Product catalog summary
Overview
SENSY's digital converters are designed for applications involving the direct connection of load cells to computers or PLCs. They offer digital linearisation and thermal compensation integrated into the transducer, providing high resolution and transmission speed. These converters can be mounted internally or externally, with external models housed in an IP65-rated aluminium box.
Applications
  • Scaling of output signal in measuring units
  • Easy connection to PC or PLC
  • USB-ASC models are self-powered by the port
Features
  • Temperature measurement with compensation for thermal drifts
