Product Description

200Khz ultrasonic transducer for gas flow meter

1.Application

The transducer is used for gas flow measurement. You still need to develop the control board to drive the transducer.

2.Structure

wire connection: red is anode, white is cathode

electricity schematic diagram: no need extra inductance compatible with capacitance

available caliber: 9.1mm

PZT launches polarization: anode
