Monitors for Zones 1, 2, 21 and 22 K Controls has recently launched its new 07-100 and 007-120 Exd IIC Position Monitors that are ATEX and IECEx certified for use in gas Zones 1 and 2 and dust Zones 21 and 22.
The CE marked, IP67 enclosures are supplied in either coated alu- minium or ANC 4B (316) stainless steel. The products have been designed to accommodate, as an option, the latest version of the top mounted highly visible Klearvision position indica- tor that can be used in IIC hazardous areas.
The 007-100 (pictured) is a compact solution that can contain up to two switches or a 4- 20mA position trans- mitter. The larger 007-120 can contain up to four switches and a 4-20mA posi- tion transmitter.
Designed for use in the oil and gas and petrochemical industries, both units can be fitted to a range of quarter turn or linear valve actu- ators. There is also an extensive

range of monitoring equipment that can be fitted in this new range of Exd IIC Position Monitors. Switch options include micro- switches, hermetically sealed magnetically operated reed switches and standard or failsafe inductive proximity sensors. Potentiometers of various different values can be geared or directly driven. A solenoid back wiring facility can be provided so that switches and solenoid can be wired to the control room via a single multi-core cable without the requirement for a separate junction box. For continuous feedback of valve posi- tion or for monitor- ing the performance of critical emer- gency shutdown valves during partial stroke testing, 4- 20mA, 4-20mA + HART,
PROFIBUS PA or FOUNDATION FIELDBUS position transmitters are available in K4-20 variants. K Controls

Enter 211 Earth monitoring system for FIBCs and containers The Earth-Rite FIBC fulfils this need
through intrinsically safe monitoring elec- tronics which continuously verify the con- tainers’ resistance and satisfactory con- nection to earth. When these conditions are confirmed, the system provides local indication to operating personnel in the form of pulsing green multi-LEDS, along with a pair of control contacts (DPDT) which can be interlocked with the process to prevent transfer of product until a safe condition exists. The system is certified for safe use in
Newson Gale has recently upgraded its Earth-Rite FIBC to help ensure that cor- rectly specified static dissipative (SD) or conductive materials are used in haz- ardous area applications involving FIBCS (big bags or super sacks) and other flexible or semi-rigid containers. Type C FIBCs are commonly used to
control the risk of uncontrolled static discharge when loading or unloading bulk powdered and other loose solid materials in hazardous areas. Depending on the application, the

potentially explosive atmosphere where the transfer process takes place may be a combustible dust, or sometimes a dangerous hybrid atmosphere compris- ing dust and solvent vapours. Bearing in mind the inherent risks, it is always necessary to earth the FIBC prior to product transfer. However, in view of the need to attach a mechanical earthing clamp to a flexible tab, many safety conscious organisations prefer to use a monitoring system to take the guess- work out of this operation.
hazardous areas to all major worldwide approvals and can be installed in accor- dance with IECEX/ATEX Zoning or North American NEC Class/Division require- ments. The Earth-Rite FIBC is supplied with a stainless steel earthing clamp assembly, purpose designed for clamp- ing onto flexible/fabric static dissipative materials. The main controller and indi- cation unit is housed inside an IP66/NEMA 4X enclosure and is avail- able with universal AC (110/120 - 220/240V) or DC (12 - 24V) power sup- ply options. The Earth-Rite FIBC forms part of Newson Gale’s range of static earthing and bonding equipment. Newson Gale

Passive UHF RFID tags
The iTAG500 is a range of intrin- sically safe, rugged, passive UHF RFID tags that have recently been released by Extronics and have been designed for use in hazardous process areas such as the oil and gas and petrochemi- cal industries.
From improving asset utilisa- tion and management, to safety, compliance and supply chain operations, the iTAG500 range can provide an RFID solution that can easily integrate into processes and systems.
Developed using Omni-ID technology, the range is intrinsi- cally safe, ATEX and IECEx certi- fied, works both on/off metal and near liquids, has read ranges and accuracy up to 35 metres. Extronics

Shutting down operations to replace faulty lighting can lead to huge time losses and cost implications within hazardous indus- trial plants. However, A new range of high powered LED lights have been launched by NeoBulb to provide a solution. Offering more than seven years of 24 hour continuous usage, the new Escort ATEX range will reduce manufacturing down-time and resultant operational losses. Designed specifically for industries that have to deal with explosives, extreme tem- peratures and ignitable particles, the NeoBulb Escort ATEX range provides ener- gy intensive industries with a simple mechanism for achieving challenging energy reduction targets.
“From factories using dangerous explo- sives, to pharmaceutical facilities with harmful materials, to bakeries with flour filled air, the NeoBulb Escort ATEX range has considerable potential in a range of industries,” explained Simon Leggett, managing director of OCG Lighting, which has exclusive distributor rights for the range in the UK.
The high power LEDs are ATEX compli- ant, meaning they are suitable for environ- ments with flammable vapours, ignitable dusts, corrosive, wet, dusty, and extremely hot or cold conditions. OCG Lighting
