List of top Sensors and Industrial Instrumentation Questions

A piezoresistive pressure sensor has a sensitivity of 1 (mV/V)/kPa. The sensor is excited with a dc supply of 10 V and the output is read using a 3 ½ digit 200 mV full-scale digital multimeter. The resolution of the measurement set-up, in pascal is \(\underline{\hspace{2cm}}\).
Given: Density of mercury is 13,600 kg/m\(^3\) and acceleration due to gravity is 9.81 m/s\(^2\). Atmospheric pressure is 101 kPa. In a mercury U-tube manometer, the difference between the heights of the liquid in the U-tube is 1 cm. The differential pressure being measured in pascal is \(\underline{\hspace{2cm}}\) (rounded off to the nearest integer).
A strain gage having nominal resistance of 1000 \( \Omega \) has a gage factor of 2.5. If the strain applied to the gage is 100 \( \mu \)m/m, its resistance in ohm will change to \(\underline{\hspace{2cm}}\) (rounded off to two decimal places).
Input-output characteristic of a temperature sensor is exponential for a
