Hi,
Does anyone recognise the item in these two photographs? It came in a box of bits with my recently acquired part-built Europa. It looks like a temperature probe of some sort, but apart from a temperature range, and a small battery compartment, it has no other external markings
I would be grateful if someone can tell me what it is , and what the pinouts are.

Another question - The "Add Attachment" doesn't appear to work for uploading these photos, hence I have posted Dropbox links. Any idea why ?
TIA

The first one is part of the carb heat kit from Skydrive. It displays coolant temperature at the carburetor, but only up to 50C.
The second one seems to perform the same function but have no idea why you need 2.

Another question - Why can't I upload these jpg files directly ? I tried "Add Attachment" but it doesn't appear to work, so I have displayed them as Flickr Files.
TIA

Bob, It looks like an inexpensive battery operated temperature gauge. I have a very similar, possibly identical one giving me air box temperature. I seem to remember it cost about £15.

Hi Bob,
It's the temp probe and (LCD?) readout for a SkyDrive carb heat kit http://www.skydrive.co.uk/proddetail.asp?prod=CH-912-3
The Mk2 kit was milled aluminium with AN fittings and so had room for a drilled hole to take the probe; the current Mk3 kit has copper (brass?) tubing encased in a cast ali body with no room for a probe.
I have the Mk2, but discarded the probe (and standalone readout) in favour of the SkyDrive water temp kit
http://www.skydrive.co.uk/proddetail.asp?prod=WTG-912-3
whose readout can be fed into a Dynon Skyview (other EMSs are available).

Thanks for all the replies.
My Europa does have a Carb Heat kit fitted, and from Paul's description, it is a Mk.2
I'll change the battery, and have a play with it, but I have already fitted the Water Temperature adapter from Skydrive, and plan to get a Dynon Skyview Panel to monitor, amongst other things, the Water Temp. I understand from elsewhere on the forum that Rotax do not fit a probe for Water Temp, but rely on Cylinder Head Temp for engine monitoring. I would like to keep an eye on the Water Temp, so have used one of the two Cylinder Head Probes for the Water Temp.
This means at present, I will only be measuring CHT at one cylinder. Do other do this, or fit 2 or even four probes, and measure each Cylinder ?
Is there any advantage in having both Water Temp, and Carb Temp (by using this probe ) ?
Sorry for the initial confusion, both photos are of the same device from different angles. If it is self powered via the battery, any idea what the pinout connections are for ?
TIA

Hi Bob,
If you are using 50/50 water glycol mix it is a requirement to have both a
CHT gauge and a water temp gauge. The engine limitations have different max
temps for each. Most owners only have one CHT sensor. The very latest
engines have a modified location for the CHT sensor which should remove the
need to measure both.
If you have the carb heat mod there does not seem much point in measuring
carb temp. The reason you would measure carb temp is to warn of carb icing.
Regards
Brian
