Model 1210 Low Pressure PC Board Mountable Pressure Sensor 0-1 PSI 0-100 mV Output Gage and Differential Low Cost Medical Instruments Air Flow Measurement HVAC Process Control Factory Automation Leak Detection DESCRIPTION The Model 1210 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 0-50C using laser-trimmed resistors. An additional lasertrimmed resistor is included to adjust the gain of an external differential amplifier. This provides sensitivity interchangeability of 1%. The sensing element used in the low pressure Model 1210 includes a double bossed design that produces a sensor output of 100 mV (typical) at 1 PSI. The 1210 is also available in ranges up to 0-100 PSI. For a compensated sensor using a current set resistor instead of a gain FEATURES set resistor, please refer to the Model 1220.
