Figure 13: Example of good sensor embodiment and housing
Figure 14: Example of good sensor embodiment and housing with airflow channel
Figure 14: "Example of good sensor embodiment and housing with airflow channel"
describes a good design, related to the more efficient implementation with two vent
apertures to get a better connection with the external environment under test that results in
a higher efficiency in terms of response time and an extremely small dead volume. In this
example the vent apertures size is an order magnitude lower than the sensor dimension,
for example an aperture of 0.5 mm provides a good response time and an excellent level of
integration for PD application.
In Figure 15: "Example of a bad sensor embodiment and housing" a wrong design is
described, with a very low efficiency of the final design, in terms of response time and the
sensor under the effects of heating coming from other devices.
