This new solution dispenses with the need for special antennas certified for explosion protection. Such special-purpose antennas are usually costly, only available in a limited range of types, and often depend on fixed cables without plug connectors that are difficult to modify. Instead, any standard antenna can be used and connected to the HFisolator via conventional coaxial connectors. Such antennas can therefore very easily be repositioned, serviced, or replaced. The HFisolator tolerates extremely rough climatic conditions with ambient temperatures ranging from 60 °C to +80 °C. Using the ISM frequency bands around 900 MHz, 2.4 GHz, and 5 GHz, the HFisolator supports all wireless transmission standards commonly applied in industrial environments (WiFi 802.11 a/b/g/n; WirelessHART; ISA 100.11a; Bluetooth; ZigBee; EnOcean).
In addition to type 9730 HFisolators, R. STAHL provides a wide range of Ex d and Ex p enclosures for radio systems. The explosion protection specialist is a trusted partner for wireless solutions in hazardous areas with many years of experience working in this field.
