6 FAQs about [Capacitor temperature measurement processing]
What is a capacitive temperature sensor?
A number of capacitive temperature sensors have been introduced in the past. Ma et al., have developed a linear capacitive sensor using a four-layer cantilever beam made of Al, Si3N4, SiO2 and Si thin films . The sensor exploits electrostriction properties of these materials.
What is capacitor condition monitoring?
Capacitor condition monitoring is achieved by measuring the capacitor voltage and exploiting the voltage change over different time scales separately. The capacitor voltage changes during charging and discharging indicate capacitance degradation. Additionally, the junction temperature is monitored by observing the capacitor voltage overshoot during IGBT device turn-off.
Can a MEMS capacitive temperature sensor provide a nonlinear capacitance-temperature response?
In this paper, a MEMS capacitive temperature sensor is presented that can provide a nonlinear capacitance-temperature (C - T) response with high sensitivity in a small temperature range. The sensor sensitivity is defined as the rate of change in capacitance to the rate of change of ambient temperature, dC / dT.
Does capacitor voltage fluctuation affect temperature monitoring?
The experimental results indicate that within the normal operating voltage fluctuation range of SM capacitor, the change in capacitor voltage (Δ Vpk) is less than 0.2%. The effect of fluctuations in capacitor voltage on temperature monitoring is negligible.
Does a capacitive temperature sensor have a high linearity?
The sensor exhibits high linearity in relatively large temperature range (−70 °C to 100 °C). Shavezipur et al. also demonstrated a capacitive sensor with separate actuation and readout that can provide capacitance-temperature response with relatively constant sensitivity .
What is the calculated capacitance?
The calculated capacitance is determined by the voltage waveform of the capacitor discharge process. It has an error of 1.1% compared to the nominal value, which makes it suitable for accurate monitoring of capacitance. The junction temperature estimation result of the IGBT is shown in Figure 13.
