WOODWARD DPG-2201-002 Pressure Gauge Controller

Woodward DPG-2201-002 Pressure Gauge Controller (Digital Governor / Engine Speed Controller)

 

 

 

The Woodward DPG-2201-002 is not just a pressure gauge controller. It is a digital programmable speed controller (governor controller) used in diesel/gas engine and generator set control systems.

It regulates engine speed and load control by processing speed feedback signals and controlling an actuator or fuel system.

Key Specifications

What it actually does

This device is the “brain” of engine speed control:

1. Reads speed signal from MPU sensor (e.g. Woodward 1680-631)
2. Compares actual speed vs setpoint
3. Adjusts fuel actuator signal
4. Keeps engine stable under load changes

So it is used in closed-loop control systems.

Features & Advantages

• High-precision engine speed control (±0.25% class regulation)
• Supports isochronous and droop modes
• PID parameter tuning (P / I / D adjustable)
