Technical Features

Measurement of vibrations on bearings or housings for machine monitoring.
The vibration is measured in the axial direction of the sensor in a defined frequency band.
Different types for three measured variables:
– Vibration acceleration (without integrator), particularly suitable for higher-frequency vibrations, e.g. on roller
bearings or gears and for shocks.
– Vibration velocity (integrator), particularly suitable for machine condition monitoring according to ISO 20816.
– Vibration displacement (double integrator), particularly suitable for measuring the vibration amplitude on vibrating conveyors, vibrating screens and sifters.
Suitable for use in harsh environmental conditions.
Record vibrations as close as possible to their source. Flat coupling surfaces with low roughness are suitable. Rough cast surfaces or painted surfaces are unsuitable.
Sensors comply with the specifications for vibration severity measuring devices according to ISO 2954, among others.
Possible fields of application are:
– Measurement of running smoothness on rotating machines and reciprocating machines in accordance with ISO 10816 / ISO 20816
– Measurement of bearing vibrations according to VDI 3832
-Measurement of vibrations in defined frequency bands
