Bestech Australia present the AST20HA digitally compensated pressure transducer/pressure transmitter from American Sensor Technologies. The AST20HA digitally compensated pressure transducer/pressure transmitter offers high performance over temperature, with real time thermal compensation and linearity correction.
The Krystal Bond technology offers non-linearity and non-repeatability performance. The accuracy (combined non-linearity, hysteresis and non-repeatability) is below ±0.1% FS, and stability (1 year) is typically ±0.1% FS.
Pressure ranges vary from 0-25psi to 0 to10 000psi. Proof pressure is 2x the standard rated pressure, and these pressure transducers can survive over 100 million pressure cycles. Outputs that are available include 4 to20mA, 1 to5V, 1 to10V and 0.5 to 4.5V ratiometric.
The pressure transducer/transmitter has a compensated temperature range of 0° to 70°C. It can survive shocks of 100g for 10ms and vibration of 10g peak, 20 to 2000Hz. The unit is sealed to an IP66 rating.
This pressure transducer finds applications in military/aerospace vehicles and equipment, in medical laboratories, and in analytical instruments. It is available in Australia and New Zealand from Bestech Australia.
