy to use. It also has a unique ability to test the quality of the installation against the presence of stones or voids next to a sensor. This gives the operator the choice to re-site the access tube and probe if needed - to achieve optimum measuring conditions. Combined, these attributes have made the PR2 a fi rst choice for many researchers who are looking for a reliable fi eld-proven solution.

Wireless Temperature Monitoring Probe for Composting and Biomass Plants


Accurate temperature monitoring in composting windrows is essential to ensure an effi cient process and abiding local regulations. Permanent transmission of data from a wireless autonomous device to a centralised location allows continual recording and logging, improving effi ciency and reducing the time needed to complete a composting cycle. Using wireless devices increases workplace safety by eliminating running wires, as well as need for the operator to manually control the temperature several times a week by climbing on the piles.


Banner Engineering (Belgium) has developed a fi eld proven wireless temperature monitoring probe that is used in in composting and biomass plants over Europe. Designed for rough conditions, high temperature and humidity, the battery operated module has three sensors to accurately monitor the temperature gradient inside the windrow. Powerful electronics provide a strong wireless signal, and the stainless steel construction guarantees its durability.
