COMMUNICATIONS • TELEMETRY


Compact, multiband transceiver for industrial telemetry As well as this model, Circuit


transceiver STD-601 400 MHz, a module for telemetry and industrial applications. The design has four frequency bands under one hardware, while maintaining as close as possible, the high performance of Circuit Design’s conventional RF modules. Featuring similar performance with regards to narrowband, blocking and sensitivity, the module is suited for rugged, noisy industrial environments where good channel selectivity is a requirement. These modules are surface mountable, taking up minimal area with the relatively small height (5mm)

ircuit Design, a leading supplier of low power radio modules, recently introduced the


of the casing allowing good portability. The STD-601 includes four frequency bands conforming to various ISM


bands within a single hardware. This therefore allows frequencies to be set within a wide frequency range. As well as programmable


frequency bands and channels, the STD-601 includes a variety of selectable RF power levels (maximum 50mW RF power) and data rates. User data input is transparent allowing the use of proprietary protocol.


Design also provides an identical module, the single band 434MHz version, which has CE EN300220 approval with low consumption current of 26mA


(TX 10mW, 3V). Applications


include remote control of industrial equipment and industrial telemetry in a


variety of sectors. l For more information ✔ at www.engineerlive.com/iog

Remote broadband technology deployed The nCentric technology can be


provided between rigs and vessels and onshore facilities, following a deal between two key players in the sector. Ashtead Technology, an independent provider of subsea equipment rental, sales and services to the offshore industry, secured the worldwide agreement with nCentric. The deal sees Ashtead Technology supplying video streaming and data transmissions for large-scale, wireless dynamic mesh networks from its offices across the globe. Tim Sheehan, commercial director

at Ashtead Technology says: “Capturing data from remote locations is still a major challenge for the industry. Today, most communications from oil and gas platforms and vessels to shore depend on expensive satellite links. The nCentric technology delivers a cost effective, efficient and reliable wireless network in large, hard- to-reach geographical areas.”

ast, reliable and more cost-effective broadband communications is now being


used to monitor offshore operations, increase communication and can relay high definition footage from remotely operated vehicles (ROVs) in real- time. The system can be configured remotely and can be monitored from an onshore location, reducing the number of people required offshore and limiting downtime. The technology was a key


component in the clean-up operation following the Deep Water Horizon disaster in 2010. By using nCentric’s communication node on board eight vessels, crews were able to stream more than 10 live ROV video images to the offshore command centre as well as between one another and create a reliable communication link.


Sheehan adds: “The wireless communication allows operators to track vessel movements. The system can be quickly and easily installed, unlike traditional cable networks, which can be expensive and in some cases impossible.

“Harsh offshore conditions combined with remote and isolated locations means that communication lifelines are increasingly important to manage fleet and vessel operations as well as maintain crew safety. The need to implement secure, fast and reliable communications systems to monitor activity and track production is a vital part of any offshore operation.” Headquartered in Belgium, nCentric


is a fast-growing provider of offshore network solutions to support offshore communication. l
