bently nevada 3500/40M Displacement monitor Measurement point configuration requirements
Key phase: each shafting of the compressor unit with the same speed is equipped with a key phase measurement point; Bentley 3300XL series eddy current sensor was used for measurement.
Shaft vibration: Each sliding support bearing is equipped with a pair of X/Y direction (vertical installation of each other) shaft vibration measurement points, using Bentley 3300XL series eddy current sensor for measurement.
Axial displacement: each thrust bearing of the compressor unit is equipped with a double redundant axial displacement measuring point; Bentley 3300XL series eddy current sensor was used for measurement.
Watt vibration (optional) : Two watt vibration points (mounted horizontally and vertically) are installed on each rolling support bearing, and the Bentley 330500 series Velomitor piezoelectric vibration speed sensor is used for measurement.
Gear box shell vibration (if applicable) : a pair of X/Y direction shell vibration measurement points are provided at the supporting bearings of the input and output shafts of each gear box; Bentley 330400 series piezoelectric vibration acceleration sensor was used for measurement.
