LDU 68.1 - Economy - R76 Approved


Load cell Digitizing Unit 068.101.5. Ver. 2.20


      

LDU 68.1 provides digital data from weighing operations based on strain gauge load cells at a speed and precision suitable for most purposes. Logic operations can be controlled directly vie the dual logic inputs and outputs.
The LDU’s are designed to be embedded into customer’s equipment, to be plugged into a Unit Adaptor or integrated with a hosting device.








Product highlights

  • 2 inputs, 2 outputs, approved
  • An economic solution for most standard
    weighing application.
  • OIML R76 approved for non-automatic
    weighing. Eases the MID approvals of R51,
    R61 and R107 applications.
  • Internal precision reference 2.000.0mV/V
    for mV/V calibration.
  • Supports any automatic or manual
    weighing device with normal requirements
    as to speed and precision.
  • Communicates via a RS 422/485 full
    duplex interface in 32 node networks or point
    to point.
  • Offers dual logic outputs and dual logic
    inputs for various control, filling and sorting
    operations.
  • A graphic presentation, analysis and set
    up PC program, DOP is available.




Product qualities

±131000 counts input signal resolution, 100 nV/count, 90 A/D conversions/sec.
Digital filter performance 60 db/decade LP filter 5 to 0,02Hz.
Can drive 250 ohm load cells, e.g. 4 pc, each 1000 ohm, at 5 Vdc.
Dual logic inputs for position sensors or valve feed back etc. can define a time frame for automatic operations.
Dual logic outputs provide external control of actuators etc., or for internal computing.
Signal conditioning, zero and tare operations convert the load cell output into a calibrated unit (g; kg; lbs; etc.).
To be designed into customers’ PCB or bolted on the side a load cell.
Fits with a selection of Unit Adaptors, offering many I/O facilities and mounting options.

The LDU 68.1 is pin and protocol compatible with other members of the LDU family, (68.2/68.3/69.1/78.1), thus offering a selection of precision levels, functionality and cost.
