4027A Series, Precision Power Sensors

RF Power Sensors for Precision Laboratory Applications

1% Accurate Precision Directional Power Sensors


Bird’s® 4027A Series Precision Power Sensors were designed to bring superb accuracy and ease of use together for the engineer in the laboratory. At the calibrated frequency and power level, these sensors are capable of 1% accuracy. With calibration traceable to the National Institute of Standards and Technology, you can be confident of the measurements these sensors provide.

Connectors are required to be equipped on BOTH the INPUT and OUTPUT side of the sensor. Bird guarantees the 4027 Series Sensors at +-1% Accuracy only with connectors the sensor is calibrated and sold with from our factory.
