8 Gas Detection
WWEM 2012 to Feature Gas Detection Zone
Break Through Confined Space Monitor, Purge and Barhole Tester
RKI (Germany) have announced the release of their latest advancement in portable instrumentation, the Model GX-2012. This version has advanced design features for general industrial confined space entry as well as enhanced capabilities for purge and barhole testing for pipeline companies and gas utilities. This model succeeds the Model GX-2003, with improved datalogging capabilities, rugged IP-66 weather protection, and louder more visible alarm indicators.
Built around high-quality micro-sensor technology, the GX-2012 is RKI's smallest personal 5 sensor gas monitor with a built in sample pump. Weighing only 12 ounces, it has many features, which set the GX- 2012 apart from the competition. For example, it can monitor the standard confined space gases (LEL combustibles, Oxygen deficiency, Carbon Monoxide, and Hydrogen Sulfide), and it can also measure 100% volume Methane while dynamically displaying either % LEL or % volume with its auto- ranging ability.
The organisers of WWEM 2012, the Water Wastewater & Environmental Monitoring event (Telford, 7/8th November 2012), have announced that this year’s show will again feature a Gas Detection Zone following the popularity of this section at the last WWEM in 2010.
The Council of Gas Detection and Environmental Monitoring (CoGDEM) is helping to organise the gas detection zone which will focus on new technology and products to detect hazards such as exposure to low oxygen levels in confined spaces and to toxic and flammable gases in the workplace. CoGDEM’s Leigh Greenham says “This year there will be more stands featuring gas detection technology as well as hazardous area (Ex) products, in addition to a wider range of free workshops covering topics such as ‘bump-testing versus calibration’, ‘confined space entry’, ‘VOC detection’ and much more.”
New gas detection techniques will be on show and the new ‘CoGDEM Guide to Gas Detection’ hardback book will be launched at the event. Many of the world's leading gas detection experts' products and services will be on display at the WWEM 2012 exhibition, including Air Products, BOC/Linde, Crowcon, Draeger, GMI, GfG, ISC, Infratec, Scientific & Technical Gases and Sira.
WWEM organiser Marcus Pattison is delighted with CoGDEM’s participation. He says: “With so much taking place during the two days, WWEM 2012 will be a hive of frenetic activity, but with free entry, free parking and free lunches and refreshments for pre-registered visitors, we have tried to remove as much of the stress, hassle and cost associated with other events.”

The GX-2012's large LCD display shows all gas readings, battery level, current time, and will automatically backlight in alarm conditions. Other standard alarm types include vibration, visual, and audible alarms that can be set to latching or non-latching. Controlled by a microprocessor, the GX-2012 continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors. The GX-2012 can interchangeably operate on either a Li-Ion battery pack or 3 AA alkaline battery pack. The Li-Ion battery pack can receive a charge directly within the instrument or separately, allowing the unit to remain in service.
Programmed calibration and bump test intervals and reminders are user adjustable and can be set to either go into alarm or to lock the user out of normal measurement mode once a calibration period has expired. Calibrations can be performed automatically or individually in single calibration mode. The GX-2012 is also compatible with the economical SM-2012 single channel calibration station.

Honeywell (UK) announces that it has acquired Fire Sentry Corporation, a privately-held manufacturer of innovative fire detection and control products for a broad range of industrial markets. The terms of the transaction were not disclosed.
Based in Yorba Linda, California, Fire Sentry’s product portfolio consists of fast-responding electro-optical flame detectors, portable test lamps and dedicated control panels that are used by customers in industrial settings such as petrochemical, semiconductor, paint booth/finishing, automobile airbags and munitions plants. Fire Sentry’s products are designed to ensure rapid, accurate, and reliable detection of both hydrocarbon and non-hydrocarbon fires within a single device.
The acquisition will help Honeywell significantly expand its gas and flame detection, and monitoring solutions and builds on the company’s acquisitions of System Sensor in 1984 and Zellweger Analytics in 2005 among other important acquisitions in the gas detection arena. The company will be integrated into Honeywell Life Safety and will extend significant synergies in distribution channels, vertical end-markets and global end-users.
“This acquisition will further strengthen Honeywell’s leadership position in the gas detection space by enhancing our competitive gas and flame offering and bolstering our cross-selling opportunities across the globe,” said Mark Levy, president and CEO of Honeywell Life Safety. “Fire Sentry has a 30-year history of proven fire and flame detection innovation and more than 100,000 units installed worldwide in a wide array of industrial settings. This is a great fit for our Life Safety business and deeply complements our technology advances in gas detection which include an impressive number of technological firsts.”
Fire Sentry’s smart electro-optical radiant energy multi-spectrum and multi-spectral flame detectors and associated products greatly reduce false alarms thanks to its innovative use of patented algorithms.

Ultrasonic Gas Leak Detector Features HART Communications Protocol
The Gassonic Observer-H Ultrasonic Gas Leak Detector from General Monitors (USA) is ideal for gas leak detection in pressurized systems. The new Gassonic Observer-H features HART communications, Modbus with single and block transfer modes, Emerson AMS Intelligent Device Manager support, and event logging. The Observer-H is ATEX, IECEx, FM and CSA hazardous area certified and SIL 3 suitable.
The Gassonic Observer-H detects gas leaks by sensing the airborne ultrasound emitted from leaking gas at high pressure. It is suitable for gas detection in open, well-ventilated areas, where traditional detection methods may be unsuitable or dependent on ventilation. Since the gas leak detector responds to the source of a gas release rather than the dispersed gas, it is unaffected by changing wind directions, gas dilution, and the direction of the leak. The Gassonic Observer-H’s wide coverage zone makes it possible to supervise areas up to a 20 meter radius, for the detection of leaks as small as 0.1 kg/sec., with only one device.
Rugged and designed for failsafe operation, the Gassonic Observer-H features robust microphone technology with an advanced stainless steel microphone. The detector also offers the Senssonic™ integrated acoustic self-test, which verifies the integrity of the instrument’s electric circuit and microphone every 15 minutes. It features stainless steel, AISI 316L explosion-proof housing, offering corrosion resistance in the harshest environments.
Offices in the UK, USA, Saudi Arabia, Mexico and Shanghai
The Gassonic Observer-H features a sophisticated high pass filter to remove frequencies below 25 kHz, effectively eliminating interference from audible sound. At the same time, setting the alarm trigger level above the ultrasonic background noise ensures the detector accurately detects gas leaks. The Observer-H is equipped with a 3-digit LED display and an event logging function that stores fault, sound check, calibration, and alarm event history.
The versatile Gassonic Observer-H can be configured with an analog output or Modbus or HART communications to provide complete status and control capability in the control room. The Modbus and HART data can also be used for predictive maintenance and to enable asset management and process improvement.
