Specification notes:
1.
Reference conditions: supply voltage, V
S
= 12V
DC
; T
A
= 25°C; common mode line pressure = 0 bar; pressure applied to high
pressure port.
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.
Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and decreasing
pressure.
4.
Maximum error band of the offset voltage and the error band of the span, relative to the 25°C reading.
5.
Maximum difference in output at any pressure within the operating pressure range and temperature within 0 to +50°C after:
a) 100 temperature cycles, 0 to +50°C.
b) 1.0 million pressure cycles, 0 psi to full scale span.
6.
Input impedance is the impedance between V
S
and ground.
7.
Output impedance is the impedance between + and - outputs.
8.
This is the common mode voltage of the output arms for V
S
= 12 V
DC
.
9.
Response time for a zero to full scale span pressure step change, 10 to 90 % rise time.
10.
Long term stability over a one year period.
11.
Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters
of the sensing element.
12.
Burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks to
the housing.
