MMS3110/020-020 Dual Channel Shaft Vibration Transmitter

The Dual Channel Shaft Vibration Transmitter MMS 3110 is part of the
MMS 3000 Transmitter System for monitoring and protecting any kind
of turbo machinery. It permits economic measurement and supervision of relative shaft vibrations, measured with eddy current sensors.
Application fields of the system are all types of turbo machinery, fans,
compressors, gear boxes, pumps, and similar machines.
MMS 3000 Transmitters are suitable for great systems with programmable controls and host computers in power stations, refineries and chemical plants, as well as in
smaller plants with few measuring points and decentralized data processing.
The inputs of MMS 3000 transmitters may be used for connecting all epro standard – eddy current sensors PR 6422/.., PR 6423/.., PR 6424/.. and PR 6425/..
The transmitter is not designed for applications in hazardous areas.

MMS3125/022-020

The MMS 3110 Dual Channel Shaft Vibration Transmitter converts the input signals of eddy current
sensors to two independent output signals proportional to the shaft vibration or to one output signal
proportional to the maximum value of both channels according to API 670:
max. (Sppx, Sppy) or – according to VDI 2059: Smax µm.
The integrated module and sensor supervision detects fault functions of both – sensor and module. In this
case the status of the “ok output” (Channel Clear) changes and the
4…20 mA current output switches to 0 mA.
All settings are made with jumpers and DIP switches.
The transmitters are delivered with a configuration suitable for most
applications – if desired any other configuration can be prepared in the factory.
