Penny + Giles introduces two can bus interface versions of its popular contactless rotary position sensor
New pre-torque holders facilitate
difficult rupture disc installations
P
ressure-management specialist Elfab (
www.elfab.com) has introduced a range of pre- torque holders for its metal rupture discs. The new range has been specifically designed to cope with installations where it is difficult to remove the disc and holder separately from the flange, and to reduce both the risk of the disc slipping or of either component becoming damaged. The pre-torque holders are supplied in either forward- or reverse- acting formats, and have been designed to be compatible with Elfab’s unique magnetic burst detection system, Flo-Tel™+, in keeping with the rest of the company’s holder range. Available in stainless steel as standard, the new holders offer a high level of corrosion resistance. They have been produced to comply with all internationally recognised flange standards. The pre-torque holders will allow even more rupture disc users to benefit from Elfab's technically advanced designs and detection.

The SRH520CN provides either J1939 or CANopen options according to ISO/DIS 11898 and features a 14 bit Hall effect sensor offering 0.022° resolution. The J1939 version is factory programmed to offer Direction, Baud Rate, Node ID and Frame Rate parameters. The CANopen version offers Baud Rate or Node ID parameters, but is customer configurable to the CIA standard DS 301 protocol and supports the device profile for DS 406 encoders. Both models have shaft-side protection to IP69K; a minimum IP67 to the rear when the M12 connector is attached and fully engaged; and operate from a 9–30Vdc unregulated supply. OEMs can also specify the output in a clockwise or anticlockwise direction. The SRH520CN is offered in a marine-grade aluminium housing and is designed to meet the harsh operating requirements of heavy duty industrial position sensing applications.

Quick-Fit steam trapping station saves energy and cuts carbon emissions
isolation valves, steam trap connector with strainer and a check valve in a sleek modular body, supported by a 10-year warranty for total peace of mind. A steam trap can be replaced in minutes instead of hours, enabling steam systems to be kept at peak performance and energy efficiency. Plant downtime is also reduced significantly. Traditionally, steam traps are welded or screwed into the pipeline and considerable work is needed to replace them. Often this means that an underperforming steam trap needing maintenance is left in place for a significant period until safe access can be arranged. The single-piece body of the STS17.2 also virtually eliminates the potential leak paths caused by screwed connections that conventional steam trapping stations and on-site fabricated installations typically suffer.

he Dupont™ Kalrez® Spectrum™ 6380 is a non-black sealing product, that has been specifically developed for chemical processing applications involving hot and aggressive amines. Amine plants are operated throughout the world, typically in oil refineries and gas plants for the removal of H2S (hydrogen sulphide) from a product stream such as natural gas. New sources of oil and natural gas fields in the Middle East can incorporate up to 30% of H2S which is known as ‘sour gas’. However, the new, stricter environmental standards require ever decreasing contents of H2S, and the process of removing this contaminant from natural gas is commonly referred to as sweetening.
H2S is highly toxic and needs to be handled with care as it can cause embrittlement in metal equipment. Together with the harsh chemical environments and high temperatures that
amine processes operate under, destructive swelling can occur with conventional elastomeric sealing components including fluoroelastomers (FKM) and perfluoroelastomers (FFKM). Loss of mechanical properties and extrusion of O-ring seals can result, leading to leakage and increased valve operating torques where seal face deformation has also occurred. These problems have led to the development of the Kalrez® Spectrum™ 6380 range by Dupont™, designed to provide extended seal performance and operating life for applications in chemical and hydrocarbon processes involving hot, aggressive amines, strong acids and oxidising media. The extension to MTBR (Mean Time Between Repairs) of valves and pump mechanical seals, together with process leakage reduction helps to reduce maintenance costs while also lowering emissions. Typically the tripling of seal service life to one full year of trouble-free operation has been achieved for current users.
Identified by their cream colour, these products are suitable for both static and dynamic sealing, and together with other specialised sealing products in the Kalrez® Spectrum™ range, are all available in the UK from Dichtomatik Ltd, an authorised Dupont™ distributor.
In test results the Kalrez® Spectrum™ 6380 perfluoroelastomer products exhibit outstanding resistance to amines and strong oxidisers, exhibiting 10 – 15 times lower swell compared to FKM and four times lower swell over general purpose FFKM sealing items. The products are also suitable for continuous use at temperatures up to 225°C, with occasional excursions at even higher temperatures for short durations. They can be supplied in standard AS568 and metric sizes, with custom O-ring sizes and other shapes also available.

Ocean Optics Offers R&D Funding with Blue Ocean Grants
Ocean Grants program (
www.blueoceangrants.com). The program seeks innovative and novel proposals that solve challenging problems and improve the world using optical sensing. Applicants from all disciplines are encouraged to apply before the September 1, 2012 deadline.
O The program is
designed to facilitate open innovation and spur the development of new optical sensing technologies with potential for market commercialization. The international program is open to applicants from academia and industry around the world. 2011 winners had a diverse range of ideas with extremely high quality proposals ranging from novel spectrometer and spectral imaging architectures to emerging applications as diverse as low cost surface enhanced Raman spectroscopy, early prostate cancer detection techniques,
and new nano-liter
microfluidic chip architectures. The Blue Ocean grants are divided into two phases. Phase I grants are issued to fund initial evaluation and development of ideas and technologies to the proof of concept phase. Phase II grants will be issued to nurture a proposed technology through proof of concept in a way that enables the potential of market commercialization.
