Accurate Load Cells with Built-in Analog and Digital Electronics


Machine manufacturers often need to measure compression or tension forces or weights with a good resolution even with environment electrical noise ( from inverters, electrical actuators etc.).


DS Europe is proposing series 500QD load cells that can optionally have a built-in analog or digital electronics therefore allowing a measure protected from electrical, to avoid bulky and expensive external boxes and to have a pre-calibrated load cell. The built-in electronics, being very close to the strain gauge bridge that generates the analog signal, would allow to have a very high resolution therefore small variations of load can be shown stable on the display.


Main feature of series 500QD are: Measuring ranges: 0 to 2-3-6-12-25-60-110-220-330-550-1000-2000-3000-4000Kg FS; Accuracy: <  ±0,023% (up to 60Kg ) and 0,05 ( from 110 to 4000Kg FS); Analog outputs: 2 mV/V, 5 V, 10 V e 4-20 mA; Digital outputs: RS485, RS422 (Modbus and DSEnet protocols) and CANopen (profile DSP406).


Digital output advantages: Differential data transmission allows high protection against electromagnetic noise, high resolution (24 bit A/D converter), cabling cost saving (parallel of many load cells on a single digital input port on PLC or computer), load cell zeroing (for recovering tare, damages, thermal drifts)


Applications: Weighing, automation, medical machines, machine tools, textile machines, test machines, plastic injection machines, presses, research, vehicles etc.


DS Europe can produce transducers accordingly to customer’s technical specifications.
