Pressure Transducer / Transmitter
AST20HA
Overview
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.
Benefits
Digital ASIC Compensation
Superb Temperature Performance
Real Time Thermal Compensation
Real Time Linearity Correction
Turndown Capability
Pressures up to 45,000 PSI
ABS (American Bureau of Shipping) Approved
