Dynon Avionics’ capacitance-to-voltage
converter is suitable for general use with most capacitive plate fuel level
sensors. It accepts an input via a female BNC and outputs a dc voltage
signal that can be read by the EMSD120. It requires 10 Vdc to 15 Vdc for
power and draws minimal current. We recommend that you connect the capacitance-to-voltage
converter to the EMS for power as shown in the table below, but it will
also work properly when connected directly to standard 12 volt aircraft
power. If your aircraft runs on 28 volt power, you must connect the capacitance-to-voltage
converter to the EMS for its power source. Voltage inputs higher than 15
volts will damage the device.
