Hi all, I was thinking of rotational calibration of a two Dim. compass. I understand that while I am rotating 360 degree I have to keep the compass flat level...
Hi John: I have a wrist watch that has a bubble level on the face that you need to keep centered when you use the electronic mag compass, so they don't worry...
Dear Brooke, Thank you for your valuable information. These now days, I do not think that people would have add bubbles anymore. I think accelerometer would...
Hi John: I guess it depends on where you are. Here in Northern California, and I guess most of the U.S., the Earth's magnetic vector is stronger in the up -...
Here are some other ideas John, Without an accelerometer: If you have access to the mag X-Y signals you will notice that if you tilt the compass the vector sum...
Greetings all: I have a Torsion Balance mag up and running well using a 1/4" X 1/4" X 4" Alnico 8 magnet suspended with a 14" long 0.008 guitar string. ...
Hi everyone; I'm a mechatronic engineering student and I'm trying to produce digital compass with Phillips KMZ51-52 sensors. Digital compass will be assembled...
Hi Sinan: You might want to have a look at the Daventec CMPS03. It's a PIC based compass using a couple of single axis sensors, but no tilt compensation....
Hi Sinan, The following example might be suitable for your project. You can find the hardware and software related to your topic. In this ap note HMC1052 is...
Hello Gentleman, In reference to the HMC1052 there are two arrow that represent A and B sensor and are orthogonal to each other. If one places this IC on a ...
Hi all! ... Quite a while ago a member posted, that he used the KMZ sensors, but then switched to the HMC Honeywell sensors, because those have less noise and...
Hi everyone, I just thought I should introduce myself to the group and share a bit of background on what i'm doing before I get going here. My name is Rob and...

Hi Rob: You might try eBay for "Schonstedt" To learn why search my web page for the same word: http://www.prc68.com/I/FGPat.shtml Have Fun, Brooke Clarke ...
John, thanks for the response! In regards to your message, I suppose you are right that it is not "truly" necessary to have two sensors gradiometrically to get...
Hi Rob: It's very important that whatever you use to hold the two sensors keeps them perfectly aligned. For a gross example if you used a 10 foot length of 1"...
OK, the parts kit is here and my "Dead Micronta 4001 metal detector to dual FGM-3 gradiometer mag conversion" project is now officially underway... :) I have...
Rob, There is no "reset" function on the SCL-007. Pin 18 is labelled RESET because it is, in fact, reset by the input from the other FGM-3 sensor to obtain the...
Hi: I've received some sample ring cores that may make good fluxgate magnetometers. The metal has an OD of 1/2", ID of 3/8" and height of 0.111" The...
Hi all, Has anyone noticed a slow gradual long term drift of their magnetometer ? I've been monitoring this for Months & not found out what is causing this...
It may be moving slightly relative to the earth's field. Have you getting a lot of rain there? If it's buried, the ground is expanding slightly as it absorbs...
Hi Erich, No, my magnetometer is inside the house on a sturdy shelf, checked for signs of the bracket buckling & such but even that seems ok. Thanks for your...
In the past I've tried to obtain a couple of sample PNI magneto-inductive sensors (the unshielded leaded variety), but they were asking something like £20...
As I am one of the developers of the PNI technology I can tell you for certain that the sheld is an EMI shoeld to try and keep radiation from the coil to a...
Ah - so it's to prevent RFI emission ... Thanks a lot John - appreciated - that's the kind of explanation I was looking for. There was zero info in the data...
Rotational calibration is available in almost all compasses. It is a simple math routine. Even the fluxgates use it. I fyou want any of the math to make the...
