⚑Technical Specifications

The absolute vibration transducers of the PR 9268/.. families have been designed to measure absolute vibrations in the frequency ranges 10..1000Hz and 4...1000Hz. with vibration amplitudes of up to 3mm (peak-peak). They provide electric signals proportional to the vibration velocity. The transducer family offers several basic types to cover a wide range of industrial measuring applications. The robust construction and the splashproof housing permit the transducers to be mounted even in hostile environments. Application areas of the transducers are all kind of turbo machinery, fans, compressors, gear boxes, pumps, coal mills and other machines. The transducers PR 9268/60 and PR 9268/70 are suitable particularly at high temperatures - i.e. for applications at gas turbines. Moreover, these transducers include electric adaptations to supersede the MMG 033 and MMG 1033 absolute vibration transducers of the former AEG Kanis group. For this, three different transducer sensitivities are at disposal, depending on the type of measuring amplifier. The high output level and the low impedance of the measuring coil effect a high interference immunity. Subsequent measuring amplifiers of the epro MMS 3000 and MMS 6000 Machine Monitoring systems pick up and process the vibration signal without the need of additional intermediate amplifiers. Machine Monitoring Systems Function principle and design: The measuring element of the absolute bearing vibration sensor PR 9268 consist of a seismic mass with a coil, suspended on membrane springs and moving in the circular gap of a permanent magnet. The membrane springs lead the measuring element in the longitudinal direction (=measuring direction). The sensors are operated above the resonance frequency, which is between 4 and 13 Hz, depending on the type. The seismic mass remains at rest and due to the vibration of the sensor housing, an electric signal proportional to the vibration velocity is generated. epro – transducers are dynamic sensors with the measuring coil as part of the seismic element, moving in the field of the permanent magnet. Damping of the measuring elements is realised by damping cylinders resp. by external wiring and set to a value of approx. 0,6, resulting in a very linear characteristic over the entire frequency range. Measurements below the resonance frequency can be made with corresponding corrections of the amplitude responses. In case of too high vibration amplitudes, mechanical limit stops reduce the maximum amplitude of the seismic systems. Each transducer is designed for one measuring direction (vertical or horizontal). Deviations of these directions will result in rest positions of the seismic mass different to the normal positions which effects a reduction of the maximum vibration amplitude and the generation of additional spurious resonance’s. When using sensors of the PR 9268/.. family, lifting currents may be fed directly into the measuring coil. However, this current must be decoupled from the measuring signal. Measuring amplifiers of the MMS 6000 family are designed to support this operation and to supply lifting currents for absolute bearing vibration sensors
