Description
1. Product Title
Bently Nevada 16925-66 – 3-Conductor Shielded Accelerometer Interconnect Cable (66 Feet)
2. Product Overview
The 16925-66 is a factory-terminated dedicated signal cable designed for Bently Nevada piezoelectric accelerometer vibration monitoring systems, mainly serving as the transmission link between 330400 / 330425 series casing vibration accelerometers and 3500 rack monitoring modules. It adopts a three-conductor fully shielded twisted structure, with one end fitted with a locking 3-socket aviation plug for direct docking with the accelerometer, and the other end pre-crimped with open terminal lugs for convenient wiring to terminal blocks or signal input boards inside control cabinets. The multi-layer braided shielding of 16925-66 effectively blocks EMI/RFI interference generated by high-frequency inverters, high-voltage switchgear and large rotating motors, minimizes high-frequency vibration signal attenuation and waveform distortion over long-distance 66-foot (20.12m) routing. The high-temperature, oil-resistant outer jacket withstands harsh industrial field conditions, ensures complete and accurate transmission of bearing vibration, gear meshing and casing acceleration signals, and provides reliable data support for equipment predictive maintenance and safety trip protection logic.
