Cost-effective, precise VDT conditioning for SLSC
Bloomy's 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 VeriStand SLSC driver also allows each channel to simulate two 4-wire sensors where shared excitation is acceptable.
This module requires the use of a PXIe-6738 high-density analog output or better.
Bloomy's SLSC VDT/Resolver Simulation Module can be used in a range of test system applications including:
- Real-time hardware-in-the-loop (HIL)/closed-loop test systems
- Electronic engine control (EEC) test systems
- Flight control computer (FCC) test systems
- Environmental control test systems
