Ares Series
PCB Mounted Pressure Transducers
Amplified Output
Differential and Gage Pressure
Temperature Compensated
DESCRIPTION
The Ares Series
is a small, low cost pressure
transducer, which is able to measure pressures as
low as 0 to 5 inches of water, 0 to 10 inches of
water, 0 to 15 inches of water, and 0 to 1 psi.
Sensitivity to extremely low pressures combined
with the small physical size make this device
ideally suited for application such as HVAC,
medical equipment, and flow monitoring.
The GA100 series has a 4V span from 0.50V to
4.50V and the GA200 series has a 3.75V span from
0.25V to 4.00V.
The plastic housing design for the Ares Series
makes the device very user friendly. The housing is
designed to be printed circuit board mountable,
requiring no additional hardware. Built into the
housing are self locking pins which insure a secure
fit between the housing and the PCB. The pressure
ports are 3/16" barbed ports which mate with
industry standard 1/8" or 3/16" ID tubing. These
ports are mounted 90° to the printed circuit board
to allow other boards to be located above the
sensor.

Small Size
PCB Mountable
Solder Reflow Capability
Barbed Pressure Ports
Dry/Dry Differential Transducer
The ARES series
utilizes a uniqe
sensor circuit
design to
provide ASIC
digital error
correction and
signal
amplification
while maintaining
an analog signal
path. This technique
delivers the high level
of error correction
associated with microprocessor-based circuits,
while maintaining a typical bandwitdth of >1 kHz
generally found only in analog circuits. The result
is a pressure sensor that offers theultimate in low-
cost and high accuracy, while preserving the fast
response and smooth output inherent to silicon
sensors.
The ASIC is a mixed signal CMOS sensor
interface that uses differential switched capacitor
architecture, and was specifically designed to
compensate for the errors associated with
piezoresistive silicon sensors. This ASIC design
reduces the external parts requirement for
calibration, allowing a smaller overall PCB size
while maintaining outstanding performance
characteristics. Due to its small size, barbed
pressure ports, and solder re-flow capability, the
Ares pressure transducer is ideally suited for a
wide range of applications.

1. Span is defined as the algebraic difference between the electrical output
at full scale pressure voltage and the electrical output at zero pressure.
2. Output is ratiometric to input voltage variation.
3. Over compensated temperature range in reference to 25°C.
4. Humidity: 95% non condensing.
5. For differential applications, the input pressure to Port A must be higher
than Port B.
