LOAD CELL - INSTRUMENTS

                  DIN RAIL MOUNT-CE APPROVED-PC SYSTEMS 

High quality load excitation module. 

The Digital Amplifier, DAD141.1 is an all-in-one device for non-automatic and automatic weighing, filling or loss-in-weigh operations. The standard device includes all the communication facilities needed for industrial weighing, control and registration, i.e. analog current- and voltage output, Ethernet, RS485 and logic I/O’s for direct control of valves or bars and simple remote operations.

The DAD141.1 is a stand-alone device for DIN-rail mounting (TS35).An App for Android enables set-up and calibration of the DAD141.1 via most smart phones and tablets.

To grant the quality and allow legal weighing the DAD141.1 is OIML R-76 approved and tested to meet the MID requirements to EMC at industrial surroundings.
