Description

MG-4 is ideal for the continuous monitoring of everything which has rotating parts.

It´s an excellent starting point for measuring the state of individual machines but will also serve as the mainstay of a future total online solution. A small and compact monitoring unit, sensors and a few cables are all you need. Simple to maintain, low costs, no investment limits, easy to add to.

MG-4 provides:

Display of measured value with continuous updates.
Analogue output 4 - 20 mA with programmable range in steps of 10 mm/s RMS (VIB) or 10 dB (SPM).
Relays 250 V (1) and 125 V (2 for MG4-1, 4 for the others) with programmable alarm levels.
You can select the power supply (230 Vac, 115 Vac or 15 to 30 Vac/Vdc), the frequency range (lower frequency range 3, 10 or 100 Hz, upper 1000 or 2000 Hz) and the SPM technique (dBm/dBc or LR/HR). MG-4 has a casing for wall mounting (IP65). It can be connected to a PLC or relay the machine status via GSM. Measuring time, alarm levels, alarm delay and the chan-nel/relay combinations are programmed, using the push buttons on the front panel.

MG4-Ref11
A special kind of MG4 is the MG4-Ref11, developed for the pulp and paper industry for continuous monitoring of refiners. This unit has been adapted to the special requirements for extremely fast measurements necessary to detect imminent disc segment failure.
