The pressure sensor below measures a pressure between 3 to 15 pst and has an output current of 4 to \( 20 \mathrm{~mA} \). The attached circuit converts the current flow to a voltage across a 250 ohm resistor that is then connected to the PLC analog input. Assume the input and output ranges are linear and proportional. Determine the PLC integer register value given an input sensor pressure of \( 12.5 \) PSI. Answer as an integer value between 0 to \( 10000,+1-5 \% \)
Pressure In ? \( 0 / P \) current is \( 4 \mathrm{~mA} \) when pressure is less than 3 PSI. Your Answer:
