AST20PT Pressure & Temperature Transducer

Brand: American Sensor Technologies Inc
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.
