NPC-100 and NPC-120
Series Specifications
The NovaSensor NPC-100 and NPC-120 Series pressure
sensor are specifically designed for use in disposable
medical applications. The devices are compensated and
calibrated per the Association for the Advancement of
Medical Instrumentation (AAMI) guidelines for industry
acceptability. The sensors integrate a high-performance,
pressure sensor die with temperature compensation
circuitry and gel protection in a small, low-cost package.
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
micromachined sensing element is used to meet or
exceed all industry requirements while minimizing
assembly and test cost for maximum customer
value. Thick-film laser-trimming is employed for final
compensation and calibration. Sensitivity is maintained to
±1% and linearity is better than 1% in the physiological
operating pressure range.
The NPC-100 and NPC-120 Series are batch-
manufactured in ceramic plate form and shipped as
an intact array or in Tape and Reel for easy customer
automation. This assembly method draws from well-
established manufacturing techniques used in the
electronics industry in order to produce a quality, high
volume product.

* 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.

2. Contact pads are suitable for soldering.
3. Split pads on +Out and –Out must be connected for proper operation.
4. All dimensions assume a nominal 0.01 in (0.25 mm) distance between the
edge of the solder pads to the edge of the ceramic. This distance will vary
slightly from part to part.
