Opti-Gard™ was previously available in either the OPR or OPK design, depending on the burst pressure required. Simple enhancements made to that version have enabled Elfab to produce a single-disc design covering the full range of sizes and burst pressures, offering customers potential stock reductions of more than 65 per cent.

Opti-Gard™ recently became the first ever rupture disc to be covered by a three-year warranty, demonstrating the ongoing reliability of a range initially launched in 2003. Furthermore, the disc is still supplied with Flo-Tel™, Elfab’s non-invasive ATEX-approved burst detection, as standard. With tolerance of three per cent across a wide range of burst pressures and a 95 per cent operating ratio, Opti-Gard™ continues to offer the highest performance characteristics available for liquid, gas or vapour applications.

New Ocean Optics Measurement System for Quality Inspection of Solar Simulators

RaySphere a powerful spectroscopic system for irradiance measurement from 380-1700 nm

Ocean Optics (www.oceanoptics.com) has introduced an optical measurement system for absolute irradiance measurements of solar simulators and other radiant sources. The RaySphere enables measurement of absolute irradiance (mW/cm2/nm) over different spectral ranges from the UV to the NIR (380-1700 nm).

RaySphere is especially useful to solar simulator manufacturers and R&D labs as a tool to validate the output of installed solar flash lamps. The flash of a solar simulator is used within the photovoltaic (PV) manufacturing process for the binning of cells according to spectral response and for final PV module efficiency measurements. RaySphere provides a system with the necessary accuracy and resolution to measure and analyze the performance and stability of the flasher, with advanced, ultra-low jitter triggering electronics for timing the measurement to the flashes. The calibration of the RaySphere has been validated by an accredited certification lab to ensure accurate detection, allowing evaluation and qualification of the spectral distribution of solar flashers and simulators according to norms established by standards-setting bodies such as ASTM and IEC (IEC60904-9 2007).

Two thermo-electrically cooled detectors allow highly repeatable and accurate spectral analysis of solar flashers from 380-1700 nm. A second version of RaySphere contains a single cooled detector for measurement to 1100 nm.

The system also includes advanced, high-speed electronics and an intuitive and powerful software interface. Extremely brief measurement times enable the detection of a complete spectrum during a flash or even during a portion of the flash. In addition, the measurement can be triggered by a fast response photodiode that reacts on the increasing intensity of the flashlight with sub-microsecond response times.

Most similar products are unable to operate above 150W (200µm core) without active water cooling. Fiberguide’s new line is designed to handle more power and survive at higher temperatures with a passive, air-cooled design. An integrated mode stripper dissipates up to 25W of power from the cladding, ensuring a clean output and boosting power handling capacities to 100W (100µm core), 250W (200µm core) or 350W (400µm core), depending on system conditions.

Assemblies have an epoxy free cantilevered nose design, which isolates the optical fibre from the ferrule to prevent thermal and contamination problems. Fibre tips are laser polished for maximum transmission. Cables contain all silica fibre and are available with 100µm, 200µm and 400µm cores for easy integration into existing systems.

Elfab launches Radio-Tel™, the first ATEX-approved wireless burst detection system

Suitable for the largest sites, Radio-Tel™ features real-time process monitoring of disc status and temperature. Situated in close proximity to the rupture disc, Radio-Tel™’s transmitters plug easily into the Flo-Tel™+. This eliminates the time-consuming and expensive wiring work necessary with all other detection systems.

The transmitters send a health message to the receiver every minute. When the transmitter detects that a disc has operated, the message changes to an alert signal.

Elfab has designed Radio-Tel™ to deliver maximum flexibility to its customers.  Each transmitter emits a unique identification code with each health message, providing end-users with control over individual units. The system’s PC-compatible software indicates disc status, enabling customers to easily monitor their processes from the control room. The software allows for detailed monitoring of each device, including exact location, process temperature, battery life and signal strength. Additionally, Radio-Tel™ can be hardwired to deliver maximum control over individual processes, or to trigger a beacon or siren in the case of a burst detection occurring.

Radio-Tel™’s fail-safe receiver module features optimal outputs and is pre-set for both hardwiring and software monitoring. The module can receive signals from a distance of up to 0.5km; for larger sites, harsh operating environments or where buildings and structures weaken signals, repeater aerials are recommended.

Suitable for use in even the harshest of operating conditions, all Radio-Tel™ parts have at least an IP65 rating, with the transmitters being fully ATEX Zone 0 approved.
