GF1 thermal dispersion fan inlet sensors are designed to be mounted directly in the inlet bell of centrifugal fans or upstream of the propeller in vane axial fans. The streamline design of the sensor does not adversely affect fan performance like other, more cumbersome inlet sensors.

GF1 sensor probes use two “bead-in-glass” thermistors to determine the airflow rate and temperature at each sensing location. Accuracy is percent of reading (not percent of full scale). Performance is assured throughout the entire calibrated range. Probes are connected to a GTx116 transmitter that sums individual airflow and temperatures prior to averaging and outputs to your host control system.

GF1 probes are ideal for fan tracking applications, especially when duct configuration limits the use of -P duct and plenum probes.
