Digitally compensated CE-approved high-accuracy pressure transducer is intended for use in applications requiring high performance over a range of operating conditions.
American Sensor Technologies has a new digitally compensated CE-approved high-accuracy pressure transducer that complements its existing OEM and hazardous area pressure sensing products.
The AST20HA is intended for use in applications requiring high performance over a range of operating conditions at an affordable price.
The new sensor 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 on the proven performance of AST's Krystal Bond technology, bringing the AST20HA into its 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 nonrepeatability and long-term stability.
Moreover, this model operates at a wide temperature range (-40 to +85C) and offers pressure ranges up to 689bar.
More specifically, the AST20HA series provides pressure ranges from 0-1.7 to 0-689bar, and is available in compound ranges up to 172bar.
Output options include: 4-20mA, 1-5V, 1-10V and 0.5-4.5V ratiometric.
