The 1220 1psi is a temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-in-line configuration and intended for cost sensitive applications where excellent performance and long-term stability are required.
The 1220 1psi is a temperature compensated, piezoresistive silicon pressure sensor with a 0-1 PSI measurement range. When using the 1220 with a fixed voltage reference and current set resistor as shown in the application schematic, a span of 50mV and 1% interchangeability can be achieved. Integral temperature compensation is provided over a range of 0-50°C using laser-trimmed resistors. Please refer to the 1220 standard datasheet for information on products with operating pressures greater than 1psi. For current excitation, please refer to the Model 1210.
1.0% Interchangeable Span (provided by current set resistor)
