1230-030D-3S - Measurement Specialties

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.
