MMS 6125

The MMS 6125 Dual Channel Bearing Vibration Monitor processes signals ofpiezoelectric vibration sensors in accordance with VDI 2056 or corresponding international standards. Depending on the used sensor type the following measuring ranges and modes can be selected:

MMS 6140

The MMS 6140 dual-channel monitor has been designed for the use with two different transducers. Channel 1 operates with eddy current sensors and channel 2 with seismic or piezoelectric sensors.
Each measuring channel can operate separately or the results of both channels may be used to calculate the difference. By means of calculating the difference of these signals, the absolute shaft vibration results
