LASER LEVEL TRANSMITTER FOR HARSH ENVIRONMENTS
ABB has expanded its level measurement portfolio with the addition of the LLT100 laser level transmitter. Specifically designed for industrial applications and
harsh environments, the LLT100 enables precise measurement of any solid or liquid surface, including
clear liquids from –40° to +60°C, or up to 280°C with a cooling tube. With its IP67/NEMA 4X
explosion proof Class 1 / Division 1 (Zone 1) enclosure, it can be used in a
range of applications, including mining, aggregates, oil and gas, chemicals, food and beverages, power, pulp and paper, pharmaceuticals, and water and waste water. Offering a resolution of 5mm, an accuracy of ±20mm and an eye-safe, Class 1 laser beam with a divergence of less than 0.35°, the LLT100 can be used in low visibility conditions. Its range spans from 0.5m to 30m for liquids, 0.5m to 100m for solids and 0.5m to 200m for positioning applications with a reflective target. A rotating bracket and a swivel flange option allows
precision aiming of the beam, while a laser pointer tool is used to provide a visual reference when aligning the LLT100. With no maintenance or calibration needed, the LLT100 offers
a low cost of ownership. Featuring ABB’s common four-button HMI, it offers flexible installation and a simple setup function, with the use of a Through-the-Glass (TTG) user interface eliminating the need to remove the transmitter cover. The LLT100’s standard enclosure material is powder- coated aluminium, with 316L stainless steel as an option. This, together with with a choice of a range of flange fittings or Tri-Clover 3-A, makes the LLT100 suitable for food production applications or others where a high standard of hygiene is demanded. Outputs are both analogue, using NAMUR compliant 4mA to 20mA, and digital HART 7. For non-ideal conditions, various accessories and options are
also available. These include a dust tube to prevent dirt or splashing liquids getting on to the lens. A number of services are provided by ABB to help ensure the
continued operation of the LLT100 throughout its life. These include product commissioning, maintenance and field services, repairs, spares parts services and training.

Optical fibre manufacturers can quickly assess the geometry of their product with a new high speed automated measuring system from Arden Photonics. The FGC-G range delivers operator-independent results in less than ten seconds. The measurement capability for end-face
geometries includes core diameter, core non- circularity, cladding diameter, cladding non- circularity and core-to-cladding concentricity. Designed for both specialty and telecoms fibres, the units have the latest software that makes it possible to measure even multicore fibres automatically. Two models are available, with the FGC-GT
optimised for 125um diameter fibres but also able to measure up to 400um. Typical applications are the manufacture of single and multimode telecom fibres, although specialty fibres can also be measured. The FGC-GS is optimised for specialty fibres such

as octagonal and dual-cladding types.
For cladding
diameter and non-circularity measurements the units operate in reflection mode. The use of clear end-face illumination provides precise, automatic focusing so that defects on the fibre circumference can be detected and eliminated from the fit, giving greater measurement accuracy. Transmission mode is used for core diameter and
non-circularity measurements, with illumination provided by an array of nine LEDs, giving fully filled launch over a wide range of fibre types.

Following the award of a $165M contract from the US Department of Defense (DoD) in September 2016, VPI has designed and developed an advanced radiological detection system (RDS) prototype. This advanced RDS consists of a base
unit with plug-in probes for detecting different types of radiation in a wide range of scenarios. The final system will be delivered in January 2018, followed by an 18-month testing period. VPI’s RDS will be in use across all branches of the United States Armed Forces, as well as the US Coast Guard, emergency responders and NATO (especially in Canada and the UK). Such collaboration requires the system to be adaptable to many different applications. VPI is able to provide this flexibility through its experience in the design and development of radiation detection technologies. VPI’s CEO, Morgan Taylor,
commented: “The development of this project highlights VPI’s collection of outstanding skills and capabilities in world-class design, testing and qualification, and manufacturing. Also, it complements our existing radiation detection equipment line. I am especially pleased with the incredible team members we have at VPI, their hard work and dedication to the principles upon which VPI is built and their efforts on this project.”

FLOW CONTROL
CUSTOMISATION AND ASSEMBLY SERVICE
Bürkert offers a wide range of flow control products that can be used to create tailored measurement and control systems. For customers that are not already panel builders or system integrators these products need to be connected together to create process assemblies and mounted onto panels or into cabinets. Hence, Bürkert UK has extended its customisation and assembly service to take care of anything from a single valve manifold to a series production run of fully populated cabinets.
Bürkert supports many clients who
build process control panels. For less conventional applications or where a bespoke design and assembly process is required, and it does not conflict with other customers service offerings, Bürkert can offer the expertise of its in- house engineers to create a solution that will deliver the process requirements of an application. Process control panels and valve
assemblies are required in numerous applications and their function demands accuracy and reliability. Bürkert has access to a vast range of standard products as well as having the capability to manufacture one-off or short run components specifically designed to improve a fluid control system. With Bürkert’s experience in hygienic
applications, this service can be highly beneficial to those operating in the pharmaceutical, food and beverage industries. The company’s knowledge of the hygienic sector and the issues that are faced by those involved in regulated process control environments, enables the manufacturer to offer bespoke solutions to unique problems. Designed to occupy a minimal
footprint, Bürkert’s range of control valves and manifolds can be used to create a bespoke process control systems in a compact arrangement. Bürkert’s products are supported by a number of experienced designers and engineers, offering advice in designing and installing a new control system with a commitment to deliver the best value and long term reliability.
