在许多应用中,只有最大或最小液位必须测量,但是由于这很可能是报警或危险指示,所以其精度和可靠性必须高。与消费市场相关的应用电子仪器产业在迅猛发展,这种趋势肯定还要持续下去。目前,不仅研制出许多新功能的传感器,而且现有的传感器性能也日臻完善,提高了系统的可靠性和效率。 In many applications, only the maximum or minimum level must be measured, but since this is most likely an alarm or hazard indicator, its accuracy and reliability must be high. The consumer electronics market, which is associated with the consumer market, is booming and this trend must have continued. At present, not only the sensor with many new functions has been developed, but also the existing sensor performance has been improved, which has improved the reliability and efficiency of the system.
