GE IC3600PTJA4 LVDT TRANSFORMER

الوصف

The GE IC3600PTJA4 is a Linear Variable Differential Transformer (LVDT) Card for the Mark I/II Speedtronic series. It is a specialized interface board designed to process signals from LVDT sensors, which are used to measure position and displacement in turbine systems.

Technical Breakdown 🧠

An LVDT is a sensor that measures linear displacement. It consists of a primary coil and two secondary coils arranged symmetrically around a movable core. When the core moves, it changes the magnetic coupling between the coils, inducing a voltage in the secondary coils proportional to the core’s position.

The IC3600PTJA4 card’s job is to:

• Generate an excitation signal: It sends an AC voltage to the LVDT’s primary coil.
• Read the output signals: It reads the differential voltage from the two secondary coils.
• Condition the signal: It demodulates and filters this signal to produce a clean, linear DC voltage output.

This output voltage is then directly proportional to the position of the movable core, providing the control system with a precise measurement of a component’s position, such as a valve or actuator.

Applications 🏭

The IC3600PTJA4 is a critical component in GE Mark I/II turbine control panels for:

• Valve Position Feedback: Providing a precise measurement of the position of fuel, steam, or hydraulic valves.
• Actuator Control: Ensuring accurate positioning for actuators in the control system.
• System Diagnostics: Providing a continuous, real-time signal of mechanical position for monitoring and safety.
