MG-4
Machine Guard 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.
The MG-4 family consists of four programmable measuring units for vibration severity (VIB) and bearing condition (SPM). The difference is in the channel combination:
| VIB channels | SPM channels | |
|---|---|---|
| MG4-1 | 1 | 0 |
| MG4-2 | 2 | 0 |
| MG4-12 | 1 | 2 |
| MG4-22 | 2 | 2 |
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.
