Oil & gas
gas detectors provide protection in extreme environments
Seeing through the eyeS of the mobile worker
cooperation partner Iristick, has introduced Visor-Ex 01 smart glasses for industrial use in hazardous areas. The intelligent wearable,
T
weighing just 180g, combines high camera / display quality and reliable communication features in an ergonomic design for user’s utmost comfort. This provides mobile workers with an optimal companion for tasks that require hands-free use as well as continuous communication, for example with remote expert support. A total of three integrated cameras transform Visor-Ex 01 into the remote expert’s bionic eye. Two 16-megapixel cameras are centrally positioned to depict the wearer’s natural field of vision – this way remote support
he Pepperl+Fuchs brand ECOM Instruments, together with its
downtime by offering performance reliability over wide areas in extreme environments and an easier, faster installation and commissioning process. Extreme environments include both heavy vibration conditions and operating temperatures ranging from -55°C up to 65°C degrees commonly found in the oil and gas, refining, chemical, mining and large-scale refrigeration system operations. The Rosemount 935 Open Path Combustible Gas
E
Detector uses infrared technology to detect a wide range of highly combustible hydrocarbon gases, including methane, propane and ethylene. In the oil and gas industry alone, 22 per cent of all fatalities come from explosions (combustion or fire) and exposure to hazardous gases, according to the latest statistics from the CDC’s (Centers for Disease Control and Prevention) National Institute for Occupational Safety and Health. The Rosemount 936 Open Path Toxic Gas Detector
views what is happening from the same angle and perspective as the mobile worker. A secondary camera offers a 6x optical zoom for zooming without loss of quality and scanning of barcodes and QR codes. The system utilises the ECOM Smart-Ex
02 smartphone for hazardous areas as a computing unit with LTE connectivity and a pocket unit with a replaceable battery for power supply, an intelligent ecosystem is created for a wide range of application scenarios in the industrial sector. The distribution of functions across the individual system components helps to minimise the weight of the headset unit - without compromising on performance, connectivity or battery life. By connecting to the Smart- Ex 02, users can continue to use their tried-and-tested smartphone for harsh environmental conditions without restriction and benefit from all the advantages and security features and controls of the Android 11 operating system, including over-the-air updates, ease of use and TCO. Visor-Ex 01 is certified for ATEX/IECEx
Zone 1/21 and 2/22 as well as NEC/CEC Division 1 and 2 and has protection class IP68. It can be used within a temperature range of -20°C to +60°C.

uses ultraviolet technology to detect hydrogen sulphide and ammonia, two of the most common toxic gases in industrial facilities. The US Occupational Safety and Health Administration considers hydrogen sulphide immediately dangerous to life and health at 100 ppm. Ammonia irritates skin, eyes, nose and the respiratory tract at 130 ppm.
Both gases are fatal after exposure
at certain levels. Leveraging xenon flash technology,
the Rosemount 936 enables greater installation flexibility versus the
tunable diode laser (TDL) technology which needs perfect alignment between beam and receiver for high reliability. With nearly twice the tolerance for misalignment than TDL, users can save up to 30 per cent of installation time and streamline project schedules. Open path detection technology uses a source and a
detector. The source sends a modulated light beam across the monitored space, and the detector senses the amount of light absorbed by the presence of gas. This approach provides a high degree of coverage across wide areas up to 200 metres in length with accurate measurement, even if the toxic or combustible gas cloud is drifting at any point between the devices or when 95 per cent of the light beam is obscured by fog, rain or smog. The system also will alert if the path is blocked completely by a physical obstruction. The Rosemount 935 and 936 Open Path Gas
Detectors can be used in combination with Emerson’s full portfolio of flame and gas detection products as part of a comprehensive safety system to ensure quick and positive detection. Many facilities benefit from the use of multiple technologies to achieve maximum protection.
