Hello everyone. I've started a project is which I plan to measure a differential pressure between 0-1 psid, amplify it, and feed it into the ADC pin of a micro-controller. The differential pressure sensor I'll be using must be a wet/wet type capable of handling either liquid or highly humid gas on either side. After looking around a bit, the sensors that seem to be the cheapest while still meeting the requirements are made by Honeywell. The 24PC01SMT and the 26PC01SMT both look like they would work well with the only difference between the two being that the 26 is temperature compensated and calibrated and the 24 is not.
Temperature compensation for my project would be ideal because the sensor may experience temperatures anywhere between 32F - 100F. Unfortunately, the temperature compensated model is significantly more expensive than the other one ($26 as opposed to $13).
So here's my question. If I used the non temperature compensated sensor, could I build temperature compensation into the circuit instead of having it built into the sensor? How would I go about doing this? Would this be difficult? More or less expensive? Also, if anyone knows of a different sensor that might fit my needs, please let me know. Thanks in advance for any help.
