YWKM-1A high-frequency dynamic pressure transmitter
The YWKM-1A high-frequency dynamic pressure transmitter is made by utilizing the extremely high Young's modulus of elasticity and excellent mechanical properties of semiconductor silicon, allowing the sensor to have a high natural frequency. Combined with our company's advanced internal and external structural design, it reduces frequency loss. Thus obtaining a high response frequency and rise time, it is an ideal product for measuring high-frequency dynamic pressure.
