BENTLY NEVADA 3500-40M

1. Core Overview & Functions

• Product Positioning: It is the Frame Interface Module of the BENTLY 3500 Machinery Protection System.
• Main Purpose: Monitor key parameters of rotating machinery such as axial displacement (thrust), differential expansion, eccentricity, and REBAM® (vibration amplitude) to realize predictive maintenance and fault prevention of machinery.
• System Composition: It is usually used with modules such as 3500/41R (proximity sensor) and 3500/32 (relay module) to form a complete monitoring system.

2. Key Technical Parameters

• Number of Channels: 4 channels, supporting simultaneous monitoring of multiple devices or multiple parameters.
• Operating Voltage: 24 V DC (typical value), supporting a range of 18 - 32 V.
• Power Consumption: Maximum 15 W, typical value about 7.7 W.
• Environmental Adaptability:

  Dimension Specifications: Approximately 35 mm × 225 mm × 200 mm, suitable for 19-inch rack or DIN rail mounting.

  • Operating Temperature: -40°C to +85°C.
  • Protection Level: IP65 (dustproof and waterproof).
• Certification Standards: Equipped with CE, UL, SIL 2 (functional safety) and other certifications; some models can be optional with ATEX Zone 2 (explosion-proof).

3. Main Product Features

• High-Precision Monitoring: Adopting advanced signal processing technology, it can provide high-precision mechanical parameter data to help users quickly identify potential faults.
• Flexible Communication Capability: Built-in 2 10/100M Ethernet (RJ45) interfaces and RS-485 (Modbus) interface, supporting multiple industrial communication protocols such as Modbus TCP/IP, OPC DA/UA, DeviceNet, and Ethernet/IP.
• Modular Design: Compact size (standard module size) and light weight (about 1.5kg), facilitating quick installation and maintenance.
• Easy Integration: It can be configured graphically through BENTLY 3500 Configuration Software, and supports non-volatile memory for storing alarm history and event logs.

4. Typical Application Fields

This module is widely used in various high-risk and high-value industrial scenarios:

• Energy Industry: Steam turbines, gas turbines, steam turbine unit bearing boxes, and generator sets in thermal power plants.
• Oil & Gas Industry: Various types of centrifugal compressors, reciprocating compressors, and oil pumps.
• Heavy Industry: Rolling mills in steel plants, paper machines in paper mills, looms in textile mills, etc.

5. Installation & Maintenance Guidelines

• Installation Method: Supports 19-inch rack mounting (DIN rail) and wall-mounted mounting. The appropriate installation depth should be selected according to the on-site cabinet specifications (such as standard rack depth 349mm or wall-mounted depth 267mm).
• Power Supply Requirements: It is recommended to use the original power supply, providing main power and redundant power to ensure that the system can switch automatically when the main power fails, ensuring the continuity of monitoring.
• Maintenance Recommendations:
  • Regularly check the chassis tightness and heat dissipation to ensure the operating temperature is within the normal range.
  • Regularly calibrate the proximity sensor (such as 3500/41R) to ensure the accuracy of displacement measurement.
  • Check the system log through BENTLY 3500 Configuration Software, clear expired alarm records, and ensure that the software version matches the hardware firmware.
