Question

An iron cored transducer is excited with a frequency of $15kHz.$ The maximum value of frequency of displacement to be measured with this transducer should not exceed ____ $kHz.$

• A. 1.5

Answer 1

The correct option is A 1.5
$\because \text{For iron cored trnasducer supply frequency}$

$f_e\ge 10\times \text{[frequency of displacement}\left(f_m\right)]$

$f_m\le \frac{f_e}{10}$

$f_m\le \frac{15}{10}$

$f_m\le 1.5kHz.$
