1210 1psi PC Board Mountable Pressure Sensor 0-100 mV Output Current Excitation Gage and Differential Temperature Compensated DESCRIPTION The 1210 1psi is a temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-in-line configuration. It is 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 laser-trimmed resistor is included to normalize pressure sensitivity variations by programming the gain of an external differential amplifier. This provides sensitivity interchangeability of 1%. Please refer to the 1210 standard datasheet for information on products with operating pressures greater than 1psi. For voltage excitation, please refer to the Model 1220.
