V/bar and a full-scale range of 100 bar. The output voltage of the sensor is 10 V when the pressure applied is 100 bar. Calculate the output voltage of the sensor when the pressure applied is 50 bar.

To calculate the output voltage of the sensor when the pressure applied is 50 bar, we can use the formula:

V_out = V_fullscale * (P/P_fullscale)

Where:
V_out is the output voltage of the sensor
V_fullscale is the output voltage when the pressure applied is at the full-scale range
P is the pressure applied
P_fullscale is the full-scale range of the sensor

Given:
V_fullscale = 10 V
P_fullscale = 100 bar
P = 50 bar

Substituting the given values into the formula, we have:

V_out = 10 V * (50 bar / 100 bar)
= 10 V * 0.5
= 5 V

Therefore, the output voltage of the sensor when the pressure applied is 50 bar is 5 V.
