Fluxgate proton magnetometer PPMA-3

[kt315]

hi geotechers.

new project had been released by TechnoID in Russia. sorry that I have not possibility to give you the schematic and .HEX file. one reason - it's NOT mine (say it for ivconic again especially). not my project, not my schematic, not my idea, not released by me. but IMO you need to be in course 'what is going on at outer', yes?

Like very much the STRONG and CLEAR construction of the unit...
Thank you for the photos

PPMA in a field. (photos are NOT mine!)

a sensor construction was taken from magnetometer MMP-203 sensor one. working environment is kerosene.

Hi,

Just a small precision.
This is obviously a Proton Precession Magnetometer (PPM) and not a fluxgate. They use completely different physical properties.

It is indeed quite a solid construction built from an industrial-type of enclosure. I wonder what is its weight.
From the video published on youtube, I see that the rate of reading is rather slow for a normal walking operator, about one per 2.5 seconds. There is some danger to miss potential targets as this corresponds to several steps of a slowing walking operator. In order to get a good target return, you need at least to make one reading per second.
There is also no indication that there is a data storage of the survey. It seems that the only feed back is aural and LCD. But I am possibly missing something.

The targets shown on the published pictures (some of them look like heavily rusted cannon shells) are so large and buried so shallow that I am sure a good PI detecttor would have easily detected them.

Anyway, this is at least one more of the very few PPM projects having produced an operatioanl instrument with proven results.
Is there any info published on the web by the authors?

Look at the web site of the author:
http://mikes.front.ru/index_e.html

That should not be the last schematics.
I sawb on the pictures that the display is an LCD.

Powering a PPM with 10 batteries of type AA should not last very long in the field.
40500 rub is about 1,310$

Thanks for the photos.

It looks like the sensor is based on this Geometrics design. Is
that sensor housing from a sump pump?

price is variable... $930-1200.

Is
that sensor housing from a sump pump?

thinking sensor housing done from ordinary PVC tubes, kinda sanitary equipment... 11 sm of diameter. it is not so much critically what you use for the housing...
