ifm SL5101, Flow Controller, 100 → 1000 cm³/s, Relay Output, 24 V dc, 23 mm Pipe
The SL5101 compact flow monitor from ifm ensures the optimum air flow thanks to easy setting in a range from 100-1,000 cm/s via potentiometer. The immersion depth into the duct can be flexibly varied via the supplied mounting clamp. Titan sensing faces ensure reliable operation, even with aggressive air, at a medium temperature from -10-50 °C. The SL5101 airflow monitor is available in the electrical design 24 V AC/DC with a 2 m PUR/PVC connection cable. Typically the airflow monitor is used for airflow monitoring in ventilation systems and/or suction operations.
