iC-PMX    Energy Harvesting Multiturn Counter/Encoder - (new)

Applications
  • Multiturn encoders
  • Absolute end-of-shaft encoders
  • Absolute hollow shaft encoders
  • Absolute linear encoders
  • Period counters
  • Gas meters
  • Liquid flow meters
  • Encapsulated flow meters
Features
  • Gearless and batteryless revolution counter
  • Energy harvesting through Wiegand pulsesą
  • Integrated Hall switch for direction detection
  • Evaluation of Pt1000 sensor output for high accuracy gas meter applications
  • SPI interface to external nonvolatile RAM
  • Independent SPI interface to microcontroller (configuration and data exchange)
  • 4 low-noise Hall sensors with differential analog output
  • Electrical Wiegand wire excitation for synchronization with singleturn
  • Runt pulse tolerant counting algorithm
  • All accessory components are off-the-shelf products


    ąDevices and processes for energy harvesting by Wiegand wire within position encoders are protected by several worldwide patents (such as WO 2004/046735 A1) and require licensing by the inventors and applicants.
