The coefficients
K
i, j
,
X
and
Y
are printed on the calibration certificate supplied with the pressure
sensor. A sample set is shown in Table 5:
4.4 Stored Coefficients
The coefficients are also stored internally on a serial EEPROM. See Appendix B for details on
data format and communication information.
The internal EEPROM is only available on some electrical connector variants of the RPS
8XXX
series, see data sheet or calibration certificate for electrical connection details.
5. DPS Pressure Measurement
The pressure reading and pressure units are outputted as ASCII text. The reading rate is user
programmable from ten readings per second to one reading per 9999 seconds.
5.1 Serial Data Communications Settings
Bi-directional digital communication, no handshaking, 9600 baud, 8 bit data, 1 stop bit. The
sensor may be used as a single transducer directly connected to a serial interface. It can also be
part of a network of devices using the programmed addressing facility.
5.2 Applications
The sensor may be used as a single transducer directly connected to a serial interface. It can also
be part of a network of devices using the programmed addressing facility.
X
= Pressure normalizing factor
y
= Temperature signal in mV
Y = Temperature normalizing factor
