Aircom Offers Temperature Compensated Explosion-Proof Pressure
Aircom Instrumentation partner American Sensor Technologies,
Inc. (AST) unveils the new digitally compensated high accuracy
pressure transmitter (AST46HA) to complement its existing 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 AST46HA is extremely versatile and
suitable for a variety of applications including, but not limited
to: SCADA systems, well site optimization control units and compressor
The AST46HA'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
Technology, bringing the AST46HA into it's own league of
high performance pressure sensing. The AST46HA 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 20,000psi.
More specifically, the AST46HA series provides pressure ranges
from 0-1 psi to 0-20,000 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.
This model is approved with CSA for hazardous
locations and is also certified as a "single seal"
device to the ANSI/ISA 12.27.01-2003 requirements for process
