Turbine thrust bearing active and inactive temperature is the blade in the turbine trust bearing is actual temperature change, which mitigates the active or inactive bearing.

What is an example of active transducer?

Thermocouple is one example. Photo voltaic cell


Examples of closed loop control system?

A SYSTEM is any active device if left as open loop it will saturate one way or the other if the gain is ample. To control a system it must have some feedback to determine ts linear operating capabilities. As an example an airplane taking off at las Vegas the cabin will be pressurised to -1000 feet from the ground and maintain a rate of climb to even 50.000 feet with a delta of 17 PSI The cabin pressure as a system will maintain this delta by close loop control otherwise we will need oxygen if flying.

What is thermo plastics?

Thermosetting plastics (thermosets) are polymer materials that irreversibly cure, to a stronger form. The cure may be done through heat (generally above 200 degrees Celsius), through a chemical reaction (two-part epoxy, for example), or irradiation such as electron beam processing.Thermoset materials are usually liquid or malleable prior to curing and designed to be molded into their final form, or used as adhesives.The curing process transforms the resin into a plastic or rubber by a cross-linking process. Energy and/or catalysts are added that cause the molecular chains to react at chemically active sites (unsaturated or epoxy sites, for example), linking into a rigid, 3-D structure. The cross-linkingprocess forms a molecule with a larger molecular weight, resulting in a material with a highermelting point. During the reaction, when the molecular weight has increased to a point so that the melting point is higher than the surrounding ambient temperature, the material forms into a solid material.Uncontrolled reheating of the material results in reaching the decomposition temperature before the melting point is obtained. Therefore, a thermoset material cannot be melted and re-shaped after it is cured. This implies that thermosets cannot be recycled, except as filler material.[1]Thermoset materials are generally stronger than thermoplastic materials due to this 3-D network of bonds, and are also better suited to high-temperature applications up to the decomposition temperature of the material.


Conventional heating systems include?

Solar Energy: Active- Using solar panels to warm house . Passive- Using windows ( or no machine.) Forced Air- When air is forced through air vents through out home. Electric- this method uses conduction to warm air around.


What is the difference between a passive transducer and an active transducer?

Passive transducers - require an external power to operate, and theoutput is a measure of some variation in passive components (e.g. resistance orcapacitance)Examples of passive transducer :-Slide-wire resistor▫ Resistance strain gauge▫ Differential transformerActive Transducers - Self generating type - do not require an external power,and produce an analog voltage or current when stimulated by some physical form of energy.▫ Thermocouple▫ Photovoltaic cell▫ Moving coil generator
