An update:
Kavlico sensor, Dynon-Display
https://cloudstorage.uni-oldenburg.de/s/9SnWCPDjxSSuCDr with fluctuations
Kavlico sensor, analog instrument
https://cloudstorage.uni-oldenburg.de/s/yK1wZiaqBsZh8op no fluctuations
This appears to me to point to the Dynon EMS.
What we checked:
Rotax sensor, at the engine, voltage Pin 6-Ground: no fluctuations
Rotax sensor, external air pressure, heated to 70°, Voltage Pin6-ground: no fluctuations
Rotax sensor, external air pressure, heated to 70°, Voltage Pin6-external 12V: no fluctuations
Kavlico sensor, external air pressure, heated to 70°, Voltage Pin6-ground: no fluctuations
Kavlico sensor, external air pressure, heated to 70°, Voltage Pin6-external 12V: no fluctuations
VDO sensor, at the engine, analog instrument: no fluctuations
VDO sensor, at the engine, Dynon: values off (it's a 0-5bar type instead of the required 0-10 bar), little fluctuations
Rotax-sensor, at the engine, setup for kavlico: values off, little fluctuations
Bluetooth sensor, at the engine, mobile phone display: no fluctuations
Fluctuations only appear when values are displayed at the Dynon. Fluctuations appear to be less when the displayed values are in the upper 20% of the range. Maybe someone from Dynon may relate this to the internal measurement setup/schematics of pin 6 input.
The Dynon just came back from firmware update and Horizon calibration.
