Miniature Ampli ed Low Pressure Sensors Low Pressure (0.5 H O to 30 H O) Sensors 2 2 Features 0 to 0.5 H O to 0 to 30 H O Pressure Ranges 2 2 Temperature Compensated Calibrated Zero and Span Applications Medical Instrumentation Environmental Controls HVAC General Description The Miniature Ampli ed Output pressure sensor is based upon a proprietary technology to reduce all output offset or common mode errors. This model provides a calibrated ampli ed 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 signi cantly 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 uids such as air, dry gases and the like. The output of the device is ratiometric to the supply voltage and operation from any D.C. supply voltage between 4.5 and 5.5 Physical Dimensions Equivalent Circuit Product Label Placement on Backside Lid Vs 12.70 7.17 0.500 0.282 0.64 10.79 2.09 0.025 0.425 0.082 1.78 2.12 2.12 0.070 0.084 0.084 Port B - Vout 1.16 0.046 + 1.01 0.040 Gnd Port A 0.51 2.54 0.25 0.020 0.100 0.010 NOTES Pin 1 2 3 4 1) Dimensions are in inches mm . 2) For suggested pad layout, see drawing: PAD-01 D1 version, D2 version, G verison Pin 1: Vs Pin 2: Gnd Pin 3: Vout Pin 4: Do Not Connect Approvals MKT DATEMFG DATEENG DATEQA DATE As Is With Change As Is With Change As Is With Change As Is With Change All Sensors DS-0101 Rev B 9.81 0.386 6.45 0.254 9.65 15.75 0.380 (nom) 0.620 2.73 10.79 0.108 0.425 2.04 0.080 2.14 0.084 a 16035 Vineyard Blvd. Morgan Hill, CA 95037 p 408 225 4314 f 408 225 2079 e www.allsensors.com all sensorsPressure Sensor Characteristics Maximum Ratings Environmental Speci cations +4.5 to +5.5 Vdc Supply Voltage, Vs Temperature Ranges 10 psig Common-mode pressure Compensated 5 to 50 C 250C Lead Temperature Operating -25 to 85 C (soldering 2-4 sec.)
