The airflow monitor is used to monitor ventilation, heating, and air conditioning systems, as well as for monitoring in switchgear. The sensor, connected to the measuring relay via a cable, detects the airflow and compares it to the set target value. The target value is set on the front side using a screwdriver. There is an indicator for relay output and operating voltage. The probe comes with a 2.5 m cable, extendable up to 10 m.
