LVDT position sensors
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.
