WF1620D Digital Pressure Sensor Series

WF1620D Disposable Blood Pressure Monitoring Sensors

No Stock

WF1620 Series are compensated and calibrated pressure sensors specifically designed for disposable medical applications. Each device integrates a high-performance silicon pressure sensing element, temperature compensation circuitry, and gel protection in a small, low-cost package. Compensation and calibration are performed in accordance with AAMI guidelines, and thick-film laser-trimming is employed for final adjustment.
