An LVDT differential transformer displacement sensor
A, the differential transformer displacement sensor principle and application:
SMW method - WYDC type displacement sensor is based on the principle of transformer, dc through a coil and the secondary
Weak electromagnetic coupling coil, and makes the core displacement variation and output signals (voltage or current)
Momentum is precision linear relationship, can be directly convert mechanical variation into standard electric signal supply computer
Data acquisition or PLC for process control.SMW method - WYDC series products are the sensor coil
And electronic circuit mounted on a stainless steel tube, realizes the mechanical and electrical integration, strong resistance to dry
Interference ability.This series of products has a large travel and high precision, good stability, and easy to install and use
Points.Is displacement, distance, elongation, mobile, thickness, vibration, expansion, liquid level, compression, strain
And so on physical quantities of powerful tool for detection and analysis. It will sensor, filter, oscillator, and modem
Live, as long as the work outside for dc regulated power supply, besides general ac displacement sensor
Of the features, more show its superiority in the following situations.
Widely used in aerospace, aviation, electric power, petrochemical, machinery, military industry, textile, automobile,
Coal, earthquake monitoring, institutions of higher learning and scientific research institutes and other fields, namely can and instrument,
Can also be used alone.
