LED光柱血压计灵敏度高,无水银泄漏,无传统水银柱血压计常见的零位偏差及无灵敏度或灵敏度小等缺点,在保留传统水银柱血压计简便直观的模拟式血压观测窗的同时,即使在照明不佳的环境中仍能清晰观察血压示值。但是,LED光柱血压计计量是否准确呢?这是我们最关心的问题。从工作原理上讲,水银血压计的工作原理是根据流体静力平衡原理,由连通器把贮汞瓶与示值管连通,当贮汞瓶内的水银表面受压后,迫使示值管内水银升高而指示出压力值。LED光柱血压计的工作原理:根据压力传感器的工作原理,当压力传感器受压后,由控制电路驱动装有LED发光二极管的光栅条,使光栅条内的LED发光点增多或减少而指示出压力值。
LED light column sphygmomanometer high sensitivity, no mercury leakage, no traditional mercury sphygmomanometer common zero deviation and no sensitivity or sensitivity and other shortcomings, while retaining the traditional mercury sphygmomanometer simple and intuitive analog blood pressure observation window at the same time, even if In poor lighting environment can still be clearly observed blood pressure indication. However, LED light sphygmomanometer measurement is accurate? This is our most concern. Working principle, the working principle of mercury sphygmomanometer is based on the hydrostatic balance principle, by the communicator to connect the mercury storage bottle and the indication tube, when the surface of mercury in the mercury storage bottle is pressed, forcing the indicator tube mercury Raise to indicate the pressure value. LED light bar blood pressure meter works: According to the working principle of the pressure sensor, when the pressure sensor is pressured by the control circuit driven with LED light-emitting diode grating bar, so that the LED bar within the light-emitting point increases or decreases and indicates the pressure value.
