History shows us that creating digital load cells or DLC has been expensive and prohibitive due to difficulty in maintianing temperature compensation. It was hard to get optimum quality dealing with temperature gain and offset drift, but was necessary to meet OIML or NTEP legal specifications.
The construction of a digital load cell is like an analog one with the a difference of putting the digitization on top leaving minimal space for automation and a simple production. This is exactly where PICOSTRAIN excels with its advanced temperature compensation WITHOUT mechanical trimming, the construction of the digital load cell is simplified. |

Make “DLC 2.0”
Following existing production processes, PICOSTRAIN makes easier construction possible. With a simpler production model, costs are reduced and quality is increased. The PICOSTRAIN answer allows for the wholly mouting the load cell with electronics BEFORE addressing temperature compensation. There is nomanual load cell adjustment, as it is done by the chip internally and can be easily automated.
This leads to a number of advantages, such as:
- simplified and more reliable production process
- higher quality using the new adjustment method
- more easily reach specifications like OIML 6000
- full automatic adjustment of gain / zero drift without mechanical trimming
- greater flexibility for standard scale DLCs with easier design and better EMC behavior
- low current consumption and low self heating using the PICOSTRAIN measurement method
- easy DLC replacments for using intrinsically calibrated units
Saving cost and effort come automatically whith this approach and it allows to think about the digital load cell as the successor of the analog load cell in a way that it makes sense in both – technical and commerical aspects!
