* 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 kW 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.

SeriesSpecifications

The NovaSensor NPC-100 and NPC-120 Series

pressuresensorarespecificallydesignedforusein

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

circuitryandgelprotectioninasmall,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

requirementswhileminimizingassemblyand

laser-trimmingisemployedforfinalcompensation

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

drawsfromwell-establishedmanufacturing

techniques used in the electronics industry in order

to produce a quality, high volume product.
