Liquid Pressure Transducer
Description of liquid pressure transducer
Based on MEMS technology, UPC4 high frequency liquid pressure transducer uses integrated silicon diaphragm as sensing element. UPC4'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.
UPC4 high frequency liquid pressure transducer has been widely applied in scientific experiments as military engineering, melt exploding experiment, petroleum, oil well logging, material, mechanics, construction engineering, soil and rock mechanics, the wound medicine, hydraulic pressure power generator experiments, and in the modernization instruments and meters, it is the first choice for dynamic pressure measurement.
