Fuel Pressure output difference

    Thank you.

    Throughout the Sensor output values, there is a difference of 0.04 to 0.05VDC between the measured and expected sensor output. Fine for us.

    1. Could you please tell us the Sensor output Accuracy value?
    2. Why am I asking this is, We are unable to find the formal specification/datasheet of this sensor anywhere? Could you please share it. We are looking for the accuracy of the sensor.

    We believe Rotax could make and share the sensor's specification/datasheet.

    If it is fine with you, then what is the issue.
    The sensors are typically quoted as 1%.
    Your readings are consistently about 0.05v too low.
    This would indicate a possible measuring error offset.
    Subtract 0.05v from your measurements and you are ±0.01v(0.25%) across the range.

    Rotax buys the sensors from outside vendors and has them rebranded.
    You're not going to get the spec sheet from Rotax.
    Remember that this is not a dedicated fuel pressure sender, it is just a generic pressure sender.
    Gasoline, Diesel, alcohol, water, Air, etc., it does not care. It just reports pressure.
    If you were to search online for Pressure Senders, you will likely find a look-alike unit with the same specs.
    It will probably be the manufacturer that sources the Rotax part.

    If you are looking for an official response from Rotax, you will need to contact Rotax directly or through one of its distributors. This is Not the Place.
    Official Enquires about Stock Flight Produces will need to be directed to Stock Flight Systems.

    Otherwise, the people here will try to help you out but you will need to filter the information that you receive as none of it is Official in any sense.
