Product Description:
WF200S Silicon-Structured MEMS Differential Pressure Sensor With A Range Of 0 - 10 kPa Is Used For Medical Monitoring
Features:
WF200S pressure sensor is a fully-silicon-structured MEMS differential pressure sensor.
The WF200S adopts the Hewitt full bridge design. Under the standard operating power supply, it can achieve precise measurement of pressure ranging from 0 to 10 kPa (customizable for multiple ranges), and exhibits a good linear relationship with the output voltage.
The WF200S series pressure generator adopts a dual-sensor air nozzle structure and is packaged in SOIC 16 format.
WF200S is applicable to various medical devices such as blood pressure monitors, ventilators, pulmonary function meters, hemodialysis equipment, and arterial sclerosis detectors.
The WF200S differential pressure sensor supports customisation of multiple measurement ranges.
Current range: 5KPa, 10KPa, 20KPa, 40KPa, 100KPa, 200KPa, 300KPa.
