Delta Pulse

[salim]

salim, what you know about precision resistors?
are you need in precision information about the resistors, learning course etc.?
have you read all this thread in details?

hi
please explaine more about "precision resistor" have you found error in my project? ===> im using this coil just for testing i will make tested coil later

precision resistors color code

http://www.resistor-color-code.com/color-code-chart

Violet 7 7 7 10M 0.1% 5 ppm

you see - they are EXISTING! not 10%, not 5%, not 1%! but 0,1%!

0,1%

Hello Salim
According to the photos of your project, there are possible errors in your PCB.
Check with a tester:
Shorted tracks
Open slopes

Hello KT315

I have some question

1- do you have protel file with pcb format ?

2- wich part list did you used ?

3- With one is better for depth detection 100HZ or 300HZ or above ?

4- How mouch is the maximum depth detection with 1*1 coil ? (Object Dimension)

Thanks...

For big objects detecting it is better the frequency of 100Hz

Detecting distance at air.....
Mikron wrote when had the Delta Pulse in production..

With coil 1x1 m
Metal plate 25x25cm at 1.8 m
Metal plate 50x50cm at 2.6m
Metal Plate 1x1m at 3.5m
Maximum distance 4.5m

Hi.
I have the pcb from XR71p.
Exactly the same detector

done special schematic for Persian people.

thanks for help with my current configuration i detect coin at 15 cm only i will tay to find resistor with 0.1 %precision
nota: (im not persian im tunisian)

hi
for all how make sample side pcb by elbombacı i found a little mistake mentioned by hl54 p 19 (8.2v missed) i guess after making this jimper your detector will be more sensitive i will poste result wen i return at home

Hi all.
This is my first post on this forum.
Now, I*m starting to work on Delta Pulse, and I have some question.
Anybody can give me speedy reply?
I*m looking for pcb by KT315 in sprint layout software.I need it , to made pcb in professional firm.
Best regards . Wies

Is born!

Is actually the second ‘cause the first was an experiment.
I made the coil according to the indications of bbsailor but I used telephone wire covered with polyethylene which has a dielectric constant very similar to Teflon but is more easily found.
The container has both the front panel that the base aluminum and this caused a problem when through the headphone jack these were connected to ground. The metal detector was very unstable, singing like a canary, especially touching the cable (RG 59) and the front or rear panel.
For now produced about 3.5 euros in its first hour of work on the beach ...

How to create a better coil delta pulse ?

[Jose]

Hello Noemio
Try the following
To ground the front panel and aluminum rear (+).
RG59 mesh must be connected to ground (+).
Shorten and twist the conductors between the plate and the connector of the coil
