The points to be considered in determining a transducer suitability for a specified measurement are as follows:
1.Range. The range of the transducer should be large enough to encompass all the expected magnitudes of the measurand.
2.Sensitivity.The transducer should give a sufficient output signal per unit of measured input in order to yield meaningful data.
3.Electrical output Characteristics.The electrical characteristics-the output impedance output signal should be compatible with the recording device and the rest of the measuring system equipment.
4.Physical Environment. The transducer selected should be able to withstand the environmental condition to which it is likely to be subjected while carrying out measurements and tests.such parameters are temperature,acceleration,shock and vibration,moisture,and corrosive chemicals that might damage some transducers but not others.
5.Errors.The errors inherent in the operation of the transducer itself,or those errors caused by environmental conditions of the measurement,should be small enough or controlled enough that they allow meaningful data to be taken.
