Pickering Interfaces launched its model 41-670, a single module that can function as an LVDT, RVDT or resolver simulator. Occupying just one PXI or LXI chassis slot, the programmability of the module means that it minimizes the amount of hardware required. Also, since it sits in a PXI chassis alongside a customer’s other instruments, additional […]

LVDT electronics, Part 2: Interface circuitry
The interface electronics for the LVDT must excite the primary-side winding with a sine wave and then demodulate the two resultant secondary-side waveforms; modern ICs make this analog-signal process fairly straightforward. Part 1 of this FAQ looked at the basics of LVDT excitation, demodulation, and waveforms. This part looks at two standard ICs which implement […]
LVDT electronics, Part 1: Excitation and demodulation
The interface electronics for the LVDT must excite the primary-side winding with a sine wave and then demodulate the two resultant secondary-side waveforms; modern ICs make this analog-signal process fairly straightforward. The first two parts of this LVDT article (see References) looked at the LVDT transducer itself, along with its attributes and history. This second […]
