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. Fig. 8.8.1: Lid monitoring by means of a reflex sensor © Festo Didactic GmbH & Co. KG • FP 1110 135 136 © Festo Didactic GmbH & Co. KG • FP 1110 9. Selection criteria for proximity sensors In the first instance, proximity sensors can be sele...
