Data


For a temperature variation of 30 ° C, a thermocouple generates an increase of 1.25 mV.

What is the sensitivity?

A pressure sensor offers a sensitivity of 2mV / V / kPa. Considering a 20V supply, what

will the sensor output sensitivity?

A pressure sensor with a measurement range of 0 to 10kPa provides an output signal of 0 to 250mV.

Determine the sensitivity of this sensor.

A strain gauge has a linearity characteristic of 0.5% full scale for a measurement

from 0 to 50 Kg. For a measurement of 20Kg, what are the value of the maximum absolute error, and the value

relative error?

A standard gauge of practically zero uncertainty gives 80 KPa as a pressure measurement than a

another pressure gauge indicates 80.2 KPa. Calculate the absolute error and the relative error on the measurement of the last pressure gauge.

We consider that the measurement of the temperature of a fluid using a thermometer is a system of the 1st

order. Following a sudden increase in the temperature of the fluid by 10 ° C, the thermometer displays an increase of 6.3 ° C after 30 seconds;

1. determine on the percentage graph the sudden increase in temperature of 10 ° C and the temperature 6.3 ° C.

2. determine the time constant  of the system.

3. after how long will the thermometer display 10 ° C?

4. for a sudden increase of 20 ° C what will be the temperature displayed by the thermometer

after a time t = 2?
