I an in search of a pressure transmitter in which I can set the input range (resolution) via serial port using LabView. Possibly sending a string to the transmitter to tell it what range so as to get the best resolution as possible. The application is that I need to measure pressures that can range from say 1 to 2 psig upto 400-500 psig. I would like to be able to set the range of the transmitter to say 0-10,0-100 or 0-500 based on an initial pressure reading. Any recomendations would be appreciated. Thanks Dan Caragher
Assuming that you are looking for a pressure transducer (I'm not familiar with "transmitter" name), I'll suggest PX971 from Omega. It's a piece of equipment and it seems to be exactly what you are looking for.
You can find a short description here [http://www.omega.com/ppt/pptsc.asp?ref=PX971&Nav=prew01] or complete specs [http://www.omega.com/Pressure/pdf/PX971.pdf]. Anyway, take a look to their entire presure related product line.
