GENERAL DESCRIPTION
The DC Series pressure sensors combine SURSENSE™ precision high
sensitivity silicon sensing capabilities with the latest in Application Specific
Integrated Circuitry ASIC technology to produce one of the most precise,
reliable pressure sensors in the market. The SURSENSE technology
provides Dynamic Self Compensation which substantially reduces offset
errors due to changes in temperature, stability to warm up, long term
instability and position sensitivity.
When operated with an unregulated 7.0 Vdc to 16.0 Vdc supply the DC
sensors provides a ratiometric 0.50 to 4.50 Vdc output (4.0 Vdc span).
