WOODWARD 8440-2082 is a configurable steam turbine digital governor control module. The following is a detailed introduction to it:
1、 Basic Overview
Brand: WOODWARD
Model: 8440-2082
Application: This module is suitable for steam turbine control systems in industries such as power plants, steel mills, cement plants, ships, and papermaking.
2、 Main features
Input saturation free: Adopting the Rogowski principle, it abandons the magnetic core that must be used in traditional transformer or Hall principles, allowing for a large input range without affecting product performance.
Fast response time: The response time can reach the microsecond level, suitable for situations such as fault recording in power systems that require fast response.
Wide frequency response: The bandwidth range can reach over 20kHz, suitable for detecting signals with complex input waveforms.
Good linearity: The output linearity can reach 0.2%, which can accurately reflect the size of the input signal.
High precision: The overall precision of the product is within 1%, ensuring control accuracy.
Small size and light weight: Under the same input range conditions, compared to products based on traditional transformer principles and Hall principles, they are smaller in size and lighter in weight.
