Bently Nevada 3500/42M-05-00 Proximitor Seismic Monitor

Core Advantages

• Four-Channel Versatile Monitoring: The module features four independent, isolated analog input channels that can be configured in pairs to perform up to two different measurement functions simultaneously. For example, Channels 1 and 2 can monitor radial vibration while Channels 3 and 4 perform thrust position monitoring.

• Comprehensive Measurement Capabilities: Each channel can be programmed using the 3500 Rack Configuration Software to monitor and report multiple parameters including radial vibration, thrust position, differential expansion, eccentricity, REBAM, acceleration, velocity, shaft absolute, and circular acceptance region.

• Advanced Alarm Logic: The module continuously compares monitored parameters against configured alarm setpoints to drive alerts and danger conditions. Alert setpoints can be configured for each active static value, with danger setpoints for any two of the active static values. Alarm thresholds can be set from 0% to 100% of full scale.

• Enhanced Signal Processing: The "M" designation indicates this is the enhanced version with optimized signal processing algorithms and diagnostic capabilities, meeting API 670 5th edition requirements for mechanical protection systems. The module features high-speed sampling (≥10 kHz) with advanced filtering for reliable data acquisition in electrically noisy environments.

• Comprehensive Self-Diagnostics: Front-panel LED indicators provide local status information including OK (module operating properly), TX/RX (communication with other rack modules), and Bypass (module in bypass mode). The module also supports sensor open/short circuit detection and internal circuit self-checking.

• Hot-Swap Capability: The 3500/42M supports hot-swapping, allowing replacement without interrupting the operation of other modules in the rack.

Frequently Asked Questions

Q: What does the model number 3500/42M-05-00 represent?
A: The model number breaks down as follows: 3500/42M = Proximitor/Seismic Monitor (enhanced version); -05 = CSA, ATEX, and IECEx hazardous area approvals; -00 = No additional options.

Q: What types of transducers can be connected to this module?
A: The 3500/42M accepts input from proximity probes (eddy current), velocity transducers (Velomitor), and acceleration transducers (accelerometers).

Q: Can I use different measurement functions on different channels?
A: Yes, the monitor channels are programmed in pairs and can perform up to two different functions at a time. For example, Channels 1 and 2 can perform radial vibration monitoring while Channels 3 and 4 perform thrust position monitoring.

Q: What is the purpose of the OK, TX/RX, and Bypass LEDs?
A: The OK LED indicates when the module is operating properly. The TX/RX LED indicates when the module is communicating with other modules in the 3500 rack. The Bypass LED indicates when the module is in Bypass Mode (protection functions temporarily disabled).

Q: Does this module support hot-swapping?
A: Yes, the 3500/42M supports hot-swapping, allowing replacement without disrupting rack operation.

Q: What configuration software is required for this module?
A: The module is configured using Bently Nevada's 3500 Rack Configuration Software, which allows independent configuration of each channel including sensor type, sensitivity, alarm thresholds, delay times, and relay logic.

Q: How fast can you ship this module?
A: As this is a stock item, we typically ship within 24 hours of order confirmation via global express services like DHL or FedEx.
