AST20HA

Pressure Sensor - Industrial ASIC - Stainless Steel Media Isolated

AST20HA 0.1% Pressure Transducer product photo

The AST20HA is a digitally compensated 0.1% 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 ASIC, the AST20HA steps into its own league of high performance pressure sensing at an affordable price.
