Fitted with the converter Connexx®, the load cell PR 6211 offers a whole host of possibilities:
- The digital version guarantees fast signalling times for reliable dosing processes.
- Thanks to the use of field bus communication, the cable junction box is no longer needed.
- The standard interface CANopen ensures straightforward installation and calibration.
- CANopen allows for extra-long communication paths of up to 200 m.
- Weight values can also be generated individ- ually – per load cell – meaning that defective load cells can be identified more easily.
