The SFAB uses a thermal measurement method. Here, the amount of heat drawn
from a heated surface of the sensor by the medium flowing past it is calculated.
Through the amount of heat removed, the flow rate or accumulated air consump­
tion is determined and shown on the display. The connection to higher­level sys­
tems is implemented through 2 binary outputs (Out A/OutB) and one analogue
output. Switching points can be defined for both binary outputs. Switching points
for both binary outputs are possible for flow rate measurement, a consumption
switching pulse for output A (OutA) is possible for cumulative air consumption
measurement. The combination of cumulative air consumption measurement
(OutA) and flow rate measurement (OutB) is possible. The flow value is output via
the analogue output.
