6 Gas Detection


New Infrared Sensor Now Available for SF6, CO2


, HC or CO Measurement


Sensors Europe GmbH, a German OEM gas bench manufacturer with more than 40 years of experience in infrared gas sensing, is pleased to announce its new Gasmitter product line. Gasmitter is also available for Sulphur Hexafl uoride measurement in range of 0-1000 ppm for gas leakage detection or in range of 0-100 Vol.-% for Sulphur Hexafl uoride fi ll level measurement.Gasmitter’s smart averaging fi lter enables a quick measurement for leakage detection while a stable signal is given for fi ll level measurement. Gasmitter comes along with a linear signal output (4-20mA analogue & RS232 digital), a temperature- and pressure compensation as a standard (0-50°C and 800-1200mbar). Its size is minimised to 160mm x 50 mm to enable integration in a wide range of analysers and handheld applications.


“Fit and Forget” Four-Gas, Portable Monitor with Two-Year Runtime Introduced

Honeywell has recently announced the BW Clip4, a new four-gas, portable monitor that once turned on can operate continuously for two years without the need to change sensors or charge batteries, helping customers boost safety compliance and reduce maintenance costs.


Ideal for oil and gas, wastewater, heavy manufacturing, confi ned space and other applications, BW Clip4 signifi cantly reduces maintenance costs associated with fl eets of portable gas detectors by eliminating repair work and the need to stock additional sensors and spare units. Because it’s always on, the BW Clip4 helps drive safety compliance by assuring that workers wearing the device are protected.

“The BW Clip4 operates on a fi t and forget cycle—simply turn it on once and replace the detector two years later when the unit prompts you to do so,” said Ken Schmidt, VP/General manager for Honeywell Industrial Safety. “It offers a whole new combination of benefi ts in multi-gas detection that haven’t been possible until now: two years of battery runtime without re- charging or changing batteries, small size and ease-of-use, the functionality of a multi-gas detector, and improved safety compliance.”


Using non-dispersive infrared (NDIR) technology, previously available only in fi xed-gas detectors from Honeywell Analytics, the BW Clip4 consumes 1,000-times less battery power than a catalytic bead (pellistor) sensor, the traditional technology used to detect fl ammable gases in a portable device.


Other features include: Simultaneous monitoring of H2 S, CO, O2 and combustibles (LEL); Real-time display for instant gas readings even in non-alarm


conditions, along with current gas concentration level and changes in atmospheric conditions; Simplifi es fl eet management by generating record and compliance reports automatically (using Honeywell Intellidox instrument management system); and Internal test function reduces downtime by tracking battery life and alerting users when the battery is ready for replacement.

Gas Imaging Camera for ATEX Zone 2 Locations


The GFx320 Optical Gas Imaging (OGI) camera from FLIR Systems combines proven, innovative technology with the assurance of third-party certifi cation for use inside ATEX Zone 2 (Class I, Div. II) hazardous locations.


With new stricter global standards for methane emissions, there is a growing need for faster, safer, and more reliable methods to locate and repair hydrocarbon leaks across the oil and natural industry. FLIR Systems, has addressed that need with its intrinsically safe OGI camera - the GFx320. Through thoughtful design the GFx320 meets sensitivity standards such as those defi ned in US EPA’s new OOOOa methane rule. Benefi cially it also automatically tags fi les with the GPS data often required for regulatory reporting.


Independent testing of the GFx320 to demonstrate compliance with the EPA’s NSPS 40 CFR part 60, subpart OOOOa sensitivity standard for optical gas imaging equipment was performed by the UK National Physical Laboratory (NPL). In these tests, the NPL confi rmed that the FLIR GFx320 optical gas imaging camera is capable of imaging a gas that is half methane/ half propane at a concentration of 10,000 ppm at a fl ow rate of less than or equal to 60g/hr from a quarter inch diameter orifi ce.


We make a whole world of sense.


At Alphasense we are pledged to produce the safest, most reliable gas sensors in the world.


Every product is exhaustively tested and we consistently have the lowest warranty returns in our industry.


So ask yourself: Would it really make sense to buy anything else?


The GFx320 optical gas imaging camera is capable of imaging a wide array of gas compounds, but was specifi cally designed to see the following hydrocarbons: Methane, Benzene, Propane, Butane, Ethane, Ethanol, Ethylbenzene, Ethylene, Heptane, Hexane, Isoprene, MEK, Methanol, MIBK, Octane, Pentane, Propylene, Toluene, Xylene and1-Pentene.
