Self-powered, wireless field instruments

23 September 2016

Schneider Electric has introduced the new Foxboro Accutech line of wireless field instrumentation, including a range of self-powered measurement and control devices that communicate wirelessly with a centralised gateway. 

The Accutech line is said to offer cost-effective monitoring of processes in remote locations– specifically in applications where wiring is prohibitive, power is not available, and the environment is demanding. 

Within the local instrument networks, Accutech field devices are able to transmit signals up to 1,000m, and can connect, configure, and communicate quickly using a 900 MHz or 2.4 GHz license-free spectrum. For instrument networks spanning larger areas, the instruments can be equipped with extended-reach Trio data radios that support 256-bit AES-data encryption. 

A single Accutech base radio can report data from a local network of up to 100 field instruments and up to 256 base radios can coexist for maximum scalability.

The range line includes devices for level, flow, pressure, temperature, and control applications. Each field instrument incorporates Foxboro technology and is built for durability and long-term operation in hostile environments, with NEMA4X packaging and CSA Class 1, Div 1, and ATEX/IECEx (-ai and –d) certifications. All of the field units are equipped with field-replaceable batteries that offer up to 10 years of service.
