Genauigkeit MSPEED EX

Ja da hängt viel mit ein Einbau zusammen... Ich dachte auch einen Moment dran in die Nase von meinem Segler ein MSPEED zu stecken (die Kupplung baue ich i.d.R. unten weiter hinten ein) ... Aber die Messergebnisse kann man gleich vergessen so mit Unterdruck und so...
Unter idealen Bedingungen ist der Sensor sicher ausreichend genau.

Hi,

I have from a Jeti MSPEED EX sensor mounted on my jet. When flying we noticed that the speed the sensor is giving us on the Jetibox Pro is way off. So I tested it on a test bench that is been used to test real jet fighter planes speed indicators. During testing we noticed that there is a deference of +/- 100 km/h. Setting the bench on a speed of 100km/h results in a speed on the box of +/- 140 km/h. The faster we go the more the difference is.

Anyone still having the same problems?

Yes. Accuracy seems to vary quite a bit from sensor to sensor.
I flew a MSPEED 360 sensor in my speeder plane where I was able to easily hit the 100 m/ sec limit.
So I exchanged the sensor with the new MSPEED 450. The pitot tube and silicon tubes remained the same at exactly the same position as before.
interestingly the max top speed I can achieve now is around 320km/h with exactly the same power train and setup as before. (BTW the 320 are way more realistic than the previously measured 360km/h )
