PicoStrain: Strain Gauge / Load Cells
Compact System-on-Chip for Strain Gage Applications
The PS09 is the latest member in the PICOSTRAIN product family of integrated circuits for measuring strain gauges.
It represents the next step towards higher integration and improved functional density.
The PS09 takes the full advantage of the PICOSTRAIN digital measuring
principle and allows very compact and cost effective designs with very
few external components. It perfectly suits to systems and
instrumentation where the result should be provided digitally, via SPI,
IIC or UART. Such as system is for instance a Digital Load Cell (DLC)
which directly integrates the electronics into the sensor and comes with
many benefits therefore, e.g. good EMI behavior, compact design, easily
applicable temperature compensation, etc.
Like other members of the PICOSTRAIN product family PS09 supports the connection of only a half-bridge as sensor without any loss in resolution quality. However, unlike its ancestors the PS09 contains additionally an internal temperature unit which allows a convenient temperature compensation of half-bridge sensors without any additional external compensation resistors. This way, the whole sensor gets simpler and the temperature compensation more convenient than ever before. Here again, especially the Digital Load Cell takes full advantage of this new feature:
