Liquid Pressure Transducer
Description
UPC4 liquid pressure transducer uses integrated silicon diaphragm as sensing element. It's effective size is small, and because of the silicon's fine elasticity characteristic, in addition to the transducer's flush structure, therefore, UPC4's dynamic frequency response is extremely high (max. 1MHz), it may response to the lowest to zero frequency, highest to almost natural frequency, and the level rising time is only microsecond. The overall performance of UPC4 liquid pressure transducer surpasses piezoelectric dynamic pressure transducer.
