The displacement sensor 7000TDGN-15-01 is a high-precision linear displacement monitoring device based on the principle of differential inductance (linear variable differential transformer LVDT). Its core function is to accurately convert mechanical linear displacement into standard electrical signals, realizing automatic monitoring, closed-loop control, and fault warning of displacement. It is the core "sensing element" of key equipment in industries such as thermal power, metallurgy, and machinery, especially suitable for harsh working conditions such as high temperature, strong vibration, and strong electromagnetic interference in power plants. It is widely used in TSI safety monitoring of steam turbines, DEH speed control systems, and various industrial automation control scenarios.
This product adopts mature technology of Dynamic Core Differential Transformer (LVDT), which is composed of a primary excitation coil, two sets of symmetrical secondary induction coils, and a movable core. When the iron core undergoes linear displacement with the measured component, the alternating magnetic field of the primary coil induces a differential voltage signal proportional to the displacement in the secondary coil, which is converted into a 4-20mA standard current signal by the signal conditioning unit and directly connected to the DCS/PLC system to achieve real-time acquisition, display, and closed-loop control of displacement. The entire process has no mechanical contact or wear, theoretically eliminating contact resistance drift and mechanical loss, and has inherent advantages of non-contact measurement, zero wear, high linearity, and high resolution.
