AD589-Dual Supply LVDT Signal Conditioner Design Procedure
The Linear Voltage Differential Transformer (LVDT) is a highly precise sensor commonly employed for measuring linear displacement. It operates based on the principle of electromagnetic induction, where a primary coil generates a magnetic field that induces voltages in two secondary coils. The differential voltage between these coils is proportional to the position of a movable core within the transformer, enabling accurate position sensing.
The AD589 integrated circuit is designed to facilitate the signal conditioning necessary for LVDT applications. This precision voltage reference provides a stable output voltage, which is essential for ensuring the accuracy of the LVDT measurements. The AD589 features low noise and low drift characteristics, making it suitable for high-precision applications where environmental factors may influence the sensor's performance.
In a typical LVDT application circuit, the LVDT is connected to the AD589 to amplify the differential output voltage. The output from the AD589 can be further processed using an analog-to-digital converter (ADC) for digital signal processing. This integration allows for the development of sophisticated control systems capable of providing real-time feedback on position changes, which is vital in various automation and robotics applications.
The combination of LVDT technology and the AD589 integrated circuit results in a robust solution for linear position sensing, offering high accuracy, reliability, and stability in diverse industrial environments.LVDT (linear voltage differential transformer) is widely used as linear position sensor.
