Lenz Law of Electromagnetic Induction says that-The current induced in a loop flows in such a way so as to create a magnetic field opposite to the direction of the field that caused it. It is an another application of Newtonâs Third Law. Regards, Moid
They work on the energy conversion principle. They produce an electrical signal proportional to the input (physical quantity). For example, a thermocouple is an active transducer. Passive Transducers. Transducers which require an external power source for their operation is called as a passive transducer. They produce an output signal in the form of some variation in resistance, capacitance or any other electrical parameter, which than has to be converted to an equivalent current or voltage signal.
Home/Articles/How low pressure transducers work. A pressure transducer is a measuring device which converts an applied pressure into an electrical signal. Generally, a pressure transducer consists of two parts, an elastic material which deforms under the application of pressure and an electrical part which detects this deformation.
