Claims11
A method for coating a sensor unit comprising:
- providing a sensor element, a sensor body supporting the sensor element, and an output cable,
- applying a first coating by positioning, in an assembled state of the sensor unit, a first layer of a coating on the exterior surface of the sensor unit such as to coat the sensor element, the sensor body, and the output cable, the first layer of the coating having a thickness of between 30 μm and 110 μm,
- after applying the first coating, performing a first curing by curing the first layer of the coating at room temperature for two hours,
- after performing the first curing, applying a second coating by positioning, in the assembled state of the sensor unit, a second layer of the coating on the exterior surface of the sensor unit such as to coat the sensor element, the sensor body, and the output cable, and
- after applying the second coating, performing a second curing of the second layer of the coating at a temperature higher than room temperature for more than twenty-four hours.
