Notes:
1. Reference conditions (unless otherwise noted); T
A
= 25 °C [77 °F], Supply V
S
= 10 Vdc ±0.01 Vdc or I
S
= 1.5 mA ±0.0015 mA.
2. Full-scale span (FSS) is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure. FFS is
ratiometric to the supply voltage.
3. Pressure non-linearity is based on best-fit straight line from the zero to the full-scale pressure. Pressure 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 or span over the compensated temperature range, relative to the 25 °C [77 °F] reading.
5. Response time for a 0 psi to full-scale span pressure step change, 10 % to 90 % rise time.
6. Long term stability over a six month period.
7. Common mode voltage as measured from output to ground. For higher levels of common mode voltage, contact the factory.
8. Pressure overrange: Top: 5 x full-scale pressure or
≤350
psi, whichever is less.
9. Pressure overrange: Bottom: 3 x full-scale or
≤50
psi, whichever is less.

STANDARD COMPENSATION AND TRIM CHOICES
For maximum convenience, the 1800/1805 Series is
temperature compensated from -1 °C to 54 °C [34 °F to
129 °F]. Other temperature ranges are available upon request.
Normalized Output Option:
For design convenience and
sensor interchangeability, the 1800/1805 Series is available
with normalized output (100 ±2 mV dc in current excited
versions with pressure range >3 psi). Normalized output for
current excited 3 psi devices is 75 ±2 mV dc.
ELECTRICAL CONNECTIONS
Laser Trim:
Compensation is accomplished by using an in-
house laser trim facility that allows for tighter product
performance control and improved flexibility in response to
special customer performance requirements.
Resistors:
This option includes a printout of suggested
temperature compensation and zero offset resistor values for
each individual sensor.
