Pressure Simulator

OK, I thinking of it now. Got it? _{Think really hard. How to simulate pressure.}

Can you please be much more specific about what types of pressure you are trying to simulate and measure and exactly what your pressure measurement and/or calibration device is expected to do?

"Pressure calibration" alone is far, far to broad (is it point force pressure, air pressure, distributed pressure, external measurement, what accuracy, what duration, what size and shaped object, what's the object/medium characteristics, is your device electronic/mechanical/hydraulic/pneumatic, etc, etc).

Additionally are you building a test rig to both exert a specific known pressure on an object and measure it, or just measuring an external pressure with say a calibrated hand-held measurement tool.

Please provide much more information.

A machine for calibrating different types of pressure transmitter?

An internet search of "pressure transmitter calibrator" produced a number of helpful links to this still-to-broad question.

Does this help? If not could you describe your actual question and requirements/personal ideas/project spec/etc in much more detail! (I am assuming you are still looking for a final year instrumentation and control engineering project based on your recent posts on CR4).

yes, im sorry for being so vague, it's just half the time im clueless of what im talking about. Anyway thanks for the advice, im actually feeling the pressure right now cause we're closer to the deadline and am worried about not being able to graduate on time, it's good to know that there are people willing to help.

Please list the different types of pressure sensors and transmitters you want to calibrate, the methods of mounting them and the pressure ranges you want to read and then we can advice you how to go on about it.

Right now what I have in mind is a hydraulic cylinder operated by a hydraulic pump. It is equipped with several mountings for different types of pressure gauges and sensors and has a correctly calibrated pressure gauge.

Basically, you mount your sensor or gauge to be calibrated in the correct mounting point and pressurize the cylinder using the hydraulic jack. You then compare the reading with the one on the correctly calibrated pressure gauge (and possibly whatever electronic calibration device as well). It sounds quite simple and straight forward to me, so you better check with your lecturers in case they reject it like your previous automatic pest control system.

By the way, did you discuss my offer to you with your team members?
