4028A2M, RF Power Sensor is a high accuracy sensor for use in high power LCD, TFT and Solar processing and other precision high power applications. Intended for use with Bird's 4421A Series and 4421 Precision Laboratory Power Meters. These sensors can provide a threefold improvement in long-term unit-to-unit accuracy.

Connectors are required to be equipped on BOTH the INPUT and OUTPUT side of the sensor.
Bird guarantees the 4028 Series Sensors at 2% Accuracy only with connectors the sensor is calibrated and sold with.
If you do not select connectors when placing this item in the shopping cart someone from sales will contact you to assist with connector selection and final pricing.

Features

• Achieve tighter, more consistent RF power measurements for improved yield.
• ±2% accuracy at specified calibration frequencies and power levels.
• Direct, plug-in operation with the industry standard Bird Model 4421A Series and 4421 RF Power Meters.

Problems/Solutions

• Need very high degree of accuracy - Capable of 2% accuracy
