Digital Front End for Measurement of Strain Gage
The PSØ21 is a digital front-end device for measuring strain
gages. Using PICOSTRAIN® measuring principle the PSØ21
provides a high degree of flexibility.
Low Current - High Precision - Beats 24-bit A/D Converters
The current consumption
of the total system, including the sensor, can be reduced
down to less than 100 μA. The precision to be achieved is
better than with most 24-bit A/D-converters and even surpasses
them at high measurement rates.
Full, Half, and Wheatstone Bridge Combinations Capable
The PSØ21 is capable of measuring 2 Wheatstone bridges,
2 full or 4 half-bridges. Driving one half bridge is also possible
without any loss in precision. An additional port for temperature
measurement, patented compensation methods and a serial
SPI interface offers the PSØ21 as an innovative front end to strain gage applications.
