GENERAL DESCRIPTION
These stainless steel devices were
developed for pressure applications that
involve measurement of a hostile media in
harsh environments. These sensors will
accommodate any media that will not
adversely attack 316 stainless steel. This
series uses SenSym´s proven
piezoresistive semiconductor sensor chip
in an oil isolated housing. This design has
proven to be highly reliable,stable and
accurate.
The13U series sensors feature either a
weld ring collar or threaded mail port for
pressure connection.

SPECIFICA TION NOTES:
1. Reference conditions (unless otherwise noted): Supply Voltage, VS = 5 VDC; TA = 25°C;
2. Span is the algebraic difference between the output voltage at full scale pressure and the output at zero pressure. Span is ratiometric to the supply voltage
3. Linearity is based on besst fit straight line. Hysteresis is the maxium output difference at any point within the operating pressure range for increasing and decreasing pressure.
4. Typical error of the offset voltage over the 0 to 50°C reading. Note, the typical temperature coefficients of span and resistance are based on best fit line between 0 to 50°C.
5. Long term stability over a one year period.
6. Response time for 0 psi to full scale span pressure step change
