Pneumatic proximity sensors 8.8 Exercises Exercise 8.1 Range of air barrier sensors Parts of a width of 90 mm are to be detected in an area subject to explosion hazard. Check whether on the basis of the characteristics of air barrier sensors of type Festo SFL listed in chapter 8.6, these can be used in this instance. Specify the value of the output signal in kPa (mbar). Exercise 8.2 Checking lids by means of a reflex sensor A reflex sensor is to be used to check that lids have been fitted. Specify a practicable value for the distance between the sensor and the lid. The respective characteristic curves can be found in chapter 8.6. Also determine the air consumption for this configuration in accordance with the characteristic curves in chapter 8.6.
