Weatherspares.co.uk are currently selling the pre-2006 analogue T/H sensors
for
£65. They say the stock is very limited and when they're gone they're gone.
================================================== ============

That's fine for a pre-2006 VP2 and IIRC a VP1, but the WMII T/H sensor
assembly is a different item again I'm afraid. TBH I've never really looked
in detail, but it may be that the actual 2-pin humidity sensor element from
a VP1 board might fit in a WMII assembly. But even if that's the case
there's no guarantee that it will restore correct readings.

On a WMII, there's no obvious reason why the OAT shouldn't continue to work
OK even if the RH is faulty. But I'm guessing that the WMII is now some
12-15 years old and there comes a point where station renewal is the only
real option.

I solved the
problem by replacing the temp/RH sensor with one of the new 'enhanced'
sensors which are supposedly more accurate. It has all been working fine
since then.

If anyone wants more detail on the digital T/H sensors in the Davis VP2 and
Vue stations then a detailed description is included in the following topic
on the Davis knowledgebase that we maintain:

NB1 This isn't really intended as light reading but the details are there if
you need them!


That's an interesting article, John. I hadn't realised it was all so
complicated. I recently bought the 7346.174 version to replace my faulty one.
I'm very happy with the replacement. Fitting it was no great problem though it
is useful to have a second person to hold the 'pile of plates' when the
temperature screen is dismantled. I also took the opportunity to give the whole
thing a good clean.

It's probably packed up. If it has, I'm afraid that spares are no longer
available, as I discovered when mine suffered a similar fate.

The temperature sensor will continue to work and, from memory, it's
relatively easy to modify the software to eliminate the humidity
readings and displays - I think.

It's on it's way out, but overnight it dropped to 95% but now back to
100% and looking the radar will stay 100% until the morning...

Humidity here has been = 98% for the last 5 days. Maybe it's right? Check
around nearby stations.

It's not stuck it's jsut acting dawlish for the duration of the spell. there is a twin cored High in the middle of the North Atlantic so it is only fair that you feel a little miffed.

Just take note of what happens next and realise that your machine was trying to tell you something:

"Look Keith, I can see you're really upset about this. I honestly think you ought to sit down calmly, take a stress pill, and think things over." or "I am putting myself to the fullest possible use, which is all I think that any conscious entity can ever hope to do."
