Hauber 677 type Vibration Sensor

Bearing status parameter for roller bearing diagnostic in accordance with DIN ISO 13373-3The vibration monitoring units HE055 and HE250 also offer the option forroller bearing diagnostics in accordance with DIN ISO 13373-3, in addition tomonitoring the vibration speed in accordance with DIN ISO 10816.In this standardised procedure, proven in practice, the ratio of the effectiveacceleration value (m/s² [rms]) to the peak acceleration value (m/s² [peak])is observed in a range from 10 Hz to 10 kHz.This is called "crest factor” and, based on the norm, is divided into four ranges that represent the bearing status parameter.highest peak acceleration value (in m/s², peak) 300 200Alarm100Warning notice50Normal state30 20very low value10 5 3Effective acceleration value (total value of 10 Hz to 10 kHz in m/s², rms)12351020 30 50 100This simple, meaningful method offers advantages over other, more complexmethods of determining the roller bearing status.Evaluation of this method does not require any other analysis instruments(such as tachometers) or software. Because our sensors provide bearing status monitoring as an additional measurement parameter, no other sensors are required to measure the vibration speed, for example. A dual sensorsaves you the need for all the peripherals that come with attaching a secondsensor.The lower cost and the ease of evaluation that makes this method comprehensible to anyone are also pivotal criteria.11
