I understand the basic principle behind pressure sensor calibration but i am still not able to do a calibration problem. Could someone Explain how you would go about calibrating a standard 4-20mA Differential Pressure Transmitter (DPT) to measure differential pressure in the range 5 to 20 psi?
Or direct me to literature that may be helpful in solving this problem. Thanks in Advance.

A calibrated pressure pump is often used. With the calibrated pressure pump, you would "teach" the instrument that 5 psid is 4 mA and 20 psid is 20 mA.

if you are using a smart transmitter you can use a hart communicator ..set URV and LRV according to your requirement..

pls refer the following link for more information..
