宝德 449673 burkert宝帝流量计8045he baode electromagnetic flowmeter is often made into round plates in the piezoelectric elements and vibrates along the thickness. The wafer is more than 10 times the thickness of the thickness to ensure the direction of the vibration. The materials of piezoelectric elements are mostly leaded by zirconate titanate. In order to fix the piezoelectric elements, the ultrasonic is injected into the fluid at the right Angle, and it is necessary to construct the transducer integral (also known as the probe). The material of the acoustic wedge not only requires high strength and aging, but also requires that the energy loss of the ultrasonic wave after the acoustic wedge is small i.e. the transmission coefficient is close to 1. The commonly used wedge material is plexiglass, because it is transparent and can observe the assembly of piezoelectric components in the acoustic wedge. In addition, certain rubber, plastic also can hold the wedge material.
