I have been handed two 0-5v pressure transducers with a 0-15psi range and need to connect them to the MicroLogix 1100 analog inputs (0-10v) for a storage tank level system.
The min pressure I will will see at the transducer will be 0 psi and the max will be 3 psi. I would not have personally chose this transducer and would also have used an analog input card for better resolution but am forced into the current situation.
What I believe I've figured out is that the ML1100 has a 10 bit resolution (0-1023 raw value) and being that it has a 0-10v input, my 0-5v would translate to 0-511 raw value (assuming the transducer is at it's max of 15 psi).
Assuming that I will only ever see 3 psi as my maximum pressure, my raw value would be 511*(3/15)=102 if my calcs are correct. Clearly this is not a very good way to set this up.
Can someone please point me in a better direction. Thanks in Advance.
