High Temperature, High Accuracy Resolver-to-Digital Converters

Bohemia, New York (June 3, 2015) Data Device Corporation (DDC), introduces a new High Temperature Resolver-to-Digital Converter (RD-1930X), offering an off-the-shelf, high reliability motion feedback solution for today’s rugged, high temperature applications. Resolver-based motion feedback systems offer inherent environmental advantages over optical encoders that are vulnerable to humidity, dirt, oil, grease and vibration. DDC’s RD-1930X resolver-to-digital converter offers additional environmental advantages, by utilizing Silicon-On-Insulator (SOI) technology, to extend the operating temperature to +200°C, for use in extreme thermal environments. The RD-1930X series also provides high accuracy 14-bit resolution, enabling positioning to 8 arc-minutes. The durable design of the RD-1930X, combined with its high accuracy and flexible programmability (resolution, bandwidth and tracking), makes this resolver-to-digital converter ideal for position control applications exposed to extreme thermal environments, including oil and gas downhole drilling, commercial aerospace engine control, missile fin actuation, and factory automation.

Benefits include:

  • Ruggedness
    • -55°C to +200°C Operating Temperature
    • Field Proven, Rugged Ceramic Package
  • Flexibility
    • Programmable Resolution (10, 12, 14 Bit), Bandwidth & Tracking
    • Provides Analog Position Conversion to a Digital Signal for Synchros, Resolvers, Inductosyns, LVDTs, RVDTs, MRs, and Hall Sensors
  • Efficiency
    • Standard Off-the-Shelf High Temperature Solution Enables Faster Time-to-Market
    • Integrated Reference Oscillator Reduces Costs & External Component Count
    • Serial Output (SPI) Utilizes Less I/O from Processor (Parallel Output also Available)

“These high-temp resolver-to-digital converters combine extreme durability, with high accuracy position feedback and off-the-shelf availability, to provide long lasting performance in the harshest environments, while remaining a cost-effective and efficient motion feedback solution” stated Rolf Mahler, Product Line Manager, DDC.”
