Transformer VT-4B rotating (VT4B, VT 4B)
Rotary transformers BT-4B are intended for use in electro-mechanical computing devices, servo systems, as well as the primary sensor to digital converters.
Depending on the scheme and the inclusion mode (function) devices rotating transformer VT-4B are divided into sine-cosine (Synchro), output voltage which is proportional to the sine (cosine) the angle of rotation of the rotor, the linear (LVT), the output voltage which varies linearly proportional to the angle of ± 60 ° and large-scale (MW).
