The One Series Ex d includes cULus, ATEX and IECEx approvals for Class I, Division 1 (Zone 1) areas. These triple agency approvals provide an instrument that is ready and certified by third-party testing for use in hazardous locations in many parts of the world, including N. America, Australia and Europe. The Russian approval Gosgortechnadzor will be added to the product at a later date, to be announced.
The current economic conditions and delays with projects are providing opportunities for the One Series as a cost-effective alternative to transmitters used for trip point/on-off service. Assuming 20-25% of transmitters used for a project are allocated to trip points, the cost savings to move to the One Series can help reduce the project instrumentation costs, and help satisfy clients who are looking to save money and keep the projects moving forward.
Throughout industry, new and existing plants are required to design standardized instrument safety into their control schemes. With superior self-diagnostics and faster response than a transmitter, the One Series makes an ideal safety switch and has been evaluated by Exida, LLC. Customers now have the ability to incorporate the One Series into their Safety Instrumented System designs using the data provided in the FMEDA and SIL Verification reports prepared by Exida.
The installed base of mechanical switches is a natural target for the One Series Ex d. We estimate that approximately 4 million switches have been installed in the past 25 years, and are now due for replacement. Instrumentation upgrades provide an excellent opportunity for the One Series Ex d.
