Force sensor

(1/3) > >>

hazzer123:
Part of a project i have, is to electronically detect when an asthma inhaler valve is fully compressed. Force exerted on the valve is created using a stepper motor connected to a ballscrew, which is in turn connected to an arm which pushes the top of the canister.

I can not seem to find a good suitable force sensor for the job. Has anyone any ideas where to get one from, or even maybe an idea for a new method of detection?

Hi
Is it strictly a function of force? or is it also a function of position (limit switches).

It sounds like you want a limit switch, not a force sensor.

But if what you want is a force sensor . . . what forces are you expecting? What accuracy do you need? What is your budget?

Ive bought force/torque sensors from:

(and one other I cant remember at the moment)

Hi

i don't think its a limit switch i need, since the machine is measuring unknowns. Its goal is to measure how far the certain canister needs to be compressed before its internal spring is compressed. The machine is for qualtiy control, testing a sample of a batch of canisters.

Force is probably going to be around 200N max
Accuracy - not much needed.
Budget - around $200

Thanks
