Controlling motor vehicle cooling circuit

摘要

The data acquisition module (15) consists of a capacitative or resistive on/off level sensor and a thermistance located at the cylinder head outlet. It is connected to the motor control calculator (9) and indicator (14). For a supply voltage of 5v, output voltages of less than 0.2v indicate low fluid level, of 0.2-4.8v various temperatures and higher voltages a fault in the metering system.
