ZJ-3 quasi static d33 measuring meter
ZJ-3 quasi static d33 measuring meter is a special instrument for measuring the pressure of constant d33 and design, it can be used to measure with high piezoelectric constant of the piezoelectric ceramic, small piezoelectric constant of piezoelectric single crystal and piezoelectric polymer materials. In addition, for arbitrary orientation of measuring pressure in single crystal and some piezoelectric devices equivalent piezoelectric d 'constant 33, measuring instruments wide range and fine resolution, high reliability, simple operation, on the size and shape of the sample without special requirements, wafer, a circular ring, a circular pipe, square, rectangular, cylindrical and hemispherical shell can be measured, measurement results and polarity in the three and a half digital panel table displayed directly.
一、The main function of the product:
1.* d33 constant measurement of piezoelectric materials
2.* measurement of piezoelectric ceramics with high piezoelectric constant
3.* measurement of small piezoelectric constants of piezoelectric crystal and piezoelectric 4.polymer materials
5.* measurement of arbitrary orientation of piezoelectric crystals and some equivalent piezoelectric devices of piezoelectric d '33
