PRECISION
Pressure & Temperature Transmitter
AST20PT
Overview
The AST20PT is a digitally compensated pressure and temperature
dual output transmitter, offering measurements from a single process
point, reducing process penetration points and leaks. Krystal Bond™
Technology alone offers excellent non-linearity and non-repeatability
performance. When it is combined with the ASIC, the AST20PT steps
into its own league of high performance pressure sensing at an
affordable price.
