11/2025 • We reserve the right to make technical changes. Technical data and functions • 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 Measuring -axis Explanation of terms • RMS: Root mean square value • Peak-to-peak: Full vertical length of the sine curve • Integrator: Electrical circuit that integrates an input signal over time • Vibration amplitude: Maximum distance that a vibrating object reaches from its center position • Frequency band: Defined range of frequencies between the lower and upper limit frequencies • Break acceleration: Load limit of the sensor, specified in g (acceleration due to gravity) • Coupling surface: Surface to which the sensor is attached • Roughness: Unevenness of the surface height • Smooth running: Trouble-free running of a machine • DIN ISO 2954: Standard „Mechanical vibration of reciprocating machines and of machines with rotating components - Requirements for vibration severity meters“ • ISO 10816 and ISO 20816: IEC standards for mechanical vibrations • VDI 3832: VDI guideline for structure-borne noise measurements for assessing the condition of rolling bearings in machines and systems
