How it Works - LVDT  Data sheet (126kb) |  | ||||||||||||
| These transducers are for displacement / position measurement. They make an accurate position measurement of the movement of the armature (the sliding part) relative to the body of the displacement transducer. This transducer uses the Linear Variable Differential Transformer (LVDT) principle which means that it is probably the most robust and reliable position sensor type available. The strength of the LVDT sensor's principle is that there is no electrical contact across the transducer position sensing element which for the user of the sensor means clean data, infinite resolution and a very long life. The GT series gauging transducer employs precision linear bearings to optimise the LVDTs measurement precision and repeatability. LVDT transducers require external signal conditioning as detailed in the 'Electronics' section of this website. | |||||||||||||
| Spring return version. | ||||||||||
 | Our spring displacement transducer has bearings to guide the armature inside the measurement sensor and a spring which pushes the armature to the fully out position. Spring return LVDTs are appropriate where it is not possible to connect the transducer armature to the moving component being measured. | |||||||||

| Air push version. | |
| The air-push version of the GT displacement transducer is extended by the application of air to the displacement transducer and is retracted by an internal spring. This is useful where the LVDTs position measurement tip must be retracted to allow components to move on a conveyor for example. |
