Other Parts Discussed in Thread: INA326
I'm trying to design a circuit suitable to amplify the signal coming from the SDP-200D LVDT (from TML). I tried the three op-amps amplifier using LM324 but the circuit seemed unstable and works only for a small range of displacement.
The LVDT has a rated output of 5mV/V +-0.3%, the recommended exciting voltage of 2V or less, and the allowable exciting voltage of 10V, frequency response of 2Hz. The resistance between each of the Wheatstone bridge nodes is 263 Ohms (resistance of the strain gauges unexcited). I attached the file that shows the relevant information about this LVDT.
I was advised by an engineer to amplify the signal first then connect it to the data acquisition Q8-USB (from Quanser).
Can you please advise which parts/designs I should buy for our Lab. I have several LVDTs and accelerometers from the same manufacturer (they share the same specifications) and want to connect several ones at the same time, thus.
I thank you very much in advance.
