Hopping onto the digital transformation train requires that instrumentation supply digital data to host systems. Though capable of providing this information, many HART devices cannot because of their physical connection to analog I/O channels.
One easy way to resolve this issue is through the use of a WirelessHART adapter. Adapters attach to HART-enabled instruments and wirelessly transmit HART digital data to the host. They can be battery powered, or pull power from the existing 4-20mA loop. Several FieldComm Group member companies offer WirelessHART adapters and a recent article in Process-Worldwide featured Pepperl+Fuchs Bullet product.
