pressure sensor amplification

Other Parts Discussed in Thread: INA122, INA333

am using sm5652 sensors for measuring low pressures. Can i use ina122 along with this for the amplifications for sm5652?. i need to connect the amplifier output to the arduino.

Inayath,

The SM5652 is a voltage driven pressure transducer and should work fine with the INA122. However, assuming you excite the SM5652 with a 5V supply it will be necessary to connect the (REF pin 5) input to a mid-rail (say 2.5V) source so that the INA122 can swing positive and negative if your pressure input swings positive and negative.

I have successfully used the later INA333 instrumentation amplifier with the SM5652.

regards,

Richard

THANK YOU ...

DOES I NEED TO ADD EXTRAS TO RECTIFY THE ERRORS?, OR IT WILL WORK PERFECT THE INA122?
