8200-226

The 8200-226 is one of a variety of Woodward505 digital governors that can be used to control steam turbines. Its operator control panel acts as a graphical interface and keyboard, allowing adjustments to be made to and communication with the turbine. In addition, it has a variety of available features, such as automatic start sequence, temperature input options, critical speed avoidance, etc. In addition, there are dual speed and load dynamics, peak speed indication of overspeed tripping, and three normal operation modes, including configuration, operation and calibration modes. The unit includes two redundant speed inputs that accept magnetic pickups, eddy current probes, or proximity probes, plus 20 contact inputs and two 4-20mA control outputs and eight C-relay contact outputs.
Digital governor is a device used to adjust the speed of mechanical equipment.
Digital control governor is a kind of governor using digital control technology. It has the advantages of high precision, high reliability, easy to use and simple maintenance. Digital control governor is a speed as the parameter of the regulator, with the adjustment system, driving mechanism and executive mechanism of three parts. It can be widely used in the speed regulation of various mechanical equipment, such as textile machines, mixers, harvesters, paper machines and so on. The regulation system of the digital control governor is generally composed of a microprocessor or a single chip microcomputer, which can process and calculate the input signal, adjust according to the set value and actual operation, and the drive mechanism and the executive mechanism control the speed of the mechanical equipment according to the instructions of the regulation system.
