Angular measuring LVDT sensor T7-LVDT Cemb Việt Nam

T7-LVDT

Angular measuring LVDT sensor

Transducer T7-LVDT is used for measuring the OPENING POSITION of steam VALVES in a turbine.

The measurement is performed by keying the transducer shaft integrally with the valve opening control device in order to measure the rotation of such device.

Principle of operation

Transformer T7-LVDT/120 allows transforming the rotational movement of the device,

into an electric signal that can be process by a CEMB instrument “T series”
