Barani MS Pro vs SmartCellino radiation shield comparison
« on: October 07, 2024, 04:03:58 PM »
Hi all

Smart Cellino shield arrived today and I put it up this evening. Thanks to Mauro and the company! Very impressed with the package and its contents. I’ll take a daytime pic later this week but this is how it’s looking. Same sensor, same height, same everything… so it shoud be a very interesting test. I’ll update this thread quite regularly and especially if there’s something noteworthy to report.

Everything can be followed live here: https://meteo-be.net/nl/grafieken/male-brugge/last_24h

“Temperatuur 2” is the SmartCellino, the first graph is the Barani.
 The “temperatuurverschil” graph is especially interesting, as it shows the difference between the shields (blue = Barani cooler, red = Cellino cooler). You can ignore the data from that graph from the previous few weeks, the second sensor has been functioning as a grass sensor, so there’ll obviously be a large difference between that and the shielded sensor.

UPDATE: the SmartCellino shield is now the first graph on the link provided, the Barani the second.

Thank you, especially for your patience in bearing some annoying delays for which I apologize again on behalf of the Company.

I will be happy to follow your tests and have your important evaluations.

Jasper,

I've read through the whole "Barani too good to be true" thread. If one ignores all the repetitive talk from certain individuals there is actually some good info in there.

My station is located inland in Sweden and we rarely have much wind. I think I have noticed the "Barani effect", i.e. overheating during solar radiation from the side during no/very little wind, both in the morning and during the evening. I often compare to stations nearby (both official and amateur) and for some reason the temperature at my location is basically always higher. This could be due to microclimate of course, but it seems to be too often for that. Now, it seems the SHT35 is a quality sensor so I don't believe it is it because of the sensor either, but rather the Barani. If you are interested about the setup there is a picture in the About page on my website.

I am very interested in your tests here, particularly during no/low wind scenarios. Going to be following this thread for a while. And very cool that mauro63 is working with the manufacturer.

I really appreciated the pictures of your installation, it is clear that it was made with care and attention.

Excellent choice to separate the rain gauge, to place it low, in order to reduce errors due to the wind, perhaps I would lower the lightning sensor, it is not necessary to be so high and as it is now it could create turbulence and interfere with the wind measurements.

Fair point, I thought these would benefit from being high up due to the roofs of the buildings around here, but maybe not...
I am going to take the WS80 down for a FW upgrade now so I will lower the lightning sensor a bit at the same time. Thanks for your input!

edit: Unfortunately I was not able to lower the lightning sensor, because the metal pole is too thick (except at the top where it is mounted, which is 5mm less in diameter than the  rest).
So I now remember why I put it where I did back when I mounted this whole thing.
Anyway, I don't think it interferes too much with the wind sensor, the top of the lightning shield is lower than the bottom of the wind sensor so at least it's not directly in the way.

Hi Ypsinine. The effect you speak of is in fact a thing with the Barani and sometimes even to rather dramatic effect. I’ll add a graph showing the difference between the Davis FARS and Barani MS Pro on the 27th of Aug this year. A positive number/the red values represents the Barani being warmer than the FARS. You can see that during the evening, there was a dramatic spike in the Barani’s temp, where it got up to 2.1C warmer than the Davis. This did in fact occur during the no wind/low sun angle combination. I had the Davis and Barani side by side for about 4 months and this effect occurred every now and then, but it only got over a 1C difference about 3 times and this 2.1C was the worst it got. You need quite specific circumstances for this to occur, a low sun angle but like 5-10 km/h of wind and this pretty much doesn’t occur, beside maybe a few tenths. I’ve not been that bothered by this effect since it pretty much never affects the min/max (due to the time of day it occurs at), but I can see this affecting the max quite a bit more often in the Swedish winter, due to the very low sun angle and added snow cover aswell. I don’t see this being of particular importance in my location/climate, as there’s cloud/rain/wind most of the time in winter, but in certain locations, I can see it being a rather big downside to the Barani. I hope that I can find out with this latest test if this new SmartCellino shield suffers from a similar sort of thing, or whether it does a lot better in that regard. Time will tell.

What the actual values looked like at the time. You can see what I’m talking about with it never affecting the min/max, but still, a big error nonetheless. You can ignore the “+10cm” on the graph.

How the two shields are comparing since midnight. Again, red = Barani warmer. Hardly any difference. There has been quite a bit of wind and sunny spells, conditions in which the Davis FARS would quickly start to run a few tenths too warm, but this hasn’t been the case with SmartCellino today. Early days though, of course.

Barani: min 13.4C max 18.9C
Cellino: min 13.4C max 18.8C

Report yesterday. In the morning to the activation of the hot wind from the south SmartCellino reacts with some delay, as happened already other times.

I'm going to raise a few eyebrows here, but the worry on this day is the humidity. A HA calculation would be nice.

Nice setup! I noticed on your attached file that the SC (SmartCellino) was lagging behind the other shields by quite a bit just before sunrise. Is this a common effect with the shield?

Overcast with a moderate wind and a bit of rain today so very little interesting to report. Both shields with a 13.2C min and 15.7C max.

It will be interesting to see how these shields cope with side radiation and low winds. The helix in Barani s may act as a disadvantage here.

Hi, it happened before but in slightly different conditions. It is not said that it is a characteristic of the Cellino, I was probably hasty to evaluate the chart. They could also be a reaction of the Barani (by the way there are two in position). As you know the truth in this field no one has, we continue to observe.

Dead weather again here today, typical autumntime cloud and rain with little to no difference between the shields as a result.

Seeing some evidence for a slightly faster response time in the SC vs the Barani… Quite a bit of short peaks and troughs in the temperature last night due to clear spells and the SC reached a temp 0.4C higher than the Barani in one of those peaks (9.1C vs 8.7C). I often saw this with the Davis aswell, it would drop faster at night in clear sky but also rise faster as soon as we had a bit of cloud. I suspect the response time in the SC won’t be as good as the Davis, since it’s still a passive shield, but maybe it’ll be slightly faster than the Barani.
