Product Description

The 8237-1600 is a high-integrity overspeed protection system from the ProTech-G series developed by Woodward, Inc.. It provides critical safety protection for steam, gas, and hydro turbines by continuously monitoring rotational speed through high-precision Magnetic Pickup (MPU) inputs.

Using triple-modular redundant (TMR) safety architecture, the system can detect abnormal acceleration trends and initiate emergency shutdown actions before overspeed conditions become dangerous. This helps prevent rotor damage, mechanical burst failure, and downstream process hazards.

The unit is designed for harsh industrial environments, featuring corrosion-resistant components, sulfur-resistant coatings, and IP56 / NEMA 4X-equivalent enclosure protection for operation in chemically aggressive atmospheres.

FAQ

Does it support hot swapping?
Yes. The TMR architecture allows one module to be serviced while the remaining modules maintain full protection logic.

Can it replace mechanical trip bolts?
Yes. The electronic protection logic provides faster and more precise overspeed detection than mechanical systems.

What speed sensors are compatible?
Standard passive Magnetic Pickup (MPU) sensors mounted on turbine gear teeth are supported.
