BACKGROUND OF THE INVENTION:
Electrical assemblies include motors, transformers, and the like equipment.
A motor comprises a rotor and stator. It may be coupled with a heat exchanger for cooling the motor continuously, thereby preventing it from damage. The rotor is the rotating assembly of the motor. The stator is the stationary part of the motor.
There are many solutions applied to cooling assemblies which regulate its functions when the cooling assemblies are adjunct with motors, transformers, or other such electrical assemblies. However, there is always a display mechanism which depicts the status of heat and other sensed parameters in the electrical assemblies, its cooling mechanisms, and the like.
According to the prior art, analogue type temperature gauges were used. These are dial type gauges. These do not include any visual or aural alarm means. Also, their placement is such that it is difficult to see them without illumination, especially from a distance.
It is necessary, that these be visible in a large factory, especially under crucial conditions such that a worker may be instantly aware of the status of temperature and take further action.

Also, there is no action that takes place during conditions when bearing temperature increases.
PRIOR ART:
CN101704341 discloses a speedometer; hence resistance is added with the settings and it depends on revolution of gears. CN101704341 discloses only one moving indicator for speed measurements. The moving indicator of CN101704341 does not have any radium point contact for easy visualization.
GB568934 relates to mounting and operation of the dial type thermometers and does not provide any technical linkage with the type of settings and visualizations.
GB1453709 also refers to a speedometer and depends on speed of the vehicle.
