Bently Nevada 3500/25 149369-01 Vibration Monitoring Module

BENTLY 3500/25 149369-01 module, as a professional vibration monitoring and keyphase signal module, is widely used in industrial machinery condition monitoring systems. The following is a detailed introduction to this module.

Basic information

Model: BENTLY 3500/25 149369-01

Type: Keyphase module

Function: Used to provide key signal to the monitoring module on the 3500 rack, receive input signals from eddy current sensors or electromagnetic sensors, and convert this signal into a digital key phase signal. This signal can indicate when the key phase mark on the shaft passes through the key phase probe.

Technical specifications

Number of channels: 2 channels

Size: Half height module

Input signal range:

Non insulated I/O modules: -0.8V to -21.0V

Insulated I/O module:+5V to -11V

Power consumption: 3.2 watts under normal conditions

Automatic threshold value: The minimum signal amplitude triggered is 2V peak to peak, and the minimum frequency is 120rpm (2Hz)

Manual threshold value: used for any input greater than 0.017Hz (1rpm for 1 event per revolution), triggering a minimum signal amplitude of 500mV peak to peak

Hysteresis: 0.2 to 2.5V, user selectable

Features and advantages

Enhanced design: This module is an improved version of the 3500 system, which maintains full downward compatibility with existing Keyphasor modules in terms of appearance, assembly, and functionality, and can be used in traditional systems.

High compatibility: It can be directly inserted into the framework to replace old keyphasor modules (such as PWA 125792-01), facilitating system upgrades and replacements.

Multifunctionality: Supports TMR (Triple Module Redundancy) configuration. When system key input is required, the 3500 system should use two key modules that work in parallel to provide main and auxiliary key signals.

Accurate measurement: The key phase signal provides precise time measurement, allowing the 3500 monitor module and external fault diagnosis equipment to measure vector parameters such as 1X amplitude and phase.

Application scenarios

The BENTLY 3500/25 149369-01 module is widely used in various situations that require precise monitoring of the status of rotating machinery, such as power plants, petrochemicals, steel metallurgy, aerospace and other fields. In these fields, this module can effectively monitor the vibration and speed of rotating machinery, prevent mechanical failures, and ensure production safety.

Suppliers and Prices

Due to market prices changing over time, promotional activities, and other factors, specific real-time prices cannot be provided. However, according to the general market situation, the price of this module usually ranges from thousands to tens of thousands of yuan. It is recommended to directly contact the supplier or manufacturer for the most accurate price information when making a purchase.

In summary, the BENTLY 3500/25 149369-01 module is a powerful and stable vibration monitoring and keyphase signal module that plays an important role in industrial machinery condition monitoring systems.
