LDU 68.2 - Economy - Saving

Load cell Digitizing Unit


LDU 68.2 provides digital data from weighing operations based on strain gauge load cells. It is pin and protocol compatible with other members of the LDU family, (68.1/68.3/69.1/78.1), thus offering a selection of precision levels, functionality and cost.
All LDU’s are designed to be embedded into customers’ equipment, to be plugged into a Unit Adaptor or integrated with a hosting device.

Product highlights

  • 2 inputs, not approved
  • An economic solution for most standard,
    weighing applications.
  • Eases the design of any digital device
    dealing with a load cell input.
  • Supports any automatic or manual weighing
    device with standard 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 inputs for framing etc.
  • A graphic presentation, analysis and set up
    PC program, DOP is available.

Product qualities

±17 bit (±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.
Signal conditioning, zero and tare operations convert the load cell output into calibrated units (g; kg; lbs; etc.) as requested.
EMC compliance and surge protection are provided by shielding and T-filters at all pins.
The secured inputs and protected power input withstand excessive actions. Power supply range is 12-24 Vdc.
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.
