随着超声波水流量仪表在市场中逐渐推广应用,基于压电陶瓷材料的换能器的研究也越来越深入;由于水流量仪表使用环境通常较为苛刻,产品的可靠性要求较高。对超声波水流量仪表的换能器可靠性进行研究,提出换能器的设计方案,并提出四种可靠性试验方法,对换能器可靠性进行试验。 With the ultrasonic water flow meter gradually popularized in the market, the research on transducers based on piezoelectric ceramic materials is also getting more and more in depth. Due to the harsh environment of water flow meters, the reliability of the products is more demanding. The transducer reliability of the ultrasonic water flow meter is studied, the design scheme of the transducer is put forward, and four reliability test methods are proposed to test the reliability of the transducer.
