The AST20HA is a digitally compensated precision pressure transducer /

pressure transmitter that offers high performance over temperature. Krystal

Bond™ Technology alone offers excellent non-linearity and non-repeatability

performance. When it is combined with the advanced electronics, the

AST20HA steps into its own league of high performance pressure sensing at

an affordable price.
