Transcription

1 VIBRATION COMPARATOR VC-2200 / 3200 Series VC-2200 VC-3200 There is a wide range of situations in which vibration-based judgments must be made, such as product quality judgment, machinery operation monitoring, facilities diagnosis, and damaged cutting tool detection. ONO SOKKI caters to all your needs with respect to vibration detection, measurement, and judgment.

2 The VC-2200 and VC-3200 Vibration Comparators are high-performance digital signal processors that offer three basic functions: detection, measurement, and judgment. The comparators accept signals from accelerometers to detect abnormalities in machines (detection), monitor vibration levels (measurement), and judge vibration levels based on measurements (judgment). In contrast with conventional measurement devices such as vibrometers, the VC-2200 and VC-3200 can simultaneously process two frequency bands and thus quantify sensory inspection results, which has been difficult previously. Not only for continuous monitoring applications, the comparators can also be used as vibrometers. VC-2200 Condition memory and data memory function Memory function (VC-3200 only) VC-3200 Extracting necessary information from entire vibration data Frequency band setting function (Band variable processing function) Look and judge Digital display function Judgment based on quantitative values Judgment function (comparator output) Listen and judge Abnormal sound will alert you Headphone output Able to perform further analysis Analog output Detects necessary information in a timely manner Comparator gate input There is a time-delay feature Comparator delay time setting Ideal for automation and multiple production inspections RS-232C interface Easy to install into a control panel Compact 96 x 96 (DIN) size

4 Information About Vibration Measurement Why bands? The frequency band in which vibration occurs depends on the nature of the phenomenon that causes the vibration.the VC-2200/3200 use digital filtering to set the frequency band in which particular types of vibration might occur, thereby enabling independent monitoring and diagnosis for each phenomenon. Frequency distribution of abnormal vibration from rotating machinery Low-frequency range Mid-frequency range High-frequency range The relationship between vibration parameter and mode Vibration and sense faculties The relationship between band, parameter and mode often used in equipment diagnosis Visual detection Tactile detection Auditory detection Band Low frequency Frequency range Several to 100 Hz Parameter Displacement* Mode Example of the abnormal cause PEAK Imbalance (total Misalignment amplitude) Rattle Note Related to the amount of displacement or magnitudes of movement Vibration level Displacement Velocity Acceleration Middle frequency Dozens of Hz to several khz Velocity* RMS Wear of bearing Related to the amount of vibration energy or fatigue Displacement Velocity Acceleration High frequency 1to 10 khz Acceleration PEAK Flaws of bearing (half Flaws of gear amplitude) Related to impact forces due to flaws or defects Type of abnormal sound Measured object What is the peak/maximum rms value factor (peak/maximum rms value)? Bearing 1 Good product A In order to judge the degree of bearing's flaw, the peak/maximum rms value factor is effective. It is calculated with a peak value/maximum rms value. A vibration value also varies by the sizes of bearing in a peak value or rms value. The peak/maximum rms value factor has the feature which is not influenced by the size of bearing but can measure the degree of a flaw. Bearing 2 Defective product Contamination by foreign matter Defect A' A A' Shock waves due to flaws or foreign matter Level Peak value Time rms
