Better lubricants and bearings are reducing friction and microprocessors monitor engine conditions and make adjustments to keep operation at peak efficiency without actions by the driver. 

Suppose we find that in a test of an automobile engine to monitor the combustion of 1.00 L of octane under various conditions, only 1.14 kg of carbon dioxide is produced, not the 2.17 kg of the theoretical yield. Then...

Fig. 6 illustrates a list of recommended inspection items. Not all the items listed will be appropriate for all plants, and some additional items might need to be added to meet special needs. Also, some of the items listed are not routine, such as the evaluation of used filters and failed parts hence, the work will need to be appropriately divided among operators, lubricant technicians, condition-monitoring technicians, and plant engineering.

Spectroraetric oil analysis has been applied for more than 40 years as a routine and cost-effective condition monitoring technique [1]. It is used to determine the elemental concentration in parts per million of wear metals, contaminants, and additives in a used oil sample. Commercial oil analysis laboratories report on as many as 20 different elements. With the knowledge of the wear metal and contaminant limits for the machine or engine being monitored, a determination may be made as to whether or not that equipment is operating properly.

Implementation Routes and timing are established, people are trained, and the program is implemented. Readings are taken, analyses are performed, and recommendations for action are provided to maintenance, engineering, and operations. A strict condition-monitoring discipline will lead a plant to a successful predictive maintenance environment where people at all levels of a plant will be able to visualize the resultant equipment saves. ...

It s used in thallium-mercury alloys for applications in switches that are used at sub-zero temperatures, and it can be used in laboratories as a low temperature thermometer because it extends the freezing point of Hg to -60 C. This can be used by engineers to monitor conditions at such low temperatures. 

Military convoys with smart tags (RFIDs with independent power sources) have been used to facilitate information gathering in the field as deployment changes and conditions unfold. Continuous monitoring of engine conditions or blades in aircraft enable proactive maintenance, thus enabling quick aircraft turnaround.

Plant engineers shall carry out condition monitoring of all key equipments. Preventive maintenance schedules shall be drawn and implemented. Sufficient inventory of critical spares shall always be available to avoid development of dangerous situations due to continuous running of equipments without repairs.

Condition Monitoring and Preventive Maintenance The temperatures, pressures, flow rates, pH, current drawn by drive motors for the process units and machineiy in the plant should be regularly checked. The observed values should be always compared with instmctions from plant manager. These should be, however, within maximum limits given by manufacturer. In case of any doubt senior engineers should be immediately consulted.
