Description

The model A2G-FM measuring probe measures air velocities and air flows in ventilation and air-conditioning systems. The intelligent design makes for a very easy installation in existing ventilation pipes and ducts.

Based on the pitot tube principle, the probe measures the total pressure (Ptotal) and the static pressure (Pstatic) of the air flow. The probe determines the average air velocity, measured via 6, 8 or 10 exactly positioned sensor openings, depending on the diameter of the ventilation pipes or the length of the ventilation ducts.

The unique shape of the probe enables measurement even at very low air velocities of down to 1.0 m/s. Bevelled inlets to the measuring probe openings provide for a high measurement accuracy, even under unfavourable flow conditions.

In combination with the model A2G-25 air flow meter, this offers the user a very accurate and cost-effective air flow measuring equipment.

In conjunction with the model A2G-100 PID controller, a highly efficient and very easily adjusted air flow control for ventilation and air-conditioning systems can be provided.

The measuring probe is available in two different versions, depending on the requirements and the installation situation.
