Features This model provides a calibrated millivolt output with superior output offset characteristics. Output offset errors due to change in temperature, stability to warm-up, stability to long time period, and position sensitivity are all significantly reduced when compared to conventional compensation methods. In addition the sensor utilizes a silicon, micromachined, stress concentration enhanced structure to provide a very linear output to measured pressure. These calibrated and temperature compensated sensors give an accurate and stable output over a wide temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. www.allsensors.com p 408 225 4314 +Vs upply -Vout +Vout Pin 1: N/C Pin 2: +V supply Pin 3: +Voutput -Vs upply Pin 4: -Vsupply Output Resistance 1.5 k ohm Approvals MKT As Is DATE With Change All Sensors MFG As Is DATE With Change ENG As Is DS-0091 Rev C DATE With Change QA As Is DATE With Change R Original On File 4.5 k ohm Signed Original O Pin 6: N/C Input Resittance www.allsensors.com R Pin 5: -Voutput R Signed Original On File Equivalent Circuit Signed Original On File Physical Dimensions www.allsensors.com R The output of the device is ratiometric to the supply voltage and operation from any D.C. supply voltage up to +16 V is acceptable. ors.com e www.allsensors.com The Millivolt Output pressure sensor is based upon a proprietary technology to reduce all output offset or common mode errors. f 408 225 2079 Signed Original On File General Description R www.allsensors.com * Medical Instrumentation * Environmental Controls * HVAC Signed Original On File R Applications www.allsensors.com all sensors * 0 to 0.5" H2O to 0 to 30" H2O Pressure Ranges * Temperature Compensated * Calibrated Zero and Span a 16035 Vineyard Blvd. Morgan Hill, CA 95037 Signed Original On F R Low Pressure (0.5" H2O to 30 " H2O) Sensors R www.allsensors.com w.allsensors.com Signed Original On File Millivolt Output Pressure Sensors Signed Original On F R Environmental Specifications 16 Vdc Supply Voltage Vs, max -10 to +10 psig Common-mode pressure 270C Lead Temperature, max (soldering 2-4 sec.)
