FM41 Axial Fan Demonstration Unit Didactic Equipment Vocational Education Equipment Fluid Mechanics Lab Equipment
DESCRIPTION The Axial Fan Demonstration Unit is fitted with electronic sensors to measure the pressure head developed across the fan, the pressure across the orifice plate (and hence the flow rate), the rotational speed of the fan and the air temperature. The fan speed is controlled by modulated dc supply complete with current sensing to enable the power drawn by the fan to be measured. The axial fan demonstration unit is mounted on a stainless steel plinth. Transparent air inlet and air outlet ducts allow the fan construction to be clearly observed. A manually operated adjustable aperture allows the air flow rate to be varied. A calibrated orifice plate is used on the discharge to measure the air flow rate. Electronic sensors measure the pressure head developed across the fan, the pressure across the orifice plate (and thus the flow rate), the rotational speed of the fan and the air temperature. The fan speed is controlled by modulated DC supply complete with current sensing to allow the power drawn by the fan to be measured. TECHNICAL SPECIFICATIONS Max flow rate: 38 l/s typical Max head: 0.06kPa Max fan speed: 2,700rpm Motor power rating: 5W 2 x pressure sensors: 0 to 2.5mBar Inlet Duct Diameter: 123mm Infrared Sensor to measure Fan Speed
