MODEL1220

The MODEL1220 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.Integral temperature compensation is provided over a range of 0-50°C using laser-trimmed resistors. An additional laser-trimmed resistor of MODEL1220 is included to normalize pressure sensitivity variations by setting the current drive to the sensor bridge, resulting in an interchangeability of ±1% prior to amplification.

Gage, absolute, and differential pressure ranges from 0-2 PSI to 0-100 PSI are available. Multiple lead and tube configurations of MODEL1220 are also available for customizing the package for specific applications.

Please refer to the low pressure section for information on products with operating pressures less than 0-2 PSI. For a
compensated sensor MODEL1220 using a gain set resistor as opposed to a current set resistor, please refer to the Model 1210.
