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.
