FM41 Axial Fan Demonstration Unit

 

FM41 Axial Fan Demonstration Unit

The Armfield 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.

Description

The Armfield 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 Armfield 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.

Features & Benefits

Downloads

  • Measurement of inherent-speed machine performance in terms of static and total pressures, rotor speed and motor input power as a function of inlet flow

Armfield IFD7

The ArmSOFT software enables the operator to control the fan speed 0 to 100%. Feedback from the sensors is then displayed in real time for the end user with simultaneous data logging.

The data trend is also displayed graphically in real time and can be exported to another platform such as Excel for further analysis.
