Introducing an explosion-protection WirelessHART gateway series, R. STAHL now provides even more versatile solutions for over-the-air communication in the process industry. The new product complements the existing line-up to give users a complete package of interface options for signal transmission via 4...20 mA with line-based HART or FF H1 fieldbus. Wireless communication is an easy way to lay the groundwork for sophisticated automation concepts that are deployed to upgrade an extensive base of existing field devices e.g. in the chemical, pharmaceutical, or oil and gas industry. Advanced Industrial Internet implementations all but depend on such solutions. A series 7145 gateway connects up to 100 wireless field devices via Ethernet with the DCS or asset management system. The gateway is easy to install and can be comfortably parameterised via web server.
A robust stainless steel enclosure provides mechanical resistance and protection according to IP65. ATEX and IECEx certified for use in zones 2 and 22, the devices withstand temperatures in a range between -20 °C and +60 °C. Thanks to the flexible housing concept, the gateway can be combined with other components and optionally equipped with an intrinsically safe antenna interface (Ex ia) as well an Ethernet interface with Ex op type of protection. Drawing on a wealth of expertise and engineering experience, R. STAHL offers to assist plant designers and system integrators to devise their custom network. For instance, special solutions for use in zone 1 and 21 can also be supplied if needed. Other customised components such as splice boxes for fibre-optic cables, media converters or terminals for Ethernet copper cables can be integrated as well.
