Bird - 4028 Series Directional Thruline RF Power Sensors High Accuracy for Precision High Power Applications The Bird 4028 Series RF Directional Thruline Power Sensors are designed specifically for use for use in high power LCD, TFT and Solar processing as well as other precision high power applications. Because accuracy is critical, these sensors are capable of ±2% accuracy at the calibrated frequency and power level which can improve accuracy and long-term repeatability for significant improvements on your process yields. Multiple sensor models are available for measurement applications from 1 kW to 25 kW to over a 250 kHz to 30 MHz frequency range. Calibration is traceable to the National Institute of Standards and Technology (NIST), providing additional confidence in sensor measurement.
