The Digital Output pressure sensors are based upon a proprietary surface mapping technology to produce a fully digital
output that virtually eliminates all repeatable errors over temperature and pressure. This series provides a 12 bit digital
serial output (14 bit in High Resolution Mode) with superior offset, span and linearity characteristics. The output is SPI and
MICROWIRE/PLUS
®
compatible as well as fully compatible with the All Sensors GA142 Series sensors.
In addition to synchronous communications, the Digital Output pressure sensors incorporates a bi-directional, TTL level,
asynchronous serial interfaces mode (hardware selectable 9,600 or 19,200 baud). This mode includes a command set that
allows the host to interrogate the sensor for model information, pressure range, serial number, pressure units and
conversion factor. The command set also allows the host to select a high resolution output mode, make minor adjustments
to offset and has an addressable feature that alows multiple sensors to be tied to the same interface buss.
This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. All signals
are 5V TTL/CMOS compatible.
