FUNCTIONAL DESCRIPTION:

IC3600QOXB1 is an Over Speed Sensor Card manufactured and designed by General Electric as part of the Mark II Series used in GE Speedtronic turbine control systems. The Over-Speed Sensor Card continuously monitors the rotational speed of the turbine blades using high-precision sensors, such as proximity sensors, tachometers, or hall-effect sensors. It ensures that the turbine remains within its designated speed limits during all operational phases, including startup, operation, and shutdown. Each turbine has an optimal operating speed defined by its design parameters. Exceeding this speed can lead to dangerous vibrations, component fatigue, or even mechanical failure. The Over-Speed Sensor Card is designed to compare the turbine's real-time speed with a pre-set threshold (maximum allowable RPM). If the turbine exceeds this safe threshold, the sensor card acts to prevent damage.

FUNCTIONS:

• The primary function of the over-speed sensor card is to continuously monitor the turbine's rotational speed. Using high-precision sensors such as proximity sensors, tachometers, or Hall-effect sensors, the card measures the turbine's speed in real time. It compares this measured speed to the pre-set maximum safe operating speed, which is determined by the turbine's design and operational limits.

• The over-speed sensor card is configured to compare the actual turbine speed against a pre-set threshold (the maximum allowable speed). The card is set with parameters based on the turbine’s maximum rated speed (often expressed in RPM - revolutions per minute).

• The over-speed sensor card works in tandem with the turbine’s Distributed Control System (DCS) or Supervisory Control and Data Acquisition (SCADA) systems. It sends real-time speed data to these central monitoring systems and receives instructions for shutdown or corrective actions when necessary.

• The sensor card ensures that the turbine operates in compliance with industry safety standards and regulatory requirements. It provides an additional layer of protection by adhering to established protocols like ISO standards or API guidelines, which may be required in certain industries (e.g., oil and gas, power generation).

FREQUENTLY ASKED QUESTIONS:

What is an Over-Speed Sensor Card in turbine control systems?

An Over-Speed Sensor Card is a safety device used in turbine control systems to continuously monitor the rotational speed of a turbine. If the turbine exceeds its safe operating speed (pre-set threshold), the card initiates alarm signals and safety actions such as emergency shutdowns to prevent mechanical damage or catastrophic failure.

How does the Over-Speed Sensor Card detect an over-speed condition?

The sensor card uses high-precision sensors, such as proximity sensors, tachometers, or Hall-effect sensors, to measure the turbine’s rotational speed. It constantly compares the real-time speed with a pre-configured safe speed threshold. When the actual speed exceeds the set limit, the card detects an over-speed condition and triggers alarms and safety actions.

How accurate is an Over-Speed Sensor Card?

The accuracy of an over-speed sensor card depends on the quality of the sensors used. Most modern sensor cards are highly accurate, often within ±0.5% or better, ensuring precise detection of speed changes. Accurate detection is critical for turbine safety.
