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 batchmanufactured in ceramic plate form and shipped as an intact array or in Tape and Reel for easy customer automation. This assembly method draws from wellestablished manufacturing techniques used in the electronics industry in order to produce a quality, high volume product.
