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

Try our ready to go Evaluation Kit  which includes one free DCell or DSC card.

First select the DCell you require and ask for the appropriate Evaluation Kit as an accessory item. See our Videos above for 'Getting Started with the Evaluation Kit' video.

For packaged options for mounting external to the sensor,- see models DSC Strain Gauge or Load Cell Digitiser Module, DSJ1 Strain Gauge or Load Cell Digitiser Module (1 Channel) and DSJ4 Strain Gauge or Load Cell Digitiser Module (4 Channel).

Product order options

Please read the following before selecting the options for this product:

The Embedded Digital Load Cell Converter or Strain Gauge Digitizer Module, the DCell is available in two main versions, differing only in performance and cost. These versions are the industrial stability (suitable for most industrial measurements) and the high stability (for very high precision measurements). Either type is available with various communications options, selectable from the list below.

Note also that the Evaluation Kit does not include the DCell so it is necessary to first select the DCell then select the appropriate Eval Kit as an accessory item.

Q: You offer two versions – industrial stability and high stability - of the DSC and DCell, what is the difference?

A: The Industrial Version offers 25ppm basic accuracy (equates to 16 bit resolution). The High Stability version offers 5ppm basic accuracy (equates to 18 bit resolution) with comparable stability which far exceeds standard instrument performance.

Q: Are the DSC devices low-power?

A: Yes, low-voltage DC supply (5.6V min), typically 40mA for RS485 &.52mA for RS232 (including 350R strain gauge).

Q: Is there adjustable sensitivity?

A: Yes, the DSC devices can be configured for standard 2.5mV/V full-scale strain gauges as supplied. A single additional resistor configures the input between 0.5 and 100 mV/V full-scale.

Q: Do you offer linearity compensation?

A: Yes, advanced 7-point linearity compensation.

Q: Are there self-diagnostics?

A: Yes, the DSC devices offer continuous monitoring for faults such as strain overload, over/under-temperature, broken sensors or unexpected power failure. All fault warnings are retained on power-fail.
