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.
