Woodward Corporation, a leading manufacturer of industrial control and monitoring systems, today announced the introduction of the new ProTech 203 overspeed protection system, Model 9907-147. This system is designed to provide overspeed protection for industrial equipment, especially rotating machinery such as turbines, compressors, etc., to prevent equipment damage due to excessive speed
.

Product features:

High-precision monitoring: The 9907-147 uses magnetic pickups to monitor the overspeed conditions of the equipment’s primer speed, with a speed sensing frequency range of 100 Hz to 32 kHz and an accuracy class of ±(0.05% x Trip Point in Hz +2 Hz).
Triple module redundancy: The system is overspeed detected by three independent speed sensing units, which independently monitor speed and perform calculations, ensuring system reliability with a configuration in which tripping is triggered only when at least two units detect overspeed.
Easy to program: The trip set point can be programmed individually for each unit, and each unit has an operating interface that includes two lines of 16-character LCD display, trackpad, potentiometer, LED indicator, and alarm output.
Secure lock: Programming and test functions are locked to prevent unauthorized changes, and all three units switch between monitor mode and program mode with a single key switch.
