Why LVDT linear position sensors deserve a second look

Why LVDT linear position sensors deserve a second look

The basic operating principle of the LVDT remains unchanged over the years. An electromechanical sensor, the LVDT consists of two basic elements: a stationary coil assembly consisting of a primary coil centred between two identical secondary coils and a movable core or armature. The LVDT produces an electrical output directly proportional to the displacement of its core. AC carrier excitation is applied to a primary coil. Secondary coils, symmetrically spaced from the primary, are connected externally in a series-opposing circuit. Motion of the non-contacting magnetic core varies the mutual inductance of each secondary to the primary, which determines the voltage induced from the primary to each secondary.

High-Pressure and Seawater Resistant LVDT Position Sensors are custom designed for incorporation into sub-sea measurement systems used to monitor structural movement for long-term Finite Element Analysis of offshore platforms, pipelines, derricks, moorings and other critical high-stress members on offshore oil platforms. The High-Pressure and Seawater Resistant LVDT Position Sensors can also be used to measure the position of the valves, called chokes, on sub-sea oil well control towers (called Christmas trees), located at the well-head, as well as controlling or measuring position of robotic arms and actuators. Macro Sensors High-Pressure and Seawater Resistant LVDT Position Sensors resolve the problem of getting a signal back to the surface for monitoring, recording and/ or controlling some physical action taking place on the surface or sea water, even in great water depths. To minimize the number of pressure-sealed connections and I/Os, a 4-20mA two-wire, loop-powered I/O can be utilized, which is then converted to a RS485 signal for transmission to the surface.
