Very high performance digital load cell conditioning / strain gauge 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.
Offering conversion of standard strain gauge load cells to digital load cells.
Available output formats include the RS485, ASCII, Modbus, CAN, CANopen® and MantraCAN (J1939). All are 4 wire bus and power formats offering connection of up to 32 sensors on just 4 wires.
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 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.
