ATEX and IECEx Flame-Proof Versions Now Added To Pressure Sensor Platform
With the introduction of two new flame-proof versions, the UNIK 5000 pressure sensing platform from the Sensing business of GE Measurement & Control (USA) can now offer accurate, reliable and high integrity solutions for an even wider range of pressure sensing applications. The new UNIK 5800 and UNIK 5900 sensors will allow customers greater choice when faced with the rigorous requirements of operations in hazardous zones. They provide a lightweight and cost-effective alternative to pressure gauges and switches, especially in the oil and gas and process sectors.
“Our UNIK 5000 platform already carries intrinsic safety and FM and FMc certifications,” explains Sean Coyle, product manager at GE, “The introduction of our new flame-proof versions means that we can now offer an extended range of options for hazardous zone applications to meet individual customer requirements, in pressures from 3.5 bar to 700 bar."
The new products have been engineered to allow them to be certified for ATEX and IECEx flame-proof approval. These certifications require that the construction of the product is sufficient to contain any explosion or flame within the product to prevent any spread which might cause a major explosion. As a result, flame proof certification does not require the installation of barriers or safe area power supplies, although there is a requirement to install suitable pressure-resistant equipment,
such as cable conduits. The choice of hazardous area equipment depends very much on the application and flame proof products can often offer the most cost-effective solution.
The UNIK 5800 and UNIK 5900 are in-line male and female conduit versions respectively and the UNIK 5900 is available in long or short body designs. Each combines silicon technology and analogue circuitry with modular design and lean manufacturing techniques to offer custom-built pressure sensors from standard components, matching accuracy and specification to meet individual requirements. This modular design feature has already contributed greatly to the success of the UNIK 5000 platform, allowing short delivery times for a high quality, robust sensing solution.

Level Measurement up to +450 °C with New Guided Wave Radar
Refractory ceramic and stainless steel combined with the latest level measurement technology – that’s the new VEGAFLEX 86. Developed by Vega (Germany) for extreme industrial applications, this GWR sensor measures liquids safely and reliably up to an operating temperature of +450 °C and a process pressure of 400 bar.
VEGAFLEX 86 is ideal for level and interface measurement of liquids. It delivers accurate and reliable results even in extreme temperatures from -196 to +450 °C and process pressures from -1 to +400 bar – in steam boilers as well as in bypass tubes or standpipes. Thanks to its ability to measure products with a minimum dielectric constant of 1.4 and higher, its application range is virtually unlimited.
The versions with cable, rod or coaxial probe and standard process connections such as threads from G1½ A (1½ NPT) and flanges from DN 50 (2") allow installation on any container or tank. The electronics versions are 4 ... 20 mA/HART, Modbus, Profibus PA and Foundation Fieldbus – to ensure simple connection to any process control system. In addition, the single and double chamber housings of plastic, aluminum and stainless steel make it possible to create an instrument version suitable for any process environment.
Setup wizards and new, intelligent signal processing functions also facilitate setup and commissioning and ensure stable, accurate readings. Since it was developed according to IEC 61508, the sensor meets the requirements of SIL2 and SIL3, when deployed in homogenous redundancy. A welded, gas-tight feed through (Second Line of Defence) brings additional safety to facilities handling hazardous materials. Last but not least, the standard approvals for explosion protection in gas and dust, for example ATEX and FM, round out the selection options.

Affordable Camera Packs for R&D Applications
FLIR Systems (France), a leading technological innovator in thermal imaging, has introduced the affordable SC35, SC15 and SC5 camera packs for R&D applications.
Thermal imaging cameras can be used for a wide variety of R&D applications. However until now access to high performance thermal imaging cameras was often the privilege of just larger R&D groups. Visualising temperatures from -40°C to +550°C,with temperature differences as small as 50mK, the new ultra-compact SC Series Camera Packs bring the advantages of research grade thermal image to the test bench of every R&D engineer.
In the R&D environment - the thermal imaging camera is just one part of the solution, of equal importance is software to analyse the thermal image. Designed with R&D engineers in mind - FLIR Tools+ software is included with every SC35, SC15 and SC5 Pack. Working seamlessly with SC Series Camera Packs - FLIR Tools+ software enables researchers to view, record and analyse thermal image data with functions such as time versus temperature plots. For experiments that require more than one camera to cover the object, or for stereoscopic applications, it is also possible to configure one SC Series Camera to be master and others to be slave(s).
The FLIR SC Series Camera Packs come standard with GigE Vision - a state-of-the-art camera interface developed using the Gigabit Ethernet communication protocol. GenIcam is also supported on the FLIR SC Series Camera Packs to provide a generic programming interface for all types of cameras. Therefore regardless of interface technology (GigE Vision,Camera Link, 1394 DCAM, etc.) or features implemented, the Application Programming Interface (API) will always be the same.
