Thank you for your responses. The goal is to be able to detect pipe vibration from above the ground level. Therefore, accelerometers and capacitance sensors...
Dear all, I've been reading about different 3D compass units. Some of them requires two type of calibration, XY and XZ and some do not require any calibration....
Hi John: For what purpose? In what quantity? If small do you have a way to attach the package? What is the delivered price for each? Have you compared the...
Seeing as it's been quiet here for a while, maybe I could enquire what the latest thinking is regarding the ultimate cause of the earth's magnetic field ? I...
Hi everybody my name is Milo, I hope you are all well. I am very interested in magnetometers and I have some questions regarding them. Sorry if some of my...
Since you have a UK address, I would check out the gradiometer kit at Speake & Co. in the UK. Their web URL is: www.speakesensors.co.uk They are on holiday...
You may also check out: www.stefan-mayer.com/Lcsing.htm I am running a fluxgate of this company for a year now for monitoring earths mag field and its highly...
Regarding temperature stability of the Speake FGM-3 and FGM-3h for monitoring the earth field fluctuations. I sealed mine in a length of PVC plastic pipe and...
Hannes, I got a so called FL1-100 from Stefan Mayer. This is a 'special' he usually doesnt carry (for one component mag field measurement) - so please ask him...
Hannes, nearly no interferences from that. What is really disturbing are cars moving to and from near parking lots and so changing the 'static' mag field. For...
... Hi Ernst, that's cool! In my experiments a while ago, I had big troubles with TV, computer, washing maschine, stove etc... But I was only experimenting...
Hi Everyone, I am leading a team of engineers building a hand-held inertial navigation sensor and we are considering using magnetometer-based electronic...
Hi Victor: You may want to research existing systems for locating things in that or a similar environment. I think there are radio based systems that would...
Hi Everyone, Well, I can't give everything away since the design is company confidential. What I can say is that we are developing a 6-DOf inertial sensor...
Hi Victor: If the magnetic sensor comes near any ferrous metal, like a mike stand or musical instrument then it's heading will change. The magnetic field...
... First of all, you should measure the actual magnetic field. This will end all your fears. Then, if this magnetic field is strong enough AND you know the...
Hi Hannes, WOW !!!! Those pictures are fantastic, wow really on the edge of space. Cheers, Mark [Non-text portions of this message have been removed]...
Hi all, i'm currently doing a 3-axis magnetometer using 2 HMC1022 chips. However, i'm unsure if my schematic design is appropriate. Can somebody shed some...
Hi, Yes I am using it to detect the variation in Earth's magnetic field Best regards Emmanuel O. Abe +234(0)803-447-4604 Physics department, Federal...
Hi, Well the circuit you have posted has nowhere near enough gain to detect the disturbances in the Earth's magnetic field, the gain feedback resistor on your...
Actually, i´m searching for a schematic of a gradiometer, using Honeywell ICs, so I´m open to some advice od idea about it. Anyway, there are two eyes...
