　　8237-1246 WOODWARD overspeed safety device

　　Function:The 8237-1246 overspeed safety device is a safety device used to prevent equipment from speeding.

　　Usage:Widely used in industries such as power generation,petroleum,chemical,metallurgy,and papermaking.

　　Features:

　　High measurement accuracy and fast response speed

　　Multiple overspeed alarm points can be set

　　Has multiple protection functions,such as overspeed alarm,overspeed parking,etc

　　Compatible with multiple control systems

　　Product Description:

　　The 8237-1246 overspeed safety device uses high-precision sensors to measure the speed of the equipment and compares it with the set overspeed alarm point.When the speed exceeds the set alarm point,the device will emit an alarm signal and can take corresponding protective measures,such as overspeed parking.

　　ProTech-GII is an overspeed safety device designed to safely shut down steam,gas,and hydraulic turbines of various sizes when an overspeed or over acceleration event is detected.

　　8237-1246 is part of the Woodward ProTech-GII series.It is an overspeed detection system that can be configured for various types of turbines.If it senses excessive acceleration of water turbines,steam turbines,and gas turbines,it can safely shut them down.In addition to acceleration detection,there is also MPU detection.The 8237-1246 model is also resistant to sulfur,H2S,and SO2 gases.It adopts a triple modular design,which can easily replace a component according to the running product.

　　The additional specifications of this security detection module include:

　　Three independent non voting trip relay outputs.

　　4-20 mA speed reading.

　　Low voltage and high voltage power input.

　　Two out of three people voted in favor of the structure.

　　Models 8237-1246 can also be configured to perform routine tests.This will test each individual module.Its storage temperature should be-4 to 158 degrees Fahrenheit,and it can operate at temperatures between-4 to 140 degrees Fahrenheit.It has a 4.2-inch keyboard display screen.Models 8237-1246 weigh less than 27 pounds and can be installed in standard cabinets.
