MODEL 1220
Board Mountable Pressure Sensor 0-50 Output Gage, Differential Absolute Temperature Compensated Process Control Medical Instrumentation HVAC Barometric Pressure Flow Management Avionics
Model 1220 temperature compensated, piezoresistive silicon pressure sensor packaged dual-in-line configuration intended cost sensitive applications where excellent performance long-term stability required. Integral temperature compensation provided over range 0-50°C using laser-trimmed resistors. additional laser-trimmed resistor included normalize pressure sensitivity variations setting current drive sensor bridge, resulting interchangeability prior amplification. Gage, absolute, differential pressure ranges from 0-100 available. Multiple lead tube configurations also available customizing package specific applications. Please refer pressure section information products with operating pressures less than PSI. compensated sensor using gain resistor opposed current resistor, please refer Model 1210.
