Falcon wireless 3-axis sensor is my sons favorite.
FYI the top membrane keyboard that does not survive a wet end in a papermachine is €90:- as a spare part, don't accept the "it is not in the sparepart list"... Part number is MEK1122 WLS TOP with lexan. You only need some fine finger skills and a angled pliers since it is a flexi film connector only. You void warranty etc but that was anyway long gone. You can see in the picture what we used until we got the spare part...... The charge to repair it is near the same as a new sensor and that is substantial......

Hi OLi,

Why does it not survive a wet end..? Some serious lack of market research.  or their engineers are afraid of wet ends preferring to site in offices.... Pulp & Paper is such a great testing ground. I have seen so many cheap accelerometers fail.  heat, wet, humid and compared to sitting in an office you have to be very careful on the slippery steps and ladders. The latter are obviously more of a personal safety concern.

It is WiFi device w/o cable so the HMI is a standard membrane keyboard w/o any sealing. There are 2 LED and 1 click button and water get in btw. the sticker on top of the keyboard and the PCB that is the keyboard and eventually it is destroyed. I told them 3-4 years ago when we broke the first, we are now into our 3rd. The latest we tried to seal the keyboard edges with superglue and adhesive and it prolonged the suffering maybe a year. So we started to work to "repair" the oldest with result as picture above. It works as a spare until we get the new "lexan" keyboard.
No they don't see paper as a market for them but it is wet in a refinery also and keyboards are expendable items.
They seem to have a fixed repair cost and spending 80% of a new sensor on 5min open swap keyboard and close is not acceptable so first time it was replaced as the first was a prototype and the 2nd I bought a new sensor as the difference in cost was not enough so now I try to repair them one way or another.

So when you say keyboard Olov you mean the entire analyzer screen doesn't hold up well in wet environments? or is it just the wireless sensor? I was seriously considering this system a few years back, I work in a lot of wet and shitty quarry also wet dairy plant environments. This is good to know.

It is the primarily the sensor button. I will report if we get a new version but those we saw at a refinery last week was the same and they were just delivered. Screen on the box is a different story, it is a touch screen and it is delivered with a second layer protective plastic with a frame around that is useless as water enter btw. plastic and screen directly so that goes off first day but then the displayed survived quite a few years now. You need to wipe it from time to time but otherwise it is good, I think I swapped battery once but that is no major problem if you are fiddly enough.
