The LVDT has low power consumption. The coil assembly is typically mounted to a stationary form, while the core is secured to the object whose position is being measured. LVDS system features, such as serializing data, encoding the clock, and low skew, all work together for higher performance. When the core is in the null position, the output voltages of the secondary winding S 1 and S 2 are equal and opposite. MEAS . Unlike LVDT, the input of this transducer is differential value of rotary variable i.e. The number of turns in both the secondary windings are equal, but they are opposite to each other, i.e., if the left secondary windings is in the clockwise direction, the right secondary windings will be in the anti-clockwise direction, hence the net output voltages will be the difference in voltages between the two secondary coil. (a) What is the principle of operation of LVDT? LVDS operates at low power and can run at very high speeds using inexpensive twisted-pair copper cables. As the primary is connected to an AC source so alternating current and voltages are produced in the secondary of the LVDT.
