Embedded Digital Load Cell Converter /Strain Gauge Digitizer Module (DCell)

Very high performance embedded digital load cell converter or strain gauge digitizer module signal converter supplied in a miniature format designed specifically to be incorporated directly into strain gauge sensors such as load cells, pressure transducers and torque sensors. The DCell offers high speed and high precision digitizing capabilities, along with linearization and temperature compensation.

The DCell has conversion of standard strain gauge load cells to digital load cells.

This high performance digital load cell converter embeds directly into load cells, pressure transducers and/or torque sensors

The DCell output formats options include the RS485, ASCII, Modbus, MantraCAN (J1939). All are 4 wire bus and power formats offering connection of up to 32 sensors on just 4 wires.

DCell Additional features are:-
Remote shunt calibration
Temperature compensation
Peak and trough recording
Long cable lengths up to 1000m

  • Strain gauge to RS485 or CAN digital load cell converter
  • Low profile, small 20 mm diameter for mounting inside sensor
  • Auto calibration or direct entry of mV/V with linearisation
  • Ultra high performance, resolution of 1 part in 200,000 (18bit)
  • Error reporting including strain gauge fault conditions
  • Programmable dynamic filter
  • A miniature digital temperature sensor module for wiring to DCell/DSC temperature sensor pcb board is also available (shown on thumbnail image on left)
  • Option of an in-line enclosure (shown on thumbnail image on left)
  • ATEX component approval for hazardous zone 2
