I am using a pressure sensor (MPX2053) for my final year project. the output of the sensor is differential. for that i have designed a circuit that takes the difference of both the output of the sensor and gives their difference at the output. the figure below shows the circuit. .... the problem is that the circuit is working fine in simulation but on hardware it is not working.... please help me... circuit is in the link below... i have used 10K resistors

You really need to use an instrumentation amplifier. The circuit you have posted will load the output of the pressure transducer and has unequal loading on the two inputs.

You need to show your circuit and also explain what 'your problem' actually is.
