Information

Overview Manuals Common Applications Product Precautions
The 16925-02 is a 2-foot long, 3-wire shielded interconnect cable designed to connect Bently Nevada accelerometers (such as the 330400 or 330425). One end features a standard 3-socket MIL-spec connector, while the other end is used for connection to monitoring system terminal blocks.
    • High-performance shielding suppresses EMI/RFI
    • Features a rugged MIL-C-5015 compliant connector
    • Fully aligns with API 670 standards for machinery protection
This passage details the core performance and application positioning of the Bently Nevada 330400 and 330425 accelerometers. These sensors are specifically engineered for harsh industrial environments, targeting critical machinery applications where casing acceleration measurements are essential, The 330400 strictly adheres to the API 670 standard, offering a 50 g peak amplitude range and a high sensitivity of 100 mV/g, making it the preferred choice for most machinery protection systems. In contrast, the 330425 maintains an identical design but is optimized for higher-impact scenarios, increasing its amplitude range to 75 g peak while adjusting sensitivity to 25 mV/g to capture more intense mechanical movements. This tiered specification allows users to flexibly select the most suitable front-end sensing element within the 3500 monitoring system based on the actual vibration intensity of their equipment.

Power Generation
Connecting casing accelerometers to monitor bearing housing vibration and gear mesh frequencies.

Oil & Gas
Transmitting high-frequency vibration signals to detect early blade fatigue or aerodynamic surge.

Steel & Metallurgy
Stably transmitting fan casing acceleration signals in environments with strong electromagnetic interference.

Paper & Pulp
Transmitting sensor data in high-temperature environments to monitor gear set meshing quality.

Air Separation
Monitoring bearing vibration of high-speed integral gearboxes.

General Manufacturing
Monitoring acceleration of remote gearboxes to prevent drive chain failure.

 When using the 16925-02 interconnect cable, the focus is on signal integrity and connector protection, ensure the MIL-C-5015 plug is fully tightened for proper sealing, and strictly follow the pin definitions (typically A-Common, B-Power, C-Signal) to prevent sensor damage. Since the cable is non-armored, avoid sharp edges during routing and use protective conduit to prevent mechanical wear or prolonged oil exposure. Additionally, ensure the shield is single-point grounded at the monitoring end (rack end) to effectively suppress EMI, ensuring accurate acquisition of high-frequency vibration data.
