 ASIC Compensation

 Superb Temperature Performance

 Real Time Thermal Compensation

 Real Time Linearity Correction

 Turndown Capability

The AST20PT is a digitally compensated pressure and temperature dual

output transmitter, offering measurments 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.

AST20PT

Precision Pressure & Temperature Transmitter

Performance @ 25°C (77°F)

Accuracy* < ±0.1% BFSL (<±0.2% BFSL over 15,000 PSI)

Stability (1 year) ±0.1% FS, typical

Proof Pressure ** 2X Rated Pressure, standard

Burst Pressure 5X or 50,000 PSI, whichever is less

Pressure Cycles > 100 Million

* Accuracy includes non-linearity, hysteresis & non-repeatability **For higher proof pressures, contact factory

For units with loop-powered 4-20mA output, the pressure loop must be powered or the temperature output will not operate.
