Gas Detection 21 Gas Control Panel Now SIL 3 Approved
Galileo SMS gas control panel from Sensitron (Italy) has been designed and approved to comply with the SIL (Safety Integrity Level) requirements according to the European Standard EN50402 on Functional Safety and has reached the SIL 3-C Level. Extremely flexible and highly reliable, it allows monitoring gas detectors connected with both 4-20 mA transmission and on addressable loops. The functional safety is aimed to supervise and manage the behaviour of a system in case of failures. When defining the system structure all possible different types of failures that may occur in any part of the system are to be considered and evaluated.
The control unit’s main board is designed around 2 powerful microprocessors, that communicate one to each other the monitored data ensuring the complete availability of all main
board functions even in the case of a failure in one microprocessor. A broad range of self-testing facilities are implemented to detect and localize possible faults. The redundancy offered by every module being part of the system, added the possibility to communicate with remote input/output modules via a redundant BUS and with each detector via double connection (analogue and addressable), makes this system comply with the Functional Safety requirements of EN 50402 up to SIL3. The range is also completed by the GALILEO S 8 that has been designed for small systems up to 8 analog detectors and the GALILEO S 32 where up to 32 detectors are connected on an addressable closed loop.

Latest Developments in PID, SF6 and Corrosion Monitoring
Ion Science (UK) enjoyed recent success at ACHEMA, the show provided the ideal platform for Ion Science to showcase its new GasClam instrument and latest developments in PID, SF6 and corrosion monitoring.
Launched for the first time was the new GasClam, the world's first and only in-situ borehole gas monitor
for the detection of methane (CH4), oxygen (O2), and carbon dioxide (CO2), with optional sensors for carbon monoxide (CO) and VOCs, plus water depth.
GasClam can be used for most below ground applications, continuously, for up to three months to measure gases with temperature, barometric and borehole pressure giving a true long term profile - the only instrument of its kind to do so.
Also on display was the newly developed, battery powered Hydrosteel Transportable monitor, a totally non-intrusive device enabling continuous monitoring of hydrogen flux to identify and confirm control of corrosion and hydrogen crack risk.
Additional exhibits included the SF6 P1 and LeakCheck P1:p, a revolution in SF6 leak detection, ensuring incredibly
fast searching at ultra sensitive levels, and the leading range of PID detectors for accurate detection of VOCs, from ppb to ppm levels.
Duncan Johns, Managing Director for Ion Science states: "We were impressed with the high number of visitors attending this year’s event, despite the current economic climate. The show was upbeat and busy and provided us with an ideal opportunity meet with a number of our European distributors and to give hands-on demonstrations of our new GasClam instrument, and world leading range of PID, SF6 leak detectors and corrosion monitoring equipment. We would like to thank all those that attended.”

Photovac (USA) is pleased to introduce the PetroPRO for the detection of BTEX compounds.
The measurement of BTEX compounds (benzene, toluene, ethylbenzene and xylene) is critical to maintain compliance with environ- mental and occupational health and safety regulations. The intrinsically safe PetroPRO provides real-time measurements and, with its gas chromatography-based technology, the PetroPRO offers unsurpassed accuracy with the lowest detection limits available in a portable instrument.
The PetroPRO is exceptionally easy to operate, thereby minimising training time for your technicians. With the simple push of a button, the PetroPRO runs through the BTEX analysis and provides quick results. And, it does not require costly filter tubes, thereby reducing operating costs. It also stores data for subsequent download to a computer for documentation and recordkeeping.
