2.3 Sensor protection
An optional filter can be adopted as sensor protection from dust, water, or chemical solvent
by a sensor chamber, in presence of harsh environment or for water proof application. The
key parameter for this kind of implementation is the appropriate choice of the membrane,
according to the design requirements and taking into account that the membrane material
will provide a slower response time, in particular in term of pressure response time. The
sensor integration should protect the sensor from the light as well, therefore inside the
application; the sensor should be housed in a dark place, where the light cannot reach the
sensing element.
