Angle detection

Lou_Blue

I have a boat. The engine can be tilted up or down, coving a range of around 260° from fully up to fully down. I would like a more sophisticated sensor that is better than the 5 mercury tilt switches I'm currently using, which works pretty well. This is useful for fuel efficiency and shallow water hazards.

Is there an upgrade available that I can fit in my engine?

  • I can't think of anything of-the-shelf that could directly replace 5 mercury switches in an existing system. It may be possible to use a different type of sensor provided some circuitry was developed to interface it.

    Perhaps a sensor like this:

    However, the range of that is 180 degrees, not 260 degrees. I don't know what accuracy and reliability you need, but a couple of those sensors might work, positioned so that they cover the full range you require. It's no bad thing to use two sensors, because if one fails, then the other can continue working until the failed one is replaced. You might also need some mechanical dampening for long life of the sensors (although the sensor PDF datasheet ( https://www.farnell.com/datasheets/2267166.pdf ) does suggest use with engines, they may require mounting to dampen vibrations (I'm guessing - I know nothing in this area). The datasheet does not mention boat applications (there could be all sorts of environmental issues using it for this application, like corrosion for instance).
