BENTLY NEVADA 9200-09-01-01-00 Two-Wire Velocity Seismoprobe Transducer

Description

The BENTLY NEVADA 9200-09-01-01-00 Two-Wire Velocity Seismoprobe Transducer is part of the Bently Nevada 9200 series, a two-wire moving-coil velocity sensor engineered to measure absolute vibration (relative to free space) of bearing housings, casings, or industrial structures. It outputs a voltage signal directly proportional to vibration velocity, enabling accurate vibration monitoring for industrial equipment health assessment. Key technical specifications include a sensitivity of 20 mV/mm/s (500 mV/in/s), with ±5% accuracy when properly terminated and oriented at the calibration angle, and transverse sensitivity limited to 10% or less of axial sensitivity. Its frequency response ranges from 4.5, 10, or 15 Hz up to 1 kHz (60,000 cpm), with typical performance of +0, -3dB. Built for rugged industrial use, it withstands mechanical shocks up to 50 g peak along non-sensitive transverse axes, and operates reliably in temperatures from -29 degrees Celsius to 121 degrees Celsius (-20 F to 250 F). A core feature is its no external power requirement, making it ideal for portable measurement applications, while its moving-coil technology offers reduced sensitivity to impact or impulsive excitation compared to integrating accelerometers. It supports both continuous monitoring and periodic measurements with diagnostic instruments, and can be ordered with an optional corrosion-resistant integral cable for enhanced durability in harsh environments.
