Instead of forming a bridge circuit, the commercial LCR meter is used to measure the reactance of capacitance and inductance standard in the proposed technique, hence reducing the measurement complexity. Results obtained from both the methods are comparable, and the deviation found is within 50 ppm.
The 0.1 µF mica capacitor with connecting leads is measured on the GR1620 Capacitance Bridge in comparison with 1000 pF air capacitance kept in a constant temperature air bath. Reactance is calculated with the measured value of capacitance in GR1620 Capacitance Bridge. Then reactance of the capacitor measured on LCR meter.
Inductance can be determined in terms of capacitance standard by direct measurement of capacitive reactance on the LCR meter. The conventional Maxwell–Wien bridge is currently used at CSIR-NPL to determine traceability to the inductance standard through capacitance and two resistance standards.
TI's inductive and capacitive portfolio consist of LDC and FDC devices. Inductive sensors detect the proximity of metal targets to an inductive coil sensor, whereas capacitive sensors detect the change in capacitance between a sensor and electrode. Figure 4-2.
Measurement uncertainty of mica capacitor is 40 ppm which includes repeatability in measurement and impact of temperature on capacitance standard [ 11 ]. Once the mica capacitor's traceability is established, it is used to calibrate the LCR meter for capacitive reactance.
Present work can be used to calibrate inductance standards by utilizing the error evaluated at the same nominal value of reactance of a capacitance standard. Inductance can be determined in terms of capacitance standard by direct measurement of capacitive reactance on the LCR meter.
