EPRO A6140 MMS 6140 Monitor
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.
At the MMS 6140 monitor the relative
shaft vibration is measured with an eddy
current sensor and the absolute bearing
vibration with a seismic or piezo-electric
sensor.
The phase shift between the signals,
caused by the different measuring principles, is compensated by the electronics. In the following, the bearing vibration signal is subtracted from the shaft
vibration signal. The time signal arising
thereof is then processed like a normal
vibration signal, converted to a characteristically value according to the configuration parameters, output as current
signal and supervised on limit exceedings (see fig. right)
● Part of the MMS 6000 Machine Monitoring System
● For connection of one eddy
current sensor and one
seismic or piezo-electric
transducer.
● Signal frequency ranges
1...250 resp. 5....2000 Hz
● Both channels may also be
used in single-channelmode, channel 1 for shaft vibration and channel 2 for
bearing vibration.
● Measuring results of both
channels to be combined
with each other for calculation of the absolute shaft vibration.
● Sensor supply balanced to
ground to suppress disturbances in industrial environments
● RS 232 interface for configuration and reading out of
measuring results
● RS 485 interface for connection to epro's MMS 6800
analysis and diagnosis system or to host computers
