The first step, in the case of explosive atmospheres, is to consult possible restrictions on the product datasheet.
Then, the device should be positioned on the machine or equipment to be monitored.
The vibration and temperature measurements should be taken on rigid parts of the machine, so that signal and temperature measurements are not impaired. Avoid installation on fins and parts of the fuselage as they may have localized resonance, signal attenuation and heat dissipation. The device must also be positioned on a non-rotating part of the machine.
Since the DynaLoggers take readings on three orthogonal axes, they can be installed in any angular direction. However, it is recommended that one of the axes (X,Y,Z) be aligned with the machine shaft.
The images above show the orientation of the DynaLogger axes. This can also be seen on the label attached to the devices. The correct positioning of the device should take into account the axis and orientation of the machine. The image below shows a DynaLogger positioned on an electric motor.
X=Axial; Y=Horizontal; Z=Radial
To determine the quantity of devices to be installed on a machine, some factors should be taken into consideration:
• Complexity of the equipment: complex equipment with a higher number of components, such as bearings and shafts, may require a greater number of measurement points.
• Criticality of the machine: the more critical the equipment is for production, the closer it should be monitored.
• Reliability of the machine: if a machine is historically unreliable, additional monitoring points could be desirable.
