EPRO MMS3120/022-100 Dual Channel Bearing Vibration Transmitter 
Description:
MMS3120/022-100 dual channel bearing vibration transmitter is part of the revised MMS 3000 transmitter system for monitoring and protecting any kind of turbo machines.
MMS3120/022-100 is without Bus-communication,two isolated and independent current outputs, with display.
The transmitters of the new generation are characterised by their highly flexible hardware options and their versatile combination possibilities and can thus optimally be adapted on the demands of the respective plant.
They permit economic measurement and supervision of absolute bearing vibrations by using seismic absolute vibration sensors.
Application fields of the transmitters are all kind of turbo machines, fans, compressors, gear boxes, pumps and similar, rotational machines.
Due to the bus capability, MMS 3000 transmitters are applicable for big systems with programmable logic controls and host computers as
used in power stations, refineries and chemical plants, as well as for small plants with only few measuring points and decentralized data
processing.
The inputs of the transmitter may be operated with all epro absolute bearing vibration transducers:
PR 9268/20, PR 9268/30,
PR 9268/60 and PR 9268/70
The MMS 3120/.. Dual Channel Bearing Vibration Transmitter converts the signals of vibration transducers into two independent signals
proportional to the vibration velocity or the vibration amplitude (peak – peak) or to an output signal proportional to the maximum of
these characteristical values.
The integrated module and sensor supervision detects fault functions of both - sensor and module electronic. In error situations the status of the "OK" output changes and the 4...20 mA current output indicates 0 mA. 
All required configurations are made by means of the MMS 3910W configuration software. The transmitters are delivered with a standard configuration suitable for most applications, if desired any other configuration can be prepared in the factory.
