Delta Pulse

[Geo]

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
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
br!

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

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%

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
thanks for all for help my delta pulse work very well i have just to connect tune contact for coil im using degoss coil for 15" pc screan

found that the LEDs are in their correct position

hi
can you help me to determinate the value an referance of this part im confused

thanx br!

last 3 are:

15nF (or 0.015uF or 15000pF)
1.5nF (or 0.0015uF or 1500pF)
1nF (or 0.001uF or 1000pF)

Werry nice..

hi finaly i finished my delta pulse my first home-made detector but is not working

1- i have contuned bip with or without coil
2- i used 22k instead 20k and 49k instead 50k
3- i havent 8.2v in zener diode
4- i havent oscillo and for multimetre i have to connect coil for mesurement ?
5- im using 12v 1.3a thant is good ?

please help me to solve my problem sorry for my bad english

Dose your delta has sensitivity to gold and copper ?

Thanks ...

Is there anybody to know that how calculate the
Formula of making coil ?
Iman Boroumand.

One of the best coil calculators can be found in the MiscEl program (try Google). It has lots of different coil options.

There was a bug in the old version and it would sometimes not accept inputted data even when the instructions were followed. A newer version is out so maybe that has been fixed. Use a leading '0' in a number like 0.254 to avoid problems.
