DESCRIPTION

The Ares Series is a small, low cost pressure transducer, which is

able to measure pressures as low as 0 to 5, 0 to 10, 0 to 15

inches of water, and 0 to 1 psi. The ranges combined with the

small physical size make the device ideally suited for applications

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.

Providing both error correction and signal amplification,

the electronic module’s ASIC uses digital compensation while

maintaining an analog signal path, a unique design among

piezoresistive sensor products. The technique provides the high

level of error correction found in microprocessor-based circuits

but with a typical bandwidth of >1 kHz generally found only in

analog circuits. The result is a pressure sensor that offers the

ultimate 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.
