Woodward 8272-394
Product Name: Real Power Sensor (4–20 mA Output)
Product Introduction: A three-phase real power transducer designed for accurate measurement of active power (kW) in industrial AC circuits. It converts voltage and current inputs into a linear 4–20 mA DC output signal representing real power flow. This model supports unidirectional power measurement (import or export) and is widely used in generator load sharing and power monitoring systems.
