330505 Low Frequency Velocity Sensor
330505低频速度传感器
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.
Specifications
