LDU 69.1 - High Precision - Approved
Load cell Digitizing Unit
Supports any weighing or reference
application, which requires precision
- Offers extreme stability over time and
- OIML R76 approved for non-automatic
weighing to 0.1µV/VSI. Eases the MID
approvals of R51, R61 and R107 applications.
- Internal precision reference 2.000.0mV/V
for mV/V calibration.
- Eases the design of any digital device
dealing with a load cell input.
- Communicates via a RS 422/485 full duplex
interface in 32 node networks or point to point.
- A graphic presentation, analysis and set up
PC program, DOP is available.
±20 bit (±1000000 counts) input signal resolution, 20 nV/count, 172 A/D conversions/sec.
Analog and digital filters offer IIR performance to be set in 6 LP frequency steps up to 3Hz and 60db/dec.
Display output and update performance at 5 updates/second, variable, rolling averaging.
Special pin-out ensures that neighbouring LDU’s synchronize their load cell excitation frequency.
7 points linearization performance.
Broadcast command enables up to 32 LDU’s to read their input in synchronization.
Can drive 250 ohm load cells, e.g. 4 pc, each 1000 ohm, at 5 Vdc.
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 provided by shielding and T-filters at all pins.
The secured I/Os 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.
Certified to meet the EN45.501 requirements.
