    Where can I buy low cost force sensors (preferably in Oz)?

    I'm trying to prototype a product that needs a force sensor with a FSD of
    about 10kgf.
    RS etc sell discrete strain gauges etc, but I am looking for a integrated
    sensor. Some thing similar to used in cheap electronic scales would be
    ideal. The price of load cells is way (weigh?) too high. Googling has not
    turned up any useful sources.

    Any pointers greatly appreciated.

    TIA
     
  2. Whats the application and how many are you chasing? I have access to some
    cheapish korean load cells. They may still be out of your price range
    though? I'll get you some prices if you are interested.

    Thanks for the reply Andy. The applications is for use in some training
    aids. Cost is a real issue - I'm hoping to track down something in the range
    $10 > $20 per unit. Accuracy isn't critical - better than 5% would be
    adequate. What sor of price are the load cells?
    I'm also looking at trying to locate someone who can supply some force
    resistors - I don't know much about them but I understand they are
    inexpensive.

    Regards
    Rob

    Why ? Its something others are interested in too.
     
  6. Does it have to electronic.
    A simple solution is to connect the clutch master cylinder from an old car
    and connect it to a pressure gauge. This system works well and has been used
    in many applications over the years. If you use a cylinder the has a 1 square
    inch piston and the gauge in PSI, then you won't need any calibration .You
    can then convert the PSI units to what ever you want by writing on the gauge
    with a fine pen.

    Because it's now a purchasing issue between the respondent and myself rather
    than being of a technical nature. I'm sure Andrew would be willing to
    provide you with model/pricing details if you are interested.
     
  8. YEP! My pleasure! CAS BCA-10L Single point load cell, approx 140AU dollars +
    GST. Can also sell plain ol' strain guages of the CAS variety if required.

    Some may just be interested in the general price/viability question
    without actually wanting to buy some themselves currently.

    There will always be some situations where cheap
    force sensors are the obvious way to do some stuff.

    Hi Andy,

    Can you supply details of the transducer .. I may have an application
    for one at work?

    Thanks,

    Tony
