    Are load cell signal conditioners limited to sample speeds?

    I found this; http://www.mechtechplace.net/mech-tech-electronics/building-a-low-cost-strain-gage-load-cell-amplifier/ All my problems are solved! (hopefully)

    Power supply for multiple devices -- effects on accuracy

    Hi, For my project I am plotting a Force vs Displacement graph using 2 analog inputs which are going to a DAQ. The two analog inputs are coming from; -A 5k potentiometer (for the displacement) -A 1000 lb load cell sensor (for the force) I would like to use a regulated 12V DC (1Amp) power...

    Are load cell signal conditioners limited to sample speeds?

    Thank you for the response Baluncore, The voltage source I am using is a regulated 12V DC power supply. Here is the link if needed; https://www.amazon.com/gp/product/B00K93AYTK/?tag=pfamazon01-20 Is it safe to assume that "regulated" means stable? If I'm not mistaken the maximum output...

    Are load cell signal conditioners limited to sample speeds?

    Hi Baluncore, The reason I would like at least 300 samples per second (I said 350 earlier but I meant 300) is because I would like acquire an accurate plot for my project. The end goal of my project is to achieve a Force vs Displacement chart. The force comes from the load cell while the...

    Are load cell signal conditioners limited to sample speeds?

    Hi, I need to buy a bridge amplifier for my load cell. I need to be able to take at least 350SPS (samples per second). The only load cell amplifier I can find within my budget states that it has a selectable 10 SPS and 80 SPS output data rate. Heres the link to the amplifier...

    Can I acquire the shaft position of my motor using my VFD

    The project I am working on is to design the control system for a shock dynamometer. I am using Labview and communicating to the VFD using Modbus. The shock dyno will look a little something like this; So one of the main objectives in my project is to produce a plot as seen below; The...

    What materials do I need to wire a VFD?

    Hi everyone, I am part of a senior design group that is building a dynonameter to test shocks. We are ordering parts tomorrow morning and so I want to make sure that I am not missing anything. I do not have any experience with VFD's or three phase motors but I am doing my best to research and...

    Do I need a feedback card to acquire motor RPM from a VFD?

    The VFD I plan on using; DURApulse GS3 series AC drive: https://www.automationdirect.com/static/specs/gs3drives.pdf Model: GS3-22P0 The feedback card accessory for the VFD: https://www.automationdirect.com/static/specs/gs3fb.pdf Hi everyone, I would like to know if I need this feedback card to...

    Is this Variable frequency drive compatible with this motor?

    The VFD I now plan on using is; The DURApulse GS3 series AC drive (Model GS3-22P0): https://www.automationdirect.com/static/specs/gs3drives.pdf It has a rated input current of 7.6Amps. The fuses available for this model come in "Fuse kit" pack of 3 that is to be installed in the drive. The fuse...

    Is this Variable frequency drive compatible with this motor?

    Thank you very much for your response! The shop that the VFD will be powered at has three phase outlets that are 250V 50Amps. Can I use these outlets to wire my VFD for the low voltage wiring (230V)? Or is the 250V too much voltage? Thank you.

    Is this Variable frequency drive compatible with this motor?

    My senior design adviser told me that the VFD must be the same brand as the motor that is being used, I'm not sure I believe this. I plan on using a GS1 series AC drive, here is a link; https://www.automationdirect.com/adc/Overview/Catalog/Drives/GS1_(120_-z-_230_VAC_V-z-Hz_Control) Here is a...
