NPC-100 Datasheet, PDF (2/4 Pages) List of Unclassifed Manufacturers – NovaSensor Disposable Medical Pressure Sensors

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 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.
