Can Piezoelectric transducer act up as both actuator and sensor at the same time?

Yes a peizoelectric sensor can act as an acuator as well and at the same time. One the peizoelectric crystall is deformed by a force or apressure it sends an electric signal. And when an electric signal is applied toa peizoelectric sensor it gets deformed & this deformation can be used as the actuation for the controll purpose.

What is ultrasound transducer?
In general, a transducer is a device for changing one form of energy into another. There are lots of things that qualify as transducers under that definition. Just to cite a few examples, a microphone converts the mechanical energy of sound into electrical energy. A speaker does the opposite. An acoustic hydrophone converts the mechanical energy of sound in water or another fluid into electrical energy. In an example of how a transducer works, in ultrasound investigating technology, an electrical signal is used to create mechanical energy in the transducer, thus creating an outgoing pulse. Then the returning mechanical energy, the echo, is converted into electrical energy by the same transducer. The electrical signal is then used in imaging what the transducer is "looking at" by creating a picture of some sort which will then be evaluated. In another way, it could be said that a transducer is a device for sensing and relaying a signal, but keep in mind the idea of a change of "form" of the energy. That's what a transducer does is make the change. A transducer might be used to detect level, pressure, temperature, flow, displacement, accelaration, velocity, etc., from the sensing location so it can be sent to another place (like a control room). It consists of different parts like sensing element (the sensor), signal conditioning unit (filtering, amplification, etc.) and in some cases protocol interface (in order to convert the measured value into a digital frame for example). The latter transducer falls into Smart Transducer category. Links to relevant posts can be found below.
What is the difference between through-hull transducer and transom mount transducer?
A thru-hull transducer is mounting through the hull of the boat. So you would actually take the boat out of the water, drill a hole in the boat approx 2" in diameter(depends on transducer model) and mount the transducer "thru-hull." -- A transom-mount transducer is a transducer bolted to the transom of a boat. Both kinds of transducers need to be submerged in the water for them to work correctly. www.sailboattalk.com I dont know a whole lot about this but I do know you dont drill a hole thru the hull. I have a ranger and from the factory mine was placed inside of the hull under my battery storage no hole needed to be drilled. But on a transom mount you have to drill holes into the transom.
What is difference between photoelectric sensor and proximity sensor?
photoelectric sensor-sense both metal & non-metal proximity sensor -sense metal only
Where is the bank 1 and bank 2 sensor on 1998 Lincoln navigator?
they are both on the exhaust after the cat and are both pretty easy to get to ---------------------------------------------------------------------------------------------------- On a 1998 Lincoln Navigator : Bank 1 is the passenger side of the engine Bank 2 is the drivers side of the engine Sensor 1 on both sides is closest to the engine ( upstream sensors used to help adjust the fuel ratio ) Sensor 2 on both sides is in the exhaust AFTER the catalytic converters ( downstream sensors , also called catalyst monitors )
Why is the traction off light service vehicle light and brake light on always in a 1999 Oldsmobile Intrigue?
Usually caused by a bad ABS sensor or wiring harness to the sensor. Both are serviced with a hub-bearing assembly.
What does an ultrasound scanner consist of?
the transducer and the data processing unit. The transducer both produces the sound waves that penetrate the body and receives the reflected echoes. Transducers are built around piezoelectric ceramic chips.
Is there a difference between a photo transducer a photo sensor and a photo electric transducer if there is one what is it?
No There is not much a difference you can draw between a Sensor & a transducer, as both does the same thing of measuring an energy in form & converting it to other form. But a transducer will make an additional effort to convert the energy into measurable electrical form & then then transmitting!!!! Pls coment
What is the difference between the sensor and the transducer?
In the general case, a sensor is the complete assembly required to detect and communicate a particular event, while a transducer is the element within that assembly which accomplishes only the detection of the event. At the risk of getting too abstract, a transducer converts an input to an output that can be exploited to accomplish the sensing mission. For example, a pressure sensor may use a diaphragm and/or strain gage to "detect" pressure differential across the diaphragm, but he complete sensor will additionally consist of a display element and the electronics required to energize and condition the output of the detecting transducer, as well as the elements required to house and drive the display feature. A compass is a simple sensor of magnetic north, wherein the magnetic element in the compass is the transducer or "north detector" and the needle, housing and compass face comprise the remainder of the "north sensor". In special cases, a sensor and a transducer can be the same. For example, a bi-metallic spring element can both detect temperature change, and may well be the entire sensor if a pointer is attached to the bi-metalic spring.
What is the basic circuit of transducer?
The question here has been framed wrongly. There is nothing like a general circuit for a transducer. Depending on a transducer you may have many circuits. For eg. a Piezoelectric crystal is a transducer, it can convert both ways; mechanical vibrations to electrical and electrical to mechanical. So you see, there is nothing like a general circuit for a transducer. Another better example would include an Antenna which converts electro-magnetic waves into a electric signal. All that you can say at max is that a transducer is a device that converts one form of energy to another. And that is either due to the virtue of the property of a material or due to a certain circuitry which will vary from transducer to transducer.
What is a pressure transducer?
Transducer (i.e. a device for converting energy from one form to another) for both vacuum and positive pressure.
What is a compound pressure transducer?
Transducer (i.e. a device for converting energy from one form to another) for both vacuum and positive pressure.

How are piezoelectric materials that contain silicon used in science and industry?
Piezoelectric materials have been integrated with silicon microelectromechanical systems (MEMS) in both microsensor and microactuator applications. Some recent and emerging applications of piezoelectric MEMS are acoustic emission microsensors, vibration monitors, molecular recognition biosensors, precision positioners, micropumps, and linear stepper motors. - See more at: http://www.chacha.com/question/how-are-piezoelectric-materials-that-contain-silicon-used-in-science-and-industry#sthash.EpLIkFTw.dpuf

Why does my 1994 grand Marquis AC blows cold sometimes then blows supper hot the refrigerant level is good?
2 thing's ambient temperature sensor malfunctioning if you have computer controlled a/c or heater a/c blend control actuator. I've seen both problems.
