Description
The Bently Nevada Low Frequency Velocity Sensor is designed to measure absolute (relative to free space) bearing housing, casing, or structural vibration. The two-wire system consists of a transducer and appropriate cable.
The Low Frequency Velocity Sensor is ideal for capturing vibration data in installations where vibration frequencies of less than 4 Hz provide valuable data. Its main use is to measure bearing casing vibrations on hydroelectric turbines where slow rotating speeds require a low signal to noise ratio. The 330505 Transducer is a two-wire design that uses moving-coil technology with embedded signal conditioning circuitry to provide a voltage output directly proportional to the transducer's vibration velocity. The 330505 Transducer connects to an interconnect cable and is then directly attached into the 3500/46M Hydro Monitor. This transducer currently does NOT interface with the Trendmaster* family of products. Additionally, due to capacitance constraints, hazardous area approvals will NOT be available on this product.
