Hello all,
My name is Keyhan and its my pleassure to be here :angel:
I hope I asked my qustion in the right place
We're working on the new project at Wall Boiler category,
we wanna make the 10K immersion sensor that used in wall-hung or standfloor boiler.
we need some information like as :
1-The best material for glue and metal part
2- about sensor
3-about Connector

is there anyone help us or work with us ?
Thank you

Why re-invent the wheel here? Immersion thermistors already exist, heck you could even just use a coolant temperature sensor for a car since it would already be designed for these exact conditions and have a sealed electrical connector.

I found a page worth of those sensors on Amazon alone.
The sensor you seek to build already exists.

X2- also are you hell bent on an immersion well? If it's a wall hung I'm gonna go out on a limb and say the primary loop or really wherever you plan to put it pipe is a little smaller than typical immersion wells- at least that I'm accustomed to- if you find one make sure you get some heat transfer compound like Honeywell 107408- other wise a tightly strapped insulated 10k Bead in all reality would work just fine

I don’t understand the question.

Are you asking how to make a sensor?

Just buy one.

Or are you asking how to take a sensor and mount it in a well?

Buy a well, as close in diameter(slightly bigger) then the sensor, and smear the sensor with heat conduction paste and insert into the well. No glue required.

Better yet, what does the MFG of the boiler say to do - follow that.

Thanks for answer
We want produce this kind of sensors for wall-hung boilers.
you told some information about that. i didn't understand well.
You told about "Heat Conduction Glue" ? Do you mean something like as silicon glue?

 

[keihancpu]

Dear all
we want produce this, Not buy it.

 

[rider77]

Should your company have an engineering department to design such a thing?
What boiler manufacturer are you with?

 

[dave1234]

Dear all

Your quest after ingenuity is admirable but I really think your gonna spend more in the long run not to mention valuable mind time- retract what i said earlier about immersion well and pipe size concerns and tee and bush the end of loop for your well and thermistor from any controls supplier

Not glue. Heat conductance paste.

Its very similar to Anti-Sieze compound.

Essentially it fills the gap between the well and the sensor to transfer heat.


I have no clue how to build a sensor.

Damn straight- similar yes- but even harder to clean up then aluminum based anti-seize. I provides the Honeywell part number in previous post. Messy stuff- I light dip of sensor before putting into well adequate- otherwise it'll puke out and better have some good gojo or whatever wipes

I'm confused- are we trying to manufacture a boiler? Pretty much all OEMs use at least some licensed products from other manufacturers even though they may stick their stickers on them. I mean look at stainless condensing boilers. The heat exchangers are all the same made by the same manufacturer from Germany I believe. I mean what's the end game? I'm not being facetious so forgive me if I sound that way but are looking to manufacture a gas valve from scratch next? UL=$$$$$$$$

Dear
We dont want to produce boiler.
We just want to produce the sensors where located at the wall-hung boilers.
I cant send link here, if you search "NTC Wall boiler", you could see the picture.

Really thanks for your answer.
so the material that fill the gap is heat conductance paste.
So
1- We have to produce metal part.
2- We have to buy sensors.
3- We have to place sensors in metal part with heat cunductance paste.
4- We have to produce connectors.
5- We have to connect connector and sensor.

Note: You can See the picture of NTC that we want to produce by searching google " NTC Wall boiler"

Do you have any recommendation for No 1 & 5

Thanks

Dear
we just want to produce a simple sensor, Not a boiler.

Everything that you need to accomplish your task is already being manufactured.

Simply find suppliers for each individual component, purchase them, and assemble them.

 

[keihancpu]

Thank you dear
my question is how to assemble them ?
my question is about the way that we can assemble them with a cheapest price.
