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 -20°C to +85°C 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.

1. Ratiometric to supply current. Span for 2PSI is 30 to 60mV.
2. Best fit straight line. Non Linearity for 2 PSI is ±0.2% and 5 PSI is ± 0.5%.
3. Maximum temperature error between -20°C and +85°C with respect to 25°C.
4. Short term stability over 7 days with constant current and temperature.
5. Long term stability over a one year period with constant current and temperature.
6. For a zero-to-full scale pressure step change.
7. 2X maximum for 100 psi device.
