BENTLY NEVADA 9200-01-02-02-00 Two-Wire Velocity Seismoprobe Transducer

Description

BENTLY NEVADA 9200-01-02-02-00 Two-Wire Velocity Seismoprobe Transducer is a two-wire device designed to measure absolute vibration (relative to free space) of bearing housings, casings, or industrial structures. Built with moving coil technology, it produces a voltage output directly proportional to vibration velocity, and offers lower sensitivity to impact or impulsive excitation compared to solid-state velocity sensors, making it suitable for demanding industrial applications.

Key technical specifications include 20 mV/mm/s (500 mV/in/s) sensitivity with ±5% tolerance 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 ±0 to -3 dB accuracy. The transducer has a dynamic response range of 2.54 mm/s (0.1 in/s) peak-to-peak and can withstand mechanical shocks up to 50 g peak along its non-sensitive transverse axis.

Engineered for harsh industrial environments, it operates in temperatures from -29 degrees Celsius to 121 degrees Celsius, features dust and moisture resistance, and can be ordered with an optional corrosion-resistant integral cable. It requires no external power, making it ideal for portable measurement applications, and supports a maximum cable length of 305 meters (1000 feet) without signal attenuation.
