Cost-effective, precise VDT conditioning for SLSC

The SLSC VDT/Resolver Simulation Module offers eight channels of variable differential transformer (VDT) sensor simulation at an unmatched price point. Its highly-flexible nature allows each channel to be configured independently for simulation of a linear variable differential transformer (LVDT), a rotary variable differential transformer (RVDT), or a resolver. Versatile, separate E1 and E2 returns allow each channel to be connected in a 4-, 5- or 6-wire configuration. The included SLSC driver also allows each channel to simulate two 4-wire sensors where shared excitation is acceptable.

The product is only available as part of a complete SLSC system. Contact Bloomy for more information.

SLSC VDT/Resolver Simulation Module features include:

  • 8 channels of LVDT, RVDT, or resolver simulation
  • 4-, 5- and 6-wire configurations, configurable on a per-channel basis
  • Complete transformer isolation
  • Automatic calibration of signal¬†conditioning path using SLSC calibration resources as references
  • Independent control of E1 and E2 returns; simulates nominal and faulty sensors
  • On-board open-circuit fault injection capability
  • Optional low-frequency (400Hz) configuration
  • Custom configurations available upon request
