What is the difference between a passive transducer and an active transducer?
Wiki User
∙ 14y ago
Passive transducers - require an external power to operate, and the
output is a measure of some variation in passive components (e.g. resistance or
capacitance)
Examples of passive transducer :
-Slide-wire resistor
▫ Resistance strain gauge
▫ Differential transformer
Active 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

What is an example of active transducer?
Thermocouple is one example. Photo voltaic cell
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 turbine thrust bearing active and inactive temperature?
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 the role of a tamper switch on butterfly valve?
A tamper switch (in a burglar alarm system for example) is designed to stop un-authorised access to the inside of the control panel. It usually takes the form of a small micro-switch that activated when the cover is opened. Even if the alarm has been de-activated (by entering the correct code) the anti-tamper circuit is still active so long as there is power to the system. Cutting the lead to the external sounder, or the mains lead doesn't stop it either - there is usually an internal sounder, and a back-up battery.
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.
Is a thermocouple an active or passive transducer-why?
is a thermocouple an active or passive transducer?-why?
Is thermocouple a transducer?
Yes, it's an active transducer. A thermocouple is passive not active
What are active and passive transducers?
An example of a passive transducer is differential transformers. The reason why is because passive transducers require an external power supply to operate.
What is the difference between active attacks passive attacks in network?
What is the difference between active attacks passive attacks in GSM network?
The difference between active transport and passive transport is?
Active transport requires energy; passive transport does not.
The difference between a passive and an active dividend policy.?
The difference between a passive and an active dividend policy lies in the amount of time between dividend disbursement. In a passive dividend policy, dividends are given when the company decides it is time. With an active dividend policy, dividends are disbursed at regular intervals.
What is the defference between active transpors and passive transport?
The difference between active and passive transport, is that, active transport, requires energy input from the cell, in order to occur, unlike passive, which occurs, without any energy input.

Difference between active and passive optical component?
Fiber optic couplers can be either active or passive devices. The difference between active and passive couplers is that a passive coupler redistributes the optical signal without optical-to-electrical conversion. Active couplers are electronic devices that split or combine the signal electrically and use fiber optic detectors and sources for input and output.
What is difference between active voice and passive voice?
active is lilly milks the cow . you put the ersons name first. passive is the cow is milked by lilly
What is the main difference between active trasport and passive transport?
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
What id the difference between active and passive transport?
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.
