AST Offers Digitally Compensated Pressure Transducer

Mt. Olive, NJ - August 1, 2008. American Sensor Technologies, Inc. (AST) unveils the new digitally compensated, CE approved, AST20HA high accuracy pressure transducer to complement it's existing OEM and Hazardous Area pressure sensing products. This model is intended for use in applications requiring high performance over a range of operating conditions at an affordable price. The AST20HA is extremely versatile and suitable for a variety of applications including, but no limited to: test stands, hydrogen filling stations, medical laboratories and military/aerospace vehicles and equipment.

The AST20HA's ASIC design features real time thermal compensation and linearity correction, enabling it to excel in dynamic temperature environments where ordinary sensors fail. Furthermore, its one piece stainless steel construction is built upon the proven performance of AST's Krystal Bond(TM) Technology, bringing the AST20HA into it's own league of high performance pressure sensing. The AST20HA contains no internal
o-rings, taking the guesswork out of o-ring to media compatibility, and is equipped with 100V/m of EMI/RFI protection from electrical noise. The low operating strain of the diaphragm offers excellent non-repeatability and long-term stability.

Moreover, this model operates at a wide temperature range (-40°F to 185°F) and offers pressure ranges up to 10,000psi. More specifically, the AST20HA series provides pressure ranges from 0-25 psi to 0-10,000 psi and is available in compound ranges up to 2500 psi. Output options include: 4-20mA, 1-5V, 1-10V, and 0.5 - 4.5V ratiometric.
