The absolute vibration can be measured in frequency ranges of 10… 1000Hz and 4… 1000Hz, with vibration amplitudes of up to 2mm and 3mm (peak to peak), respectively. It can provide an electrical signal proportional to the vibration velocity. Suitable for various types of turbomachinery, fans, compressors, gearboxes, pumps, coal mills, and other machines.

Functional Principles and Design
Measurement element: composed of seismic mass blocks with coils, suspended on diaphragm springs, moving in the circular gap of permanent magnets, and guided by diaphragm springs in the longitudinal direction (measurement direction) of the measurement element.
Working mode: The sensor operates above the resonance frequency (different models have resonance frequencies between 4 and 13 Hz), while the seismic mass remains stationary. Due to the vibration of the sensor housing, an electrical signal proportional to the vibration velocity is generated.
Damping: The damping of the measuring element is achieved through a damping cylinder or external device, with a damping value of about 0.6 and good linear characteristics throughout the entire frequency range.
Special design: Measurements below the resonance frequency can be corrected by corresponding amplitude response; When the vibration amplitude is too high, the mechanical limiter will reduce the maximum amplitude of the seismic system; Each sensor is designed for a measurement direction (vertical or horizontal). The PR 9266/.. Series sensor has an additional lifting coil, which adjusts the center position of the seismic element by inputting a lifting current of up to 7mA into the coil; The PR 9268/.. Series sensors can directly input the boost current into the measurement coil, but this current must be separated from the measurement signal. The measurement amplifier of MMS 6000 supports the operation of absolute bearing vibration sensors and provides boost current.
