Benefits
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.
