Miniature Basic Pressure Sensors Offset Compensated Pressure Sensors * 0 to 1 "H2O to 0 to 30 "H2O Pressure Ranges * 0.5 % linearity * Offset Compensated sensors Features General Description The Miniature BASIC series pressure sensors are based upon a proprietary technology to reduce the size of the sensor and yet maintain a high level of performance. The technology is currently being patented. Output offset errors due to change in temperature, stability to warm-up, stability to long time period, and position sensitivity are all significantly e www.allsensors.com * Medical Instrumentation * Environmental Controls * HVAC all Applications These offset 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. The output of the device is ratiometric to the supply voltage and operation from any D.C. supply voltage up to +6V is acceptable. p 408 225 4314 stress concentration enhanced structure to provide a very linear output to measured pressure. f 408 225 2079 reduced when compared to conventional compensation methods.
