Product Profile of Linear Variable Differential Transformer

Linear Variable Differential Transformer or LVDT is offered by the ISO 9001 certified company Forbes Marshall. The Linear Variable Differential Transformer comes in the LS Series. The LS Series Linear Variable Differential Transformer is a highly reliable linear transformer which provides long-range measurement of turbine valve opening and casing expansion. These Linear Variable Differential Transformers have broad range of applications due to its durability and measuring accuracy.
Main functions of Linear Variable Differential Transformer or LVDT are:

• Various measurement ranges: The LS Series LVDT comes in nine measuring ranges from 50 to 450mm.Suitable for long range displacement measurement.

• High accuracy: Linearity is ± [plus-or-minus] 0.2% of full stroke. Suitable for governor control requiring high accuracy.

• Environment: Heavy duty specifications and high reliability. Anti-vibration: 490m/s2

• Operating temperature range: minus 40 to plus 150 degree C [for terminal block type].With built-in magnetic shield to eliminate the effect of external magnetic fields.
Main Applications of Linear Variable Differential Transformer or LVDT: In the governor control of gas and steam turbines, the valve opening is adjusted so that the number of revolutions becomes constant while the load condition and the number of revolutions are monitored. The LS series transducer measures the valve opening and is used for feed back the signal to the electronic governor controller.
