| Dec 16, 2016 at 13:44 | comment | added | Oystein | The upper limit's not really relevant, as we're never experiencing pressures that will output those voltages. But in any event, the method you're proposing is much faster to implement and fairly easy to compensate for in a GUI. But how will such a method load the sensor? We're using a Keller 23 SY Ei pressure sensor with 0-5V output, which has a max. 5mA output current. | |
