3500/06 Weatherproof Housing
Datasheet

Bently Nevada Machinery Condition Monitoring141528 Rev. HDescription
The Bently Nevada 3500/06 Weatherproof Housing protects
the 3500 System against adverse environmental conditions,such as excessive moisture, dirt, grime, and unclean air. An
optional purging system protects the rack from outsideelements.
The housing is specially designed for system installations that
require environmental protection or where safety standards
mandate air purging to meet approval agency requirements.
The weatherproof housing is available in either epoxy-coatedsteel or 304 stainless steel and is compatible with a full-size
rack (rack mount), mini-rack (rack mount), and internalbarrier I/O modules.
When using the weatherproof housing, you should takeprecautions to avoid operating the monitors above theirtemperature specifications. Due to the heat dissipated by the3500 monitoring system, you should not use theweatherproof housing in direct sunlight.
Exceeding the specified operating temperature of
the 3500 system may degrade the reliability of themonitoring system and potentially ignite somegases.

All wiring is routed through conduits mounted to the Weatherproof Housings. Both upper
conduits are for transducer power, signal input, and recorder output wiring. Both lower
conduits are for power input and relay wiring which should not be mixed in the same conduit
with transducer, signal, and recorder wiring.
The Static Purge Pressure (Pressure required to insure that a Hazardous atmosphere does not enter thehousing), must exceed 50.8 mm (2.0 in) of water. This is measured on the gauge (after the housing
has been purged), with the valve in the closed position.
All test and recommendations made by Bently Nevada are in accordance with specifications andrequirements made by National Fire Prevention Agency in pamphlet 496 for Type "Y" purge, orCanadian Electrical Code: C 221.1, Part 1. For additional information on purge requirements refer toabove standards.
