1. A kind of liquid level, parameter detecting sensor, it is by flexible coding band, Photoelectric Detection head, microprocessor and transducer are formed, flexible coding band is to be made by the flexible metal band, liquid level information is pressed the Gray code establishment on flexible belt, some code channels by printing opacity and non-printing opacity are formed, the light hole of high-order code channel is made up of the experimental process light hole, be to connect between the sub-light hole by reinforcement, it is characterized in that:

  • reinforcement is shaped as wedge shape, both sides and surface level acutangulate α

    , and high-order code channel length 1 is experimental process light hole length l oWith several reinforcement width △

    l sum.
