1230 UltraStable PC Board Mountable Pressure Sensor 0-100 mV Output Current Excitation Gage, Differential, and Absolute Temperature Compensated DESCRIPTION The 1230 is a high performance temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-in-line configuration. It uses Measurement Specialties proprietary UltraStable die to provide excellent performance and long-term stability over wide temperatures. Integral temperature compensation is provided over a range of -20C to +85C 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%. Absolute, differential and gage pressure ranges from 0-15 to 0-100 psi are available. Multiple lead and tube configurations are available for different applications. Please refer to the 1210 and 1220 for information on products with operating pressures less than 0-15 psi. For voltage excitation, please refer to the Model 1240.
