General Description
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.

Error Codes
This is the compensated temperature range of the part.
Syntax: [low limit]<sp>[high limit]<sp>”C”
Example:-20to85C
-40 to 125 C and custom ranges also available.
The error codes are bits packed within a double byte.
The four character string is an ascii hex expression.
The error code bits are:
Bit 0 : Part not factory compensated
Bit 1 : Tdex Overflow
Bit 2 : Tdex Over-range
Bit 3 : Pdex Overflow
Bit 4 : Pdex Over-range
Bit 5 : PWL Overflow
Bit 6 : Scale Overflow
Bit 7 : High Resolution Overflow
Bit 8 : Pressure Output Limited to Specific Value
Bits 9 through 15 : Reserved
Example:0100
Represents error bit 8 set and the Pressure Output Limited
Notes:
Bit 0 : This should not appear if the part has been calibrated
Bits 1 thru 7 : indicate computational error when compensated
Bit 8: indicates that the pressure applied to the part exceeds the
range of the part and is limit to either the high or low limit
{null}
Null Response
No response from the part. In the event of a serial number
mismatch the part will not respond (to avoid buss contention.)
Specification Notes
NOTE 1: UNLESS OTHERWISE SPECIFIED, ALL PARAMETERS ARE MEASURED AT 5.0 VOLT SUPPLY, POSITIVE PRESSURE APPLIED TO PORT B.
NOTE 2: THE DIGITAL OUTPUT IS A 16 BIT SIGNED BINARY OUTPUT IN TWO’S COMPLIMENT FORMAT. THE APPLIED PRESSURE IS COMPUTED USING THE PRESSURE CONVERSION
A
TABLE (BELOW). THE MODE COLUMN IDENTIFIES THE RESOLUTION OPERATING MODE OF THE DEVICE (A = STANDARD RESOLUTION, B = HIGH RESOLUTION). FSO AND
UNITS ARE SHOWN FOR EACH MODEL.
NOTE 3: SHIFT IS WITHIN THE FIRST HOUR OF EXCITATION APPLIED TO THE DEVICE.
NOTE 4: DIGITAL SPAN IS DEPENDENT ON THE RESOLUTION OPERATING MODE. REFER TO THE DIGITAL SPAN TABLE (BELOW) TO IDENTIFY THE DIGITAL SPAN OF THE SPECIFIC
MODEL. IN THE EVENT OF AN OVER-PRESSURE OR UNDER-PRESSURE CONDITION, THE DIGITAL OUTPUT WILL ONE COUNT HIGHER OR ONE COUNT LOWER (RESPECTIVELY) TO
THE LISTED DIGITAL SPAN TO INDICATE THE CONDITION.
NOTE 5: OVERALL ACCURACY INCLUDES THE COMBINED EFFECTS OF OFFSET AND SPAN SHIFTS OVER TEMPERATURE, LINEARITY, HYSTERESIS, AND OFFSET AND SPAN CALIBRATION.
