TO-8, 0 psi to 3 psi, 0 psi to 150 psi Silicon Pressure 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.

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.

Honeywell Sensing and Control 3 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.
