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).
