Does size of air bubble affect MPXV5010GC7U pressure messurementI've replaced the water in the dogie squeaker with 100% silicon oil with a small air bubble in a 4mm tube into the MPXV5010GC7U sensor. Will the amount of air affect the sensor output?
Re: Does size of air bubble affect MPXV5010GC7U pressure messurementDoes a smaller initial air bubble between the 100% Silicon Oil and the sensor increase or decrease the output?
The size of the air bubble does not seem to change while the readings are decreasing.
Re: Does size of air bubble affect MPXV5010GC7U pressure messurementAir bubbles do indeed affect the output. The phenomenon of slow decline is very likely caused by air bubble compression or slow pressure relief in the liquid system, rather than a fault of the sensor itself.
Re: Does size of air bubble affect MPXV5010GC7U pressure messurementSince my original post, I've disassembled the housing and found a massive air bubble at the top of the squeaker. I've redesigned the housing for a new filling technique that insures that there is no air left in the squeaker and only the air bubble to the sensor. When I started up, everything look fine when I applied 200 grams calibration weight to the sensor. However, the readout from my Android Nano decreased from '0800' to no reading (reading is below the cutoff) over several minutes. What could be the problem?Re: Does size of air bubble affect MPXV5010GC7U pressure messurementAllow me to rephrase...how will the size of the air bubble affect the output?Re: Does size of air bubble affect MPXV5010GC7U pressure messurementHi:
Yes, the air in the tube will affect the sensor‘s output you know the MPXV5010GC7U is a pressure sensor designed to gauge pressure.
Re: Does size of air bubble affect MPXV5010GC7U pressure messurementAnother MPXV5010GC7U should be used to test for comparison.
Re: Does size of air bubble affect MPXV5010GC7U pressure messurementa new sensor to test again
Are referring to another MPXV5010GC7U or a different sensor?
