LVDT / RVDT Measurement Boards

For Multifunction Embedded Boards, the LVDT Module provides four measurement channels, programmable with 2, 3 and 4 wire capability. Typically the primary is excited by an AC source, causing a magnetic flux to be generated within the transducer. Voltages are induced in the two secondaries, with the magnitude varying with the position of the core. Usually, the secondaries are connected in series opposition, causing a net output voltage of zero when the core is at the electrical center. When the core is displaced in either direction from center the voltage increases linearly either in phase or out of phase with the excitation depending on the direction.

Two common Methods of Interfacing LVDT to Converter:
• Primary as reference (Two-wire system) - This method of connection converts the widest range of LVDT sensors and is the most sensitive to excitation voltage variations, temperature and phase shift effects.
• Derived reference (Three/four-wire LVDT) - The LVDT is again excited from the primary side, but the converter reference is the sum of A + B that has constant amplitude for changing core displacement. This system is insensitive to temperature effects, phase shifts and oscillator instability and solves the identity (A-B) / (A+B)
