OPAMP: LM124J The purpose of which is to level shift the response from the Pressure transducer above zero. http://pdf1.alldatasheet.com/datasheet-pdf/view/27206/TI/LM124J.html
Pressure Transducer: Outputs a frequency response for a change in pressure. Frequency is in the 36-38kHz range.
Voltage Regulator has a resistor in front of the positive terminal because the voltage regulator was getting too hot. This seemed to correct the issue.
Resistor values in the op amp circuit are all the same R=1000 ohms
Resistor prior to voltage regulator R=75 ohms
Capacitor = 100nF
