Transducers are widely used as they are a must in measuring all physical phenomena in nature. Typically, they convert physical units that we try to measure into a voltage or a current that could be easily processed and displayed. Ideally we want the transducer to a) not upset the quantity being measured. This is a theoretical impossibility as per the principles of quantum mechanics. We can only try to minimize this “loading” effect. We also want the transducers to b) have a one to one correspondence to the quantity being measured. This means that the transducers must not have hysteresis. To be useful the conversion must have c) a wide range, typically a decade or more. Finally it is desirable to have a linear relationship between the quantity being converted and the quantity it is converted to. Other miscellaneous properties, such as noise, stability, cost, response time etc are also to be taken into consideration. [ABSTRACT FROM PUBLISHER] |
