Hi, i have SKF pump with 10l cointainer for oil. In cover is mounted ultrasonic sensor for measuring level of oil. Cointaner has 45cm froom min to max space for oil filing. Ultrasonic sensor has 0-800mm for 0-10V range so it need to use scaling for 45cm distance from minimum to maximum. Minimum is 7 percent ( prevent of emptyng to zero ) Maximum is 100 percent Unfortunately, I found that there is a non-linearity in the measurement range. Do you have any idea how to linearize the curve in this range in the log? Please see attached excell sheet with chart how the sensor send outputs voltage in measurement range. Thank you :-) Marek.

I don't think the sensor doesn't work linearly. Maybe it appeals to you. AttachmentLevel.zip (285 Downloads) |
