Precision Pressure Temperature Transmitter

AST20PT

Precision Pressure and Temperature Transmitters / AST20PT

The AST20PT is a digitally compensated pressure and temperature transducer / 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.

CE Certified
