Traditional monitoring of fill levels and temperatures occurs with modern control units. Current measurements in conductor loops give information on a worn brake pad.

Moreover, various fill level sensors provide data that is shown to the driver optically and/or acoustically. The "on-board computer" educational system monitors:

  • the coolant and the windshield washer fluid levels,
  • the brake fluid and motor oil levels,
  • the wear on the brake pads,
  • the motor oil and coolant temperatures.

The oil sensor is a continually measuring thermal oil level and oil temperature sensor (TOG) that can be filled with motor oil. Optionally, regulation resistors can simulate the signals. The signal produced converts the information on the oil into a combined PWM (pulse-width modulation) and PFM (pulse-frequency modulation) signal, that Sensor-CASSY can chart, for example.

The signal from the coolant's temperature sensor can also either triggered either by immersion into warm water or by setting a potentiometer. An appropriate holder is available for parallel temperature measurement with a temperature sensor (666212). In the uncoupled state, the real temperature and the resistance can for example be measured with Sensor-CASSY and analyzed as an NTC curve.
