* 1. All values measured at 6 VDC and 71.6°F (22°C) and after five second warm up unless
otherwise specified.
2. Output of sensor with no pressure applied and a 150 kΩ resistor shorted across +IN to +OUT.
3. Over a temperature range of 59°F to 104°F (15°C to 40°C).
4. Normalized offset/bridge voltage—8 hours after 20 seconds. warm-up.
5. Previously qualified, not tested in production.
6. Deviation from straight line drawn through zero and 100 mmHg data points.
7. These sensors are compatible with ETO (ethylene oxide) sterilization. The user is responsible for
establishing and validating suitable process conditions to prevent damage to the sensor.

The NPC-100 and NPC-120 Series are manufactured
in a class 1000 clean-room to minimize possible
sources of contamination. A specially designed silicon
