A Linear Variable Displacement Transducer (LVDT) is a reliable solution that can be used when physical displacement or position needs to be converted into an electrical signal for control or indication purposes. Here at Sentech, our LVDTs facilitate contactless operation, with long life, no loss in performance, infinite resolution, unlimited mechanical life, single-axis sensitivity, damage resistance, fast dynamic response, and absolute output. They perform well in high-pressure situations, with our strong engineering and manufacturing capability that’s designed to last no matter what the demands.
In an ideal situation, the output voltage at the null position would be zero. In reality, you’ll find a small voltage discrepancy. It’s known as residual voltage, as it represents the small amount of voltage at the null position. It can be caused by the presence of harmonics in the supply voltage due to the use of an iron core. Acceptable limits for residual voltage in LVDT are less than 1% of the full-scale output voltage.
The LVDT sensor is designed to support either a single-channel or multiple-channel device.
The formula for the LVDT output voltage is the differential voltage between the two secondary windings. Usually, the output voltage is converted by using suitable electronic circuitry. You can use a high-level current.
