LVDT displacement sensor

LVDT displacement sensor

LVDT linear differential transformer displacement sensor is mainly applicable to the measurement of the stroke and valve opening of the hydraulic servo motor of the main throttle valve of the steam turbine, and the stroke of the hydraulic servo motor of the high-pressure cylinder, medium pressure cylinder and low-pressure cylinder. The shell is stainless steel, with good static linearity, simple structure, reliable operation, wide frequency band, high sensitivity and small time constant.

The product is used to measure various physical quantities such as displacement, distance, elongation, movement, thickness, expansion, liquid level, strain, compression, weight and so on. It is widely used in aerospace, aviation, electric power, petrochemical industry, machinery, textile, automobile, coal, earthquake monitoring, universities and scientific research institutes, which can be used with instruments or alone.
