Title：Application of linear displacement sensor in closed loop control system of control valve
Brief introduction：At present, the displacement sensors commonly used in valve spool position detection include potentiometer principle, linear displacement sensor and LVDT displacement sensor. LVDT displacement sensor has high precision and strong anti-interference ability. It is also widely used in control valve system, but it is not suitable for high-speed dynamic measurement due to its large size, high cost and low frequency response. Potentiometer principle linear displacement sensor has high precision, good stability and low cost. It can be designed with small size to meet the requirements of high precision and low cost of co...... [MORE]
