GE IC3600SOSG1 LVDT Oscillator Card

الوصف

The GE part number IC3600SOSG1 is an LVDT Oscillator Card. This is a specialized electronic circuit board used in industrial control systems, particularly within GE’s legacy Speedtronic Mark I and Mark II turbine control systems. Its primary function is to generate the specific AC signal required to power a Linear Variable Differential Transformer (LVDT) sensor.

Function and Key Features

A Linear Variable Differential Transformer (LVDT) is a sensor that measures linear position or displacement by converting the physical position of a core within a set of coils into a proportional electrical signal. The LVDT cannot function on its own; it requires a precise alternating current (AC) signal, known as an excitation signal, to operate.

• AC Signal Generation: The card’s core purpose is to contain an oscillator circuit that produces a stable, constant-amplitude AC sine wave. This signal is then supplied to the primary coil of the LVDT sensor.
• Signal Integrity: The card ensures the excitation signal is clean and stable, which is critical for the LVDT’s accuracy. It filters out electrical noise and maintains a constant frequency and amplitude.
• System Integration: The card is a vital part of the sensor’s signal chain. The LVDT sensor, powered by this card, generates an output signal whose amplitude and phase correspond to the position of its core. This output is then processed by other cards in the control system to interpret the position.
• Robust Construction: Like other GE industrial control boards, it is built to endure harsh industrial environments, including vibrations, temperature fluctuations, and electromagnetic interference.

Applications

The IC3600SOSG1 is used in any industrial setting that uses LVDT sensors for precise position measurement.

• Power Plants: It is commonly used in turbine control systems to measure the position of control valves, governor valves, and other actuators that regulate steam or fuel flow. This precision is essential for maintaining turbine speed and power output.
• Industrial Automation: It can be used in other industrial machinery where precise linear position measurement is required.
