Topic: Barani MS Pro vs SmartCellino radiation shield comparison

[ypsinine]

Personally I recommend leaving the filter but, given the low quality of the one supplied with the EP sensors, to provide for its replacement no more than every 2 years, much then depends on the place where they work.

M.

Interesting. I am thinking to put the filter back on when I receive the S+M.

Do you know an online store that sells better filters for the EP sensors?

I don't know in your country but a a simple research on Google with "PTFE filters" Will give you all you need

Again, what does absolute humidity outside of the shelter have to do with comparing a Barani MS Pro with a SmartCellino shield? @Bianconero (and Toby to a lesser extent), I’ve asked multiple times to stop the off-topic talk and yet you continue to spam the thread with it. Please just stop and open another thread if you really want to discuss this.

  simply don't focus solely on T if you want to make a relevant comparison at your level (the rest we'll forget) so if you haven't understood the ‘objective of absolute humidity is to separate the measurement of humidity from the influence of the temperature error of the shields/sensors.
Well, it'sclear that with the massive T probe in your ‘Belgian’ station, you'd have to measure practically every second to compensate for its slowness and the inertia of all the matter that influences the measurement.
It is also to determine whether a shield accumulates dew or condensation overnight, which should be visible in absolute humidity measurements.

clearer than that sorry but I couldn't/no more

The thermistor I use is temp-only and this has been made clear multiple times so I have no idea why you keep mentioning humidity, it is literally completely irrelevant to the thread. To say the comparison isn’t relevant bc I don’t have a humidity measurement is pure nonsense. I’m honestly getting a little tired of all this now, it can’t be that difficult to just stick to the topic of the thread.

My data from yesterday

I add a file that may seem OT and I apologize, but it is linked to a request made a few messages ago

It is the comparison, of yesterday, of temperature and humidity of the 3 sensors with different types of filters, the sensors are inserted in a Comet f-8004 solar screen with provision for 4 sensors, the sensitive part is at the same height.

- sensor without any filter
- sensor with sintered steel filter (Rotronic production)
- sensor with original ecowitt filter with about 1 year of exposure

I hope it can be useful, it has no scientific value, a much longer comparison with screen rotation would be necessary, it is just an idea of ​​the differences on a typical autumn and humid day.

I'm going to answer that my compatriot won't be happy (humour). 
Anyone who wants to can transfer there:
https://www.wxforum.net/index.php?topic=47127.0
To find what I regularly see in Portugal you typically need high humidity, radiant sunshine and little wind.
On Sunday morning I found the same conditions here in Belgium, so it's clear that the environment is a determining factor.
You're unlikely to find the same conditions in Switzerland (for example).
If I can find a slot before I leave for Portugal on Saturday, I'm going to fit a new EP and an unfiltered SHT35 in the same new Pro3
(I hope that the fact that the Pro3 hasn't been run in won't change the situation).
This point has also been overlooked, although 3 of us have had this problem.
Because of the large volume of the Comet, it may not be the ideal shelter for trying to reproduce this type of situation.
Also, the design is different, and the double domes have a lot to do with it; I have the impression that the black domes prevent thermal bridges.

[mauro63]

but I wonder, why don't you use the post already proposed for all yours ramblings?
Is it that difficult for you?

  Maybe it's just because you're also the one who comes to talk to us about the Comet, no? or my AI sometimes has bugs 

As a reminder, on your national forum, it wasn't demonstrated that this shelter had an air ‘evacuation’ problem (a phenomenon amplified with the SHT31 Davis) or am I mistaken?

Fluid mechanics is just a bit of rambling for your purist knowledge ? in the field okay those who try to measure correctly with averages /1 mn with constant 20s/1m/s, anything that is not capable of reacting as well, is by definition wrong in relation to this target reference. 

I'm not going to insult you by giving you a whole bibliography unless ......

Let's not even talk about your ‘sponge’ sensors and/or a Belgian PT with such a large 5.8 mm sheath capable of obtaining this constant 20s/1m/s in air with a thermistor in it

Anyway, I'm going to ramble on one last time, but I'm curious to know whether any ‘submariners’ reading this discussion about your new product would agree that smoothing out already slow equipment on top of fast equipment to see that it sticks on average completely distorts the real weather measurement ?

That's the question 

I only referred to the Comet for the purposes of comparing filters, as I have no other screen designed for such a comparison.

Go ahead...

You really just have zero respect for other people’s wishes, don’t you? How many times have I asked you to stop rambling about irrelevant stuff and you just continue on, unimpeded.

[Jasper3012]

Hey guys, what are we talking about? ( too lazy to read all the comments )

We’re comparing the widely known Barani MeteoShield Pro with the new Italian shield “SmartCellino”. There’s been loads of unwanted and irrelevant comments so sorry for that, but the thread on the whole is definitely worth reading.

Thanks! Hopefully we can finally get back to the topic of the thread now. I’ll post an updated version of my stat table this eve.

Looking forward to it. With stat table, do you mean from the start of your comparison until now?

Yes, min, max and mean for every day from both shields. There probably won’t be too much to see to be honest, the shields are running very similar.

True,

I can confirm it, even though, as already said, my station is not particularly reliable, the data that are really interesting, namely the meteorological ones, are extremely similar.

There are aspects that still need to be explored further but, in general, SmartCELLino manages to return reliable data and in line with similar products.

In the objectives it is a screen created to make up for serious shortcomings in the professional field, I am talking about Italy of course, where old-design screens affected by obvious errors are still in use, or as an alternative in the amateur sector, also being able to count, in my opinion, on a good quality/price ratio, also considering the equipment of accessories, certainly not common

October, updated until yesterday

There we have it, a mere 0.01C difference in mean between the shields over the past 21 days.

Allow me a hint of envy for your temperatures, here we could still go swimming on the sea

sorry for the OT

[Kallo78]

Data from today until recently

In the black circles, around 2 o'clock in the night, I think we can assume that the sensor without filter was "hit" by a breath of dry SSW wind that has monentaneamente made raise the temperature and reduce humidity.

After a night with 99% humidity in the orange circles, you can see that the sensor of the Siap, inside its filter, remained wet for longer than the other two and especially the sensor without filter which obviously "dried" first.
As the radiation and also the wind grew, the sensors were progressively aligned

Haha, the temperatures here are nothing to be jealous of, they're shit. I'd much rather have a more continental climate with a proper, snowy winter. But it is what it is. Funnily enough, I noticed the temps you are having this October are more like what I get in July! The Belgian autumn is a very poor time for radiation shield testing, it's increasingly dark, windy and with regular cloud/rain, giving little difference between shields. But at this point, I'm honestly not sure there'll ever be significant differences between the shields, even in more "interesting" conditions, like a calm and clear morning or evening. Time will tell, as ever.
