Distributed vibration monitoring saves money by
reducing installation and wiring costs in the following
ways:
smaller footprint reduces cabinet space and enclosure
•
size
"on-skid" mounting and internal Proximitor modules
•
eliminate field wiring and reduce the number of
housings
a network cable may be the only wiring necessary
•
between a central control room and the machine
machine OEMs and packagers who use modular
•
manufacturing techniques can reduce cost by
completely installing, wiring, and testing the vibration
system
break down consists of disconnecting the network cable
•
and power thereby leaving the vibration system intact
and eliminating expensive field wiring and
troubleshooting
the 1701/06 Isolator Terminal Base (ITB) uses internal
•
galvanically isolated safety barriers which eliminate the
need for external safety barriers and an Intrinsically Safe
Earth connection.
FieldMonitor systems are nodes on a field bus network. Each
node consists of an Allen-Bradley or third-party Flex
network adapter, a number of Flex modules depending on
the application, and the Bently Nevada FieldMonitor system.
The Flex network adaptors support a continually expanding
variety of networks. Some examples are:
ControlNet
•
Remote I/O
•
DeviceNet™ adapters
•
Profibus™ DP
•
Modbus® adapters
•
Interbus S
•
Ethernet TCP/IP
•
Appendix F lists the Flex network adapters that Bently
Nevada has tested with the FieldMonitor system.
