Designed for harsh environments such as gas storage tanks and marine equipment, NewTek’s LVDT linear position sensors are designed to withstand high temperatures as well as shock and vibration. The sensors offer high reliability in position measurement with long life expectancy.
One potential use is LNG (liquified natural gas) cryogenic storage tanks where LVDTs sit between the inner and outer tank performing structural monitoring so operators can detect structural shifts or settling. As the space between tanks is sealed and inaccessible due to insulation while filled with nitrogen at above atmospheric pressure, sensor replacement is very cumbersome and expensive. The sensors withstand temperatures from cryogenic to 500°C..
The sensor can also be used in marine applications. When using LVDTs for subsea choke position monitoring and subsea strain measurements, sensor replacement in these remote locations results in considerable work that requires shutting down operations. Constructed of Inconel and exotic materials, NewTek’s position sensors survive indefinitely in corrosive subsea applications where service life requirements typically are 20 years.
In addition to their material construction, NewTek’s sensors operate without mechanical contact between its core and coil assembly, eliminating friction that can shorten sensor life. With no parts to wear, these linear position sensors possess long mechanical life for applications requiring long service life.
