MachineGuard Ethernet

The MachineGuard Ethernet based system is capable of measuring multiple various and different measurements especially vibration, whether that be velocity (mm/s), acceleration (“g”) or peak-to-peak acceleration (“g”). Each channel is configured to measure the best signal for the application. The system can measure acceleration on bearings & motors, whilst measuring velocity on gear drives & fans, for example. The system will monitor and trend the overall level of vibration, be that velocity or acceleration. The system can be installed with AC or 4-20mA signal accelerometers, depending on various system requirements.

When AC accelerometers are used, each channel can have a signal conditioner installed c/w a BNC bulkhead mounted socket & terminal D. This enables any individual to connect a hand held vibration analyser to interrogate the FFT signal from each accelerometer and undertake a full diagnostic inspection from a safe location.

This system enables us to have an early warning whilst enabling us to undertake full in depth vibration analysis, analysing:-

  • Acceleration spectra
  • Velocity spectra
  • Displacement spectra
  • Raw waveform

The data can then be transmitted via Ethernet / fibre optic cables, and the protocol used is generally Modbus / TCP/ Ethernet which enables the information to be published into most SCADA type systems and our own stand alone software.

Most systems comprise of the following components:

  1. Stainless steel IP67 enclosure (sizes to be confirmed)
  2. “MachineGuard II” ARM Cortex processor
  3. Power supply units
  4. HMI 7” Touch screens
  5. Signal conditioners input modules, buffered output c/w BNC bulkhead mounted socket & terminal D (Acceleration monitoring)
  6. Glands, cable marking & metal detectable (blue) cable ties
  7. Drawings & O & M manuals



The system has a HMI touch screen which displays locally the ongoing live results of both the velocity, envelope acceleration, temperature or oil quality. The envelope acceleration is ideal for identifying bearing deterioration and failure mechanisms, whereas, velocity is ideal for monitoring mechanical issues such as imbalance, mechanical looseness, misalignment, etc.


The information identified on the screen above is then displayed in greater detail on the software loaded on the networked PC’s. example below of the system:


From here the client is able to view their historical trends along with important data that will enable them to advise on the mechanical impact on OEE.
