Hi, I am wondering how to determine the input voltage for a wheatstone bridge? Is there standard rules for the voltage that is applied? I am assuming I'd like to keep the current low while trying to optimize my output resolution. However, I was hoping to learn about some sort of "gold standard"?
These are the specs from the transducer:
Operating Temperature Range 150 to 400C
Storage Temperature Range 250 to +700C
Sensitivity 5.0~VNImm Hg i 1%
Nonlinearity and Hysteresis + 1.5% of reading or i 1 mm Hg, whichever is greater
Excitation Impedance 350 ohms + 10% with typical Baxter Monitor Cable attached
Signal Impedance 300 +5%
Zero Offset <125 mm Hg
Zero Thermal Drift ~<10.3 mm H~0C
Output Drift 11 mm Hg per 8 hours after 20 second warm-up
Sensitivity Thermal Drift < 1 0.1 %/~C
Natural Frequency 40 Hz nominal for a standard kit (48712N); >200 Hz for transducer alone
