Two-channel relative vibration monitor MMS 6110 is designed for contactless measurement of relative radial vibration of shafts using eddy current sensors epro PR 6422.. PR 6426 with CON converters… The monitor can work as a purely two-channel, where each channel independently evaluates the vibration amplitude in the direction of the sensor orientation.


The second option is the processing of signals from two sensors into one characteristic output variable in several possible ways: API 670: Spp max VDI 2059: S max DIN 45670 A: S max HMmax S k (t) DIN 45670 B: Spp max This monitor is designed, together with other MMS 6000 modules, for the construction of measuring and diagnostic systems of rotary machines, meeting the requirements of the relevant standards. Individual monitors can be part of distributed systems in the local network, after which they provide not only standard values but also pre-processed input data for vibrodiagnostik. The systems designed in this way, in addition to their basic protective function, contribute to increasing the operational reliability and service life of the equipment.

The MMS 6110 2-channel relative vibration monitor enables monitoring of relative vibrations of rotating parts of small and large turbines, compressors, gearboxes, fans, etc. using eddy current sensors. The sensor output signal (monitor input signal) represents the size of the air gap between the sensor face and the measured object. This signal contains a static component corresponding to the middle position of the rotor relative to the sensor, on which a dynamic component representing the dynamic movements of the rotor (vibration) is superimposed. MMS 6110 processes these components separately according to the specified configuration into standard output signals. Additional monitor circuits are used to guard the exceeding of the specified signal limits, supply the monitor and sensors and guard the fault-free status of the entire chain.


The core of the monitor is a microcomputer that allows configuration of various functional modes, parameters of sensors used, measuring ranges and all other necessary parameters. The monitor configuration as well as the reading of the measured data during the monitor revival and servicing is carried out either by a local PC with MMS 6000 configuration program via RS 232 (standard method) or remotely via LAN (if available). If the monitor has information about the machine speed (a phase mark signal is supplied), it also performs a harmonic order analysis and stores in the internal RAM the progress of the last start or run in the form of a Bode graph (vibration as a function of speed) and the progress of the speed change over time. These data and graphs can be viewed, for example, by the specified configuration program or other epro resources.
