An overview of LVIT linear position sensor technology and its applications.
Introduction to LVITs Video Script
The word LVIT is an acronym for Linear Variable Inductance Transducer. The simplest way to describe it, is that it is an electronic ruler. An LVIT gives an electrical output signal that tells a computer or a digital readout the position of an object that it is mechanically connected to.
LVITs have an excellent price-performance ratio compared to other linear position sensor technologies because they are frictionless and don’t wear out. They are simple to mount and have an outstanding stroke-to-length ratio.
An LVIT uses a high resolution inductive sensing coil element coupled to built-in smart electronics. A conductive tube referred to as a Spoiler travels over the coil element changing the inductance. The smart electronics then generate an analog or digital output signal that is proportional to the change in stroke. We can provide custom analog or digital outputs for OEM requirements as well.
LVITs can be used in almost all industrial or commercial environments. Power plants utilize LVITs for monitoring valve position. They are used in automated assembly machines for gauging part tolerances. LVIT sensors can be found in agricultural vehicles for steering position feedback.
LVITs are rugged, sustaining high levels of shock and vibration. They are exceptionally good at operating in harsh environments such as automotive suspension testing applications.
A lot of craftsmanship goes into making LVIT position sensors. These sensors have precision coils that require special winding equipment and years of engineering experience in coil design and application knowhow. Along with that, detailed assembly techniques require years of experience necessary to build quality products day in and day out.
A significant amount of investment must also be made into the test equipment required for temperature compensation and calibration.
