I work at a crash test facility and we use a lot of piezoresistive accelerometers. That being said, we need to be able to quickly check the functionality of the accelerometers before we put them in a car for a test. So I need someone to build a handheld device that can measure and tell me the resistance on both sides of the wheatstone bridge inside of the accelerometer.

@Bogdins

hi there, - even the device will be kinda universal, it will have to have some interchangeable "heads" to accommodate different type/size of cells - also on a handheld device will be quite difficult Relevant Skills and Experience This is Bogdan from Romania. I'm a mechanical engineer, 3D designer and modeler, working on product design, industrial design and prototypes. I have over 15 years experience across multiple industries Proposed Milestones $1250 USD - project do you have the dimensions (3d models) of the cells used?

I will save you heaps - if all you need is to measure the bridge then by a good multi-meter (fluke) or a good instrument test meter. If you need a g-force test rig let me know Relevant Skills and Experience Over 25 years of Automation and Control Systems Engineering What do you actually need? Proposed Milestones $5 USD - No Fee no obligation - simply tell me what you need $5 USD - Do you simply want to measure the bridge resistance? $5 USD - Do you actually need to test the accelerometers under a known g-force or set of g-forces? $1475 USD - Let me know what you want or need so we can discuss solutions Open a chat when you are ready
