The **LCS-03-R/E2** is a high-precision, industrial-grade linear displacement sensor (commonly referred to as an LVDT or inductive transducer). These devices are used to convert mechanical motion into a proportional electrical signal. --- ## 1. Core Technical Specifications The electronics of the LCS series are designed for durability and high repeatability in automated environments. | Feature | Specification | | :--- | :--- | | **Type** | Linear Displacement Sensor (LVDT Type) | | **Measuring Range** | ±1.5 mm (Total 3 mm stroke) | | **Sensitivity** | Approx. 0.3 V/mm (varies by excitation) | | **Excitation Frequency** | 1 kHz to 10 kHz (standard 5 kHz) | | **Linearity** | < ±0.5% of Full Scale | | **Connector Type** | E2 (Standard Industrial Plug/Socket) | --- ## 2. Internal Electronic Components The device operates on electromagnetic induction principles rather than resistive contact (like a potentiometer). This ensures a long electronic life since there are no parts to wear out. ### A. Primary and Secondary Coils * **Primary Coil:** Receives an AC excitation voltage (the input). * **Secondary Coils:** Two identical coils wound in opposition. As the internal core moves, the magnetic flux coupling changes, creating a differential voltage. ### B. The Ferrite Core * The moving part inside the sensor is a high-permeability nickel-iron core. Its position determines the balance of the magnetic field between the secondary coils. ### C. Connection Interface (E2) * The **E2** designation refers to the specific wiring and connector termination. * It typically features a high-shielding cable to prevent EMI (Electromagnetic Interference) from affecting the low-voltage AC signal. --- ## 3. Signal Conditioning Requirements Because the LCS-03-R/E2 is a "passive" inductive sensor, it requires external electronics (a signal conditioner or amplifier) to function: 1. **Oscillator:** Provides the stable AC sine wave to drive the primary coil. 2. **Demodulator:** Converts the AC output from the secondary coils into a DC voltage (e.g., 0-10V) or current (4-20mA). 3. **Filter:** Removes high-frequency noise and the carrier frequency from the final output signal. --- ## 4. Typical Applications * **Quality Control:** Measuring the thickness of precision machined parts. * **Automation:** Feedback for hydraulic or pneumatic cylinder positioning. * **Structural Testing:** Monitoring minute shifts in bridges or building foundations.
