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.

Notes
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.
