Multi-Channel Telemetry System | AT-7000

The AT-7000 induction powered Multi-Channel Telemetry System is a high bandwidth, 12 or 16 bit resolution system, for multiple sensor inputs (2 to 256) and is customized to meet the needs of specific applications. The AT7000 systems, in general, acquire signals from a unique mix of sensors mounted on rotor components. These sensors are often strain gages and thermocouples, but the AT7000 can be adapted to a wide range of other sensors as well. The system continuously digitizes these sensor signals and transmits them off the rotor using wireless digital telemetry technology.

Applications 
General purpose rotating shaft sensor applications where multiple channels are needed:

  • Motor temperature monitoring 
  • Field voltage and currents on brushless designs 
  • Multi-channel strain measurement

  • ICP/IEPE accelerometer measurement 
  • Ground fault leakage current 
  • Torsional vibration
Highlights
  • Dependable wireless replacement for slip rings 
  • Sensor data is measure and digitized on the rotor 
  • Modular construction allows for a variety of sensors to be monitored 
  • Rugged construction for high G force applications 
  • EMI resistant digital data 
  • Adaptable to RTD, thermocouple, strain gage, accelerometer, pressure sensor, and voltage inputs
  • Induction powered (no batteries) for continuous use

  • Custom solutions for specific combinations of sensors 
  • Robust split clamp collar, with standardized transmitter modules (other designs available) 
  • High accuracy and data integrity, with 12 bit digital resolution and anti-alias filtering on the rotor 
  • Wide selection of gains and bandwidths 
  • On the fly shunt calibration 
  • Analog and digital system data outputs
