Overview Manuals Specifications Use Cases Configuration & Programming Firmware & Updates

Features:

  • Dedicated signal link between the 330400/330425 Accelerometer and monitoring system termination
  • Integrates 3-conductor shielded 22 AWG construction with 3-socket plug and terminal lug connectivity
  • Supports vibration monitoring applications across industrial rotating machinery installations
The Bently Nevada 16925-70 operates as the dedicated interconnecting cable for the 330400 and 330425 Accelerometer Acceleration Transducer, providing reliable signal transmission between the accelerometer and the monitoring system interface. It continuously maintains shielded signal integrity across lengths from 2.0 ft (0.6 m) to 99 ft (30 m) and routes the 3-conductor signal path through the 3-socket plug and terminal lugs to support steady-state operation of vibration measurement channels. Seamless signal transmission is standard with the 16925-70, however using proper shield grounding practices at the monitoring system end will allow optimal noise suppression in the event of electromagnetic interference.

The 16925-70 provides essential signal path functions common to the entire vibration monitoring channel, and is a critical component of the measurement path, directly affecting the proper, normal operation of the overall accelerometer-based monitoring system. One 16925-70 cable is required per accelerometer installation depending on the distance between the transducer and the termination interface. The 16925-70 occupies minimal routing space in the installation environment and is always positioned between the accelerometer socket and the system terminal block or junction box.

For multi-channel vibration monitoring applications, the monitoring system requires an additional 16925-70 cable installed for each accelerometer channel. In addition to standard single-channel operation, the multi-point configuration also performs parallel signal routing. The 16925-70 multi-channel setup executes reliable transmission using the shielded 3-conductor construction specified in the cable design.

The 16925-70 Bently Nevada 3-core shielded cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Bently Nevada 16925-70 is a 3-conductor shielded 22 AWG (0.5 mm²) cable specifically engineered for reliable signal transmission in industrial vibration monitoring environments. This 16925-70 cable features a 3-socket plug at one end and terminal lugs at the other end, providing a secure and standardized connection interface for accelerometer installations. The 16925-70 is available in lengths ranging from a minimum of 2.0 ft (0.6 m) to a maximum of 99 ft (30 m), offering flexibility for various installation configurations.

This 16925-70 cable is designed for use with the 330400 and 330425 Accelerometer Acceleration Transducer models. It addresses the critical challenge of maintaining signal integrity in high-electromagnetic-interference industrial environments, where unshielded or poorly shielded cables can introduce noise and data distortion that compromise vibration monitoring accuracy. The 16925-70 effectively resolves these issues by providing robust shielding that protects the 3-conductor signal path from external electrical interference, ensuring clean and reliable data transmission from the accelerometer to the monitoring system.

The 16925-70 finds application across multiple industrial sectors, including power generation, oil and gas, petrochemical processing, pulp and paper, and manufacturing facilities. It is particularly suited for installations requiring precise vibration measurement on rotating machinery such as turbines, compressors, pumps, motors, and generators. The 16925-70 cable supports both permanent monitoring systems and periodic diagnostic setups where the 330400 and 330425 accelerometers are deployed.

For installation and integration, the 16925-70 should be routed away from high-voltage power cables and sources of strong electromagnetic fields to maximize shielding effectiveness. The 3-socket plug connects directly to the accelerometer, while the terminal lugs at the opposite end facilitate secure termination to the monitoring system terminal block or junction box. When integrating the 16925-70, ensure that the shield is properly grounded at the monitoring system end to maintain optimal noise suppression. For upgrades, verify that the existing cable length falls within the 2.0 ft to 99 ft range of the 16925-70, and consider replacing older or damaged cables with the 16925-70 to restore signal quality and system reliability. If longer runs are required, evaluate the use of signal conditioning or proximity probe alternatives to maintain measurement fidelity.

Technical notes
The Bently Nevada 16925-70 serves as a critical communication link for the 330400 and 330425 accelerometers and accelerometer sensors, ensuring seamless and lossless transmission of raw acceleration signals from the sensor head to the monitoring module. The Bently Nevada 16925-70 is primarily used in heavy industry sectors such as power generation, oil and gas, and chemical processing to monitor critical rotating machinery, including gas turbines, steam turbines, and large industrial compressors.
