WebMay 27, 2015 · Sawyer–Tower circuit was the method to measure polarization–electric field (P–E) hysteresis loop. The WRHA ceramic has low dielectric constant of 16.4 and dielectric loss tangent of 0.36 at 100 kHz. The highest dielectric constant (65.2) of the specimen possessed by sintering temperature of 900 °C and frequency of 1 kHz. WebThe original Sawyer-Tower circuit is a very practical circuit for hysteresis loops. Besides, it is useful for the material, which has a low loss and high polarization. Fig 1. presents the... WebWe can measure the polarisation by using the classic Sawyer-Tower circuit: In this experiment, the voltage is cycled by the signal generator. Its direction is reversed at high frequency, and the voltage across the reference capacitor is measured. The charge on the capacitor must be the same as the charge over the ferroelectric capacitor, as ... paessler prtg cost
