4027F Series

Bird 4027F Series Power Sensors are similar to the 4027A series. However,

additional filtering allows the 4027F to ignore harmonics of the signal being

measured. The 4027F is also less sensitive to AM components of the signal.

4027F Sensors are accurate to ±1% at specified calibration frequencies and

power levels.

Load

Bird loads are available in power ranges from 1 – 10 kW. The loads have a

coolant chamber surrounded by radiator fins. The front and rear fins form

mounting flanges which are used as brackets for mounting the load on the Cal

Cart. Vent plug(s) at the top of the load relieve internal pressure from coolant

expansion. For further information, refer to the load manual included.
