The magnetic pickup input capability is essential for monitoring the rotational speed of engines, enabling the governor to make real-time adjustments to maintain the desired speed setpoints.

The 8290-184 model is designed for isochronous speed control, which means it maintains a constant speed regardless of load variations. This characteristic is vital in applications where stable engine or turbine speed is critical for optimal performance. Isochronous speed control ensures that the engine operates efficiently and reliably, minimizing speed fluctuations that could lead to operational instability or damage. The precise speed regulation provided by the 8290-184 enhances the overall performance and efficiency of the prime mover, contributing to improved operational reliability and fuel efficiency.

The governor's maximum terminal shaft position for the start fuel limit is set at 95%, ensuring that the engine receives the appropriate amount of fuel during startup conditions. This feature helps prevent over-fueling, which can lead to excessive emissions, inefficient fuel use, or engine damage. By controlling the fuel supply during startup, the 8290-184 promotes safe and efficient engine operation, reducing the risk of operational issues during the critical startup phase.

The 8290-184 is suitable for use with both diesel and gas turbines, demonstrating its versatility across different types of prime movers. This compatibility makes it an ideal choice for various industrial applications, including power generation, marine propulsion, and other sectors where precise speed control of engines and turbines is essential. The ability to function effectively with different prime mover types expands the applicability of the 8290-184, making it a valuable component in a wide range of industrial settings.

This model type is specifically designed to provide speed control capabilities, ensuring that the engine or turbine maintains its desired speed setpoint under varying load conditions. The speed control functionality is crucial for applications where maintaining consistent speed is necessary for process stability, product quality, or system safety. The 8290-184 ensures that speed variations are minimized, contributing to the overall stability and reliability of the control system.

The VDC power supply of the 8290-184 is set at 24 VDC, which is a standard power level in many industrial control systems. This standardization ensures easy integration into existing systems without the need for additional power conversion equipment. The use of a 24 VDC power supply also aligns with common safety standards in industrial environments, providing a reliable and safe power source for the governor's operation.

The 8290-184 comes with comprehensive documentation to support installation, operation, and maintenance.
