CONTROL SYSTEMS + AUTOMATION

Farms increase safety and productivity through asset tracking

into all aspects of the operation. “BEAMS provides an effective asset management solution that will allow farming operations to feel secure in the control of their assets,” Lourens explains. Enquiries: Anton Lourens. Email anton@ booyco-electronics.co.za

With workers and machines occupying the same working area in busy farming opera- tions, Proximity Detection Systems (PDSs) are becoming vital tools to promote safety and productivity. According to Anton Lourens, managing director of PDS supplier Booyco Electron- ics , the technology allows for intervention where a potentially dangerous situation exists between a pedestrian and a machine like a tractor. Essentially, the PDS is a sensing device that detects the presence of an object, an interface that provides an audible and/or visual alarm to the equipment operator, and wiring between the two. Both the vehicle operator and the pe- destrian can then be warned of potential collisions and danger. Warning zones are stable and predictable, and can be adjusted

to suit the specific agricultural application and standardised to particular equipment. In addition to avoiding accidents on a site, the data from the PDS can be analysed for patterns, allowing farm managers to identify unsafe behaviour and design an appropriate intervention. In terms of productivity, monitoring of machine movements by the PDS can also help managers to make better use of equip- ment at work, for instance by optimising cycle times. Linking the proximity detection hardware products and the monitoring devices is Booyco’s Electronics Asset Management System (BEAMS) – a web-based applica- tion used on a robust database. BEAMS is essentially a central information hub, and provides a reliable single source of informa- tion that can be leveraged for greater insight

Concentration measurement technology bolsters flow portfolio

Group’s international sales structures. In addition, plans are in place to eventually combine the technology direct with Endress+Hauser’s flow instruments. Innovative technology The systems from SensAction measure the concentration of liquids with the help of surface acoustic waves, which are high frequency sound waves whose behavior can be compared to seismic waves created by earthquakes. By analysing the transmission time and

Endress+Hauser has acquired SensAction AG, a manufacturer of innovative systems for measuring the concentration of liquids.With this move, the Switzerland-based Group intends to strengthen its quality measurement portfolio. SensAction will remain headquar- tered in Coburg, Germany and will keep their current staff. SensAction will operate as a division of the Endress+Hauser Cen- tre of Competence for flowmeasurement technology headquartered in Reinach, Switzerland. “This innovative technology is an excellent fit with our modern flow measurement portfolio,” says Dr Bernd- Josef Schäfer, Managing Director of Endress+Hauser Flowtec AG. “It allows us to further expand our range of products for measuring quality parameters.” Coriolis flow measurement devices from Endress+Hauser can already determine not only mass flow, but density as well. Elec- tromagnetic instruments are capable of measuring conductivity parallel to the volume flow. “These physical analysis parameters create direct value-add for the customer,” emphasises Bernd-Josef Schäfer. Endress+Hauser plans to integrate the SensAction instru- ments into its own program and open up new markets via the

amplitude, the acoustic parameters of the liq- uid, such as sound wave velocity, impedance and density, can be meas- ured in order to quickly and precisely determine the concentration. Be- cause they contain no moving parts, the sys- tems are maintenance- free and do not suffer from wear-and-tear.

Apart from developing and manufacturing concentration meas- urement systems, SensAction also offers supplementary services, such as software products that rely on a laboratory measurement to provide a high degree of accuracy and user-friendliness for the customers’ applications. The key fields of application for the SensAction instruments include concentration measurements for liquid process media. The acquisition of SensAction will be effective retroactively from 1 January 2017. Both parties have agreed to not disclose the details of the transaction. Stefan Rothballer and Michael Münch, two of SensAction’s founders, will continue to manage the innovative company’s business.
