The SL5101 AirFlow sensor is a calorimetric sensor that detects air flow above or below a pre-set threshold in a range of 1 to 10m/s. The output is a normally open (NO) relay contact. The sensor needs a 24Vdc power supply and can be used with ARES, Damocles, Poseidon2, SD-2xIN and STE2 environment meters.
