Versatile LVDT/RVDT/resolver simulator module occupies just one PXI slot

29-09-2020 | Pickering | Subs & Systems

Pickering Interfaces has released its model 41-670, a single module that can operate as an LVDT, RVDT or resolver simulator. Populating just one PXI or LXI chassis slot, the programmability of the module means that it minimises the amount of hardware needed. Furthermore, as it sits in a PXI chassis together a customer’s other instruments, further control protocols/interfaces are not required, simplifying operation.


The device can handle up to four channels of 5/6-wire LVDT/RVDT or resolver, or eight channels of 4-wire LVDT/RVDT simulation. Each VDT bank includes an independent excitation input, as well as the capacity to utilise an internally generated excitation signal. It can function with a shared excitation signal to each channel for synchronous test. Several models are offered that support excitation voltages ranging from 0.25VRMS to 38VRMS and frequencies from 300Hz to 20kHz, meaning the family can simulate a broad range of LVDT, RVDT, or Resolvers.


Comments Paul Bovingdon, simulation product manager, Pickering Interfaces: “We believe that the model 41-670 LVDT, RVDT or resolver simulator is more versatile than competing products which are usually limited to just one function. So, we replace multiple products with just one module, which fits in a single PXI slot. We have listened to our customers and delivered a full-featured solution with innovative features that make it easy to use, such as intuitive drivers and a graphical soft front panel for simple manual control.”


The model is aimed at applications including aircraft wing and landing gear control, satellites, motion control for industrial automation, gun/missile launcher targeting, and turbines and nuclear reactors. A PXIe version is offered upon customer request.
