Sensors

DESCRIPTION

The 1800/1805 Series sensors are high performance TO-8

pressure transducers specifically designed to address a variety

of both low and medium pressure original equipment

manufacture applications.

The transducers offer two performance grades and a variety of

compensation options, including span and calibration to within

±2 mV (normalized output). The 1800/1805 Series can operate

with either constant current or voltage excitation.

The 1800/1805 Series contains a solid state piezoresistive

pressure sensor mounted in a standard TO-8 package. They

are printed circuit board and pin-for-pin compatible with other

TO-8 pressure sensors.

FEATURES

Notes:

1. Reference conditions (unless otherwise noted); TA = 25 °C [77 °F], Supply VS = 10 Vdc ±0.01 Vdc or IS = 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.

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.
