Good news of our new product: ZA-YD series low-frequency piezoelectric, super-low-frequency vibration velocity/displacement sensors, which are firstly developed successfully by our engineers, now are applied in a large scale in vibration monitoring of a hydroelectric power station and some large bridge. Perfect technical parameters like frequency down to 0.1Hz low are highly appraised by customers.

Success of this product is a symbol that , from now on, traditional magneto-electric velocity/displacement sensor can be totally replaced in absolute velocity/displacement field domestically. Life span is greatly prolonged and reliability is enhanced since the removing of mechanically movable part of magneto-electric vibration sensor.
