Linear Variable Differential Transformer. How LVDTs Work. The LVDT or Linear Variable Differential Transformer is a well established transducer design which has been used throughout many decades for the accurate measurement of displacement and within closed loops for the control of positioning.
Double Pole Double Throw, DPDT. Double Pole Double Throw relays supply two single double through relays, SPDT, in one relay package. This combination provides tremendous design flexibility. Dual circuit functions can be controlled with a single coil signal. Since the contacts are mechanically linked in many applications one of the contact sets are used as auxiliary contacts to provide circuit feedback indicating relay contact position.
