LVDT (Linear Variable Differential Transformer) sensor can directly change the amount of mechanical changes into a standard electrical signal for computer data acquisition or PLC process control. It is a powerful tool to detect and analyze the displacement, distance, elongation, movement, thickness, vibration, expansion, liquid level, compression, strain and other physical quantities. LVDT displacement sensor can be not only used with the instruments, but also used alone.
Applications: LVDT sensors are widely used in aviation, electric power, petrochemical industry, machinery, military, textile, automobile, coal industry, seismologic surveillance, universities, research institutes and other fields.
