  1. Re: Need help for selecting sensors for deflection measurement

    Hello. I am actually doing a minor test with a strain gauge mounted in a quarter bridge configuration and I was provided with a strain gauge amplifier. the amplifier and corresponding circuit is as...
  2. Re: Need help for selecting sensors for deflection measurement

    Thank you for the reply. However, I am not sure I can have access to different material types and moreover perform tests for their properties. I am actually carrying out a trial with strain gauges...
  3. Re: Need help for selecting sensors for deflection measurement

    Thank you for the guidance. I shall study the possibility of using the second option that is line laser.
  4. Re: Need help for selecting sensors for deflection measurement

    Hello again. I have been looking at some strain gauges on the net but most of these are for mild steel or aluminium metals. My prototype blade is of plastic and I am wondering whether it will be...
  5. Re: Need help for selecting sensors for deflection measurement

    Thank you very much for the help!!! I will implement the prototype and start testing by next week. I shall drop in few words about the results.
  6. Re: Need help for selecting sensors for deflection measurement

    Can flexible force sensitive resistors be used as an alternative?
  7. Re: Need help for selecting sensors for deflection measurement

    Thank you very much for the various options proposed. I would tend to divert more towards the strain gauges option. However, one of the problems I am facing is that the model is very reduced with the...
  8. Re: Need help for selecting sensors for deflection measurement

    Thank you for the reply. However, i will need sensors that can be placed along the blade length and not at the blade roots so as to investigate the effectiveness of this kind of measurement. Once...
  9. Need help for selecting sensors for deflection measurement

    Hello!. I am currently doing my project on pitch control of a model wind turbine. I need to vary the pitch with respect to the deflection of the blade but i don't know what kind of sensor I can use...

    Re: Trying to operate the MG1501 rc servo

    The servo is powered externally with 5V. Unfortunately I have not been able to carry out all these tests since the lab is currently closed for Easter break. But i have tried the original program and...

    Re: Trying to operate the MG1501 rc servo

    Hi. I actually found my mistake and the servo was moving fine for some time when i executed some simple algorithms to generate different PWM. I downloaded another set of codes whereby the servo is...

    Trying to operate the MG1501 rc servo

    Hello. I am trying to operate the MG1501 rc servo from an mbed controller pin which provides 3.3V but it is not working. I previously tried same with a GWS S03N STD and it worked fine. Can anyone who...

  15. Question(s) Stationary/ Rotary interfacing for power supply and signals in a prototype wind turbine

    Hello. I am currently doing my project on pitch control of a prototype wind turbine. I am using individual pitch control and hence need to place one small servo motor for each blade. the angle of the...
