GENERAL INTRODUCTION TO POSITIONING OF GAS DETECTORS

Has to be especially considered for combustible gas detection systems based on catalytic sensors where flow velocities of > 6 m/s can lead to false alarms. These false alarm problems can be eliminated by fitting the sensor with wind calming plates or protective covers which however will lead to increased response times !! 4. Flow direction Has to be considered to position detector such that chance to pick …
