D-CAN Canbus Digital Strain Gauge to Data Converter

Features :

  • Simple mounting using M2 screw
  • Connections via plated through holes
  • Low profile to fit in very small apertures
  • Baud rates to 230k
  • High speed to 500 Readings/Sec
  • ±15KV ESD protected
  • Real mV/V calibration
  • Noise Immunity 5x heavy industrial level
  • Diagnostics LED
  • Remote shunt calibration
  • Very high stability
  • Peak and trough recording
  • Programmable dynamic filter
  • Operating voltage (5.4 - 18Vdc)

The D-CAN is a high performance digital signal conditioner for the precision measurement of strain gauge based transducers., providing a CANBus output.

There are two product types available in the range; the DSC and DCELL. Both products offer a  high speed CAN output.
The DCELL PCB is designed to fit inside the majority of sensors, providing a 'digital' load cell with the benefit of very high stability and an RS485 output.

Including the D-CAN into load cell based product enables the building of very high accuracy load cells, using the built in linearization and temperature compensation facilities

For applications where it is not possible to fit the DCELL within the transducer, there is an in line housing available (Model ILE).
