Haier Group plans to invest RMB 500 million to build the photoelectric information industry base of Haier (Yang) Industrial Park. Recently, Haier signed a contract with Shenbei New District of Yangzhou City, Liaoning Province. Haier (Yang) Industrial Park Optoelectronic Information Industry Base mainly produces LED products. The first phase is scheduled to start in April 2011 and will be completed and put into production by the end of 2012. After the project is put into production, the annual output value is expected to be 500 million yuan. At present, Haier Group has built two industrial and logistics parks in Shenyang.
Yuhai Company is engaged to research
and development of piezoelectric products
and related piezoelectric products, the related piezoelectric products includes the piezo sensors and transducer.
The Ultrasonic Transducer is a kind of transducer that converts the ultrasonic signal into electric signal, or vice versa. Ultrasound transmitter and receiver is a transducer that can transmit and receive ultrasound. Ultrasound sensor is a kind of sensor, in essence, it is also a transmitter and receiver. The working principle of this kind of equipment is similar to that of radar and sonar. Active ultrasonic sensors can emit and receive reflected waves, and determine the distance of the target by measuring the time interval between transmission and reception. Passive Ultrasonic Sensor is actually a microphone that can convert ultrasonic signal into electrical signal.
