  Compatible with Bently Nevada 3300 and 3500 proximity probes, accelerometers, and temperature sensors—supports up to 16–24 channels per enclosure depending on configuration.
• Comprehensive Labeling & Documentation
  Includes terminal identification labels and wiring diagram holders, enabling clear channel mapping and reducing commissioning errors during startup and maintenance.
• Durable Steel Construction
  Heavy-duty powder-coated steel housing withstands mechanical impact, chemical exposure, and temperature extremes (-40°C to +70°C), extending service life in demanding industrial settings.
• Flexible Mounting Options
  Wall-mount design with multiple knockout entries for conduit or cable gland installation, adaptable to field cabinet integration or standalone deployment near machinery.

Typical Application Scenarios

This terminal board case is widely deployed in industries requiring continuous vibration and condition monitoring with high reliability and environmental resilience:

Frequently Asked Questions (FAQ)

Q: How does the Bently Nevada 36853-01 terminal board case integrate with existing 3300/3500 monitoring systems?
A: The enclosure provides organized terminal blocks for field sensor cables, which then connect via shielded extension cables to 3300 proximity probes or 3500 monitor rack inputs. Verify cable length limits (typically 5–10 meters) and grounding requirements per Bently Nevada installation manuals.

Q: What is the maximum number of sensors one enclosure can accommodate?
A: Depending on sensor type and terminal block configuration, one 36853-01 case typically supports 16–24 channels. For larger systems, multiple enclosures can be daisy-chained or mounted adjacently.

Q: Is this enclosure suitable for hazardous area installations (ATEX/IECEx)?
A: The standard 36853-01 is NEMA 4/IP65 rated for general industrial use. For hazardous locations, consult Bently Nevada for certified explosion-proof or intrinsically safe enclosure options.

Q: Can I use this terminal board case for non-Bently Nevada sensors?
A: Yes, the enclosure is compatible with most industrial vibration sensors using standard terminal connections (e.g., 4–20mA accelerometers, proximity probes). Verify terminal block specifications and grounding practices.

Q: What installation environment requirements must be met?
A: Mount in a location with ambient temperature -40°C to +70°C, away from direct water spray (IP65 protects against jets, not submersion). Ensure adequate ventilation if internal heat dissipation is a concern, and follow NEC/IEC wiring codes for conduit entry.

Q: Does the enclosure support remote monitoring or data acquisition integration?
A: The 36853-01 is a passive wiring enclosure. Remote monitoring is achieved through connected Bently Nevada 3500 rack monitors with Ethernet/Modbus communication modules, or via DCS/SCADA integration at the monitor level.
